Multiple antenna (MIMO) sequence of real voice

Figure 5 shows a for TV telephone-based wireless also is for communication system composition.

Also 5 (a) as shown in number of transmit antennas, N_T supplied to the light, number of receive antennas N_R surface lengthened two, transmitter or receiver using multiple antennas only alternatively even if an theoretical antenna in proportion to the number the enhanced capacitance channel transmission. Therefore, improves the transmission rate and thus to prevent the frequency can be. Channel transmission capacity increases, a theoretical framework transmission rate maximum transmission rate in using single antenna (R_o) to rate increment rate (R_i) is multiplied by can be is incremented by a.

For example, 4 and transmission antennas 4 receive antennas MIMO communication system single antenna using theoretical and the second processor is 4 times to acquire transmission rate. Multiple antenna system to increase capacity, higher theoretical certification 90's middle after quality score of each input for transferring data substantial same a dilating various techniques for studied and drinks to date are of wet liquid to flow down. Furthermore, some techniques employ the already 3 generation mobile communication and wireless LAN variety of standard of a wireless communication is reflected in of wet liquid to flow down.

Trends study associated multiple antenna transmitted to a terminal at a portion corresponding to the separable in a multi-channel environment by a multi-antenna in an environment, and multiple access information associated with communication capacity calculation such as study side theory, multiple antenna system of radio channel measurement and model derived study, and rate improved transmission reliability for improving space-time signal processing techniques and drinks in one aspect an of a polyimide resin, such study but the method can not study..

A mathematical modeling method communication in a multi-antenna system, by using a trolley and. specifically,. Said system N_T transmission antennas and N_R receive antennas a home is present.

Surfaces of a transmission signal, N_T transmission antennas if there is a transmission information N_T is 0.2 to 3.2mm2 and the. Transmission information can be representation as follows.

Each transmission information The transmit power can be other. Respective transmit powers Formed on the metal thin film, transmission power controlled transmission information can be representation as follows.

Furthermore, The transmission power of using P diagonal matrix can be representation as follows.

Information vector controlled transmission power To weight matrix W is applied and the actual transmitted N_T-clear-to-send signal Coercivity considering brake only is. Weight matrix W transmission channel information of a transmission each of the antenna according to state, and the like, and to properly so as to be make part. Using the vector X can be representation as follows.

Here, w_ij the i information is transmit antennas and second weights of a second j.. The precoding matrix is referred to W..

Received signal N_R receive antennas an array of antenna elements which transmit if there is a received signal The vector can be representation as follows.

Multiple antenna wireless communication system when for modeling channel in, channel transmitting/receiving antenna can be are index. Transmit antennas which has undergone the channel j received from antenna i h_ij to mark an 1/10 time as large as that of. h_ij in, first index is a receiving antenna order of index, by index is of transmit antennas, to significantly different the later.

While, the 5 (b) also N_T transmission antennas i receiving antenna in is shown in the channeling of the drawing. Said channel pixels displaying the vectors and row and column format in the displays a. In 5 (b) also, total N_T i antenna received from transmission antennas channel arriving to can exhibit as follows.

Therefore, N_T from transmission antennas N_R all channels arriving to receive antennas is represented by the cell as follows.

Actual channel the channel matrix H after the white noise (AWGN; Additive White Gaussian Noise) .are to be added. N_R receive antenna respectively including a white noise is received and added to Can be representation as follows.

Numerical formula aforementioned received signal reproduction of information can be representation as follows.

On the other hand, channel indicative of the state of the cell channel matrix H number of rows and columns of a transmitting/receiving antenna is determined by the number of. Channel matrix number of a receiver antenna number of the row H N_R hard mask as an etching mask, heat the number of the number of transmit antennas, N_T and a equal. I.e., channel matrix H the matrix is N_R × N_T is.

independent each other (rank) rank of matrix (independent) minimum number of columns or rows is defined number. Therefore, memory cells on the row or rank of matrix can't greater than the of heat. Channel matrix H of ranks in one memory device the (rank (H)) is limited as follows.

A matrix defined other rank (Eigen value decomposition) when value decomposition a unique, non -0 can be defined number of eigenvalues. Similarly, another rank when definition singular value decomposition (singular value decomposition), non-specific number of 0 can be defined. Therefore, channel matrix in rank. A given the physical downloads different sets of information for channel in the maximum number can send can be as.

In description of constitution: the invention concerns a method, the MIMO 'rank (Rank)' has made since a specific moment in time and specific frequency resource independently may send a signal which a route that is representative of the number of, 'layer (layer) number of' each is transmitted over the exhibits and number of a signal stream. Generally a rank used in for signal transmission transmitting end corresponds to the number of number of layer since transmitting a no mention of a special rank a layer which equal to the number of. have the meanings.

Reference signal (Reference Signal; RS)

During transmission of packets in a wireless communication system, the packet transmitted across a wireless channel to a transmission process can be corresponding row electrodes are. A deteriorated signal/or the use at the reception in order and properly received a received signal using channel information correcting distortion in.. Channel information for localizing the, data communication in both known signal, said signal through a channel distortion of received channel information has degree method uses method is simple and tray structure. Said signal (Reference Signal) him a pilot signal (Pilot Signal) or reference signal.

The using multiple antenna for transmitting/receiving data between transmit antennas and receive antennas is connected between the second node to know the channel state capable of receiving signals correct.. Therefore, each transmit antenna reference purpose :. signal is present.

Mobile communication system reference signal in the (RS) greatly in accordance with the purpose. can be decomposed into two. One channel information that are to be used for the acquisition and RS, for demodulating the received data on the at least one other of which said is used for RS. Electronic is downlink a obtains channel information to broadband transmitted the new device must be powered on since the RS, specific downlink data sub frame has not received a corresponding even is receiving and measuring a RS should can be. The handover in a such RS for measurement is subjected to a is carried out by using an acidulous. The latter to down link base station sent along resources corresponding introduced as a RS, RS corresponding terminal by receiving and capable of performing a channel estimation, is enabled to demodulate data according. The RS such region in which data is transmitted is to be transferred to..

Existing 3GPP LTE (for example, -8 release 3GPP LTE) unicast system for service (unicast) downlink types 2 defining the RS. A common reference signal one (Common RS; CRS) and, the other a dedicated reference signal is (Dedicated RS; DRS). CRS a channel information regarding a condition acquisition and handover in a for and is used for measuring, etc., cell-specific (cell-specific) RS it is also possible to have a compact design and be mobile. The DRS used for data demodulation, terminal-specific (UE-specific) RS it is also possible to have a compact design and be mobile. Existing 3GPP LTE the DRS system for demodulating the received data on the CRS is used only for a channel information acquisition and a data demodulation noise is removed from the aim a multi can be used.

CRS the cell-specific transmission in the upstream channel is RS, broadband (wideband) sub every respect to boundary line is held for every frame is transmitted. CRS has transmissions of a base station antennas maximum in response to an antennas 4 can be transmitted with port. E.g., base station when two minuses the number of of transmit antennas, for antenna port burn 1 0-th and the CRS is being sent to, personal you for antenna port burn 0-3 when CRS is transmitted respectively.

Figure 6 shows a region of the first active resource blocks pair on CRS and DRS for assisting in the removal of the. surface thereof, and the defining an aiming pattern of the substrate.

In exemplary signal pattern reference of Figure 6, base station a system for supporting antenna two transport 4 one resource block pair (normal CP in the case of, in time 14 of OFDM symbols × 12 frequency and to subcarrier) exhibits pattern of DRS and CRS on. In Figure 6 'R0', 'R1', 'R2' and 'R3' (RE) element resource represented by the, index 0, 1, 2 and 3 for each antenna port CRS. indicative of the position of. While, in Figure 6 'D' LTE element resource represented by a are defined in systems DRS. indicative of the position of.

LTE system evolved LTE-A system in the form of not based on the returned signal, downlink maximum 8 transmission antennas to be able to support a. Therefore, maximum 8 transmitting antennae two RS should also supported. Downlink in system 4 has a maximum RS LTE antennas is defined only for port, 4 base station LTE-A two 8 maximum one or more downlink transmit antennas for antenna port, in their have additional RS should defined. Maximum 8 as RS for port transmission antennas, for channel measurement for a apparatus and method for suppressing and a data RS to an event that both a two RS. have to be considered.

LTE-A the exponential control current system considerations that are important in the one (backward compatibility) is backward compatibility. Acids to epoxygenated fatty acids therein backward compatibility, existing LTE terminal LTE-A system to operate correctly even support the.. Viewed in terms transmission RS, defined in the standard LTE band is CRS every sub-frame is sent whenever the time-frequency range for maximum 8 transmission antennas port when the adding of RS, RS is will be too overhead would be. Therefore, maximum 8 a novel antenna port RS for the exponential control current in response to reduce overhead RS. have to be considered.

A introduced n LTE-A greatly the RS can be classification to 2. One of transmission rank, (Modulation and Coding Scheme; MCS) of the modulation and coding schemes, such as precoding matrix index (Precoding Matrix Index; PMI) for the selection of channel measurement purpose reference signal-channel state information in RS (Channel State Information RS; CSI-RS) and, maximum at least one other of which said two transport 8 which the data is transmitted over the antenna for demodulating the purpose of reference signal demodulation-in RS is (DeModulation RS; DMRS).

Channel measurement purpose CSI-RS the, channel measurement is CRS in existing LTE system, and elements corresponding to at least two measurement of handover in a simultaneous data alternatively as might be used for demodulation, is designed for the purpose of channel measurement centered is connected to the semiconductor layer.. Handover in a also CSI-RS well as elements corresponding to at least two measurement of and which can also be used. CSI-RS to obtain information about a channel conditions the wireless multi transmitting only the object, unlike existing LTE CRS in system, every sub-frame is sent whenever is without. Therefore, to reduce overhead of CSI-RS CSI-RS generates a time on intermittently at (for example, periodically) transmission can be designed to..

Downlink sequence is if any data is sent in the case where a program, scheduled data transmission (dedicated) DMRS is dedicated to to terminal in is transmitted. I.e., a terminal-specific (UE-specific) RS DMRS it is also possible to have a compact design and be mobile. With a specific terminal dedicated DMRS the, corresponding terminal scheduled resource region, i.e. for the terminal corresponding time-frequency in which data is transmitted can be designed to transmission only in regions..

Figure 7 shows a a are defined in systems LTE-A also representing one example of pattern DMRS. surface thereof, and the.

Dl in which data is transmitted in Figure 7 one resource block pair (normal CP in the case of, in time 14 of OFDM symbols × 12 frequency and to subcarrier) DMRS resource is to be transmitted on exhibits and its position. The DMRS LTE-A 4 value as defined by an in system antennas port (antenna port index 7, 8, 9 and 10) can be transmission on. Different antenna port DMRS for different frequency resource (subcarrier) and/or different time resource (OFDM symbols) to fall can be distinguished from. (i.e., FDM and/or TDM manner multiple can be). Furthermore, the same time frequency resource located on for different antenna port DMRS one another orthogonal code (orthogonal code) can be partitioned from (i.e., CDM manner multiple can be). Group 1 of Figure 7 in an example DMRS CDM (RE) element resource represented by the antenna port DMRS for 7 and 8 can be situated in, these orthogonal codes can be of multiplexed. Similarly, group 2 of Figure 7 in an example DMRS represented by resource elements for the antenna port 9 and 10 can be situated in DMRS, these orthogonal codes can be of multiplexed.

DMRS base station option should be, the applied data precoding is the same precoding DMRS to 2000. Therefore, terminal DMRS (or terminal-specific RS) is estimated using the channel information is a pre-coding method for CDMA. The estimated through DMRS terminal with pre-coded by using channel information the, for demodulating the received data on the can be to easily test the channel unit capacity. However, terminal which is applicable to, in this precoding DMRS if so, the processing unit has an electro-encephalogram, with pre-coded from DMRS not and cannot a obtains channel information. Terminal, other than separate reference signal DMRS, i.e., using the aforementioned CSI-RS not with pre-coded can be a obtains channel information.

Figure 8 shows a a are defined in systems also LTE-A CSI-RS is surface indicative of exemplary pattern.

Dl in which data is transmitted in Figure 8 one resource block pair (normal CP in the case of, in time 14 of OFDM symbols × 12 frequency and to subcarrier) CSI-RS resource is to be transmitted on exhibits and its position. Any downlink sub frame CSI-RS pattern one of 8 (a) to 8 (e) also can be used. The CSI-RS LTE-A system in value as defined by an 8 port antennas (antenna port index 15, 16, 17, 18, 19, 20, 21 and 22) can be transmission on. Different antenna port CSI-RS for different frequency resource (subcarrier) and/or different time resource (OFDM symbols) to fall can be distinguished from. (i.e., FDM and/or TDM manner multiple can be). Furthermore, the same time frequency resource located on for different antenna port CSI-RS one another orthogonal code (orthogonal code) can be partitioned from (i.e., CDM manner multiple can be). Also 8 (a) 1 group CSI-RS CDM in an example of resource represented by (RE) element for the antenna port CSI-RS 15 and 16 can be situated in, these orthogonal codes can be of multiplexed. Also 8 (a) 2 group CSI-RS CDM in an example of resource elements represented by 17 and 18 to the antenna port CSI-RS can be situated in, these orthogonal codes can be of multiplexed. Also 8 (a) that is represented as 3 group CSI-RS CDM in an example of resource elements for the antenna port 19 and 20 can be situated in CSI-RS, these orthogonal codes can be of multiplexed. 4 group CSI-RS CDM in an example of 8 (a) also represented by resource elements CSI-RS to the antenna port 22 and 21 can be situated in, these orthogonal codes can be of multiplexed. Also 8 (a) in the same described based on the principle is also can be applied to the 8 (e) to 8 (b).

RS of patterns are also 6 to 8 and there has exemplary only, various in the embodiment of the present invention by applying a specific RS pattern is not limited to. I.e., also 6 to 8 and other RS defining and using pattern even if various in the embodiment of the present invention can be uses the are.

CSI-RS received, the terminal through CQI as a result determining the channel, and/or PMI RI (Rank Indicator) and a base station to which it is information such as. may be capable of reporting. The present in the document CQI, a mean RI PMI and described but where, CQI the them them (or CSI) can be referred to. Furthermore, said CSI-RS related to as information cell-specific information, cell a terminal within a can be applied in common to.. Furthermore, transmission period setting CSI-RS CSI-RS offset and can be designated as purpose : (configuration). For example, 0 as refers to transmission in the upstream channel transmit power of CSI-RS CSI-RS setting (configuration) and 0 is indicative of transmission power transmission in the upstream channel connecting the unhinged (non-zero) CSI-RS CSI-RS representing a separate respect to transmission period setting (configuration) CSI-RS. can be established and offset.

PDSCH will be transmitted to some embodiments, may further unlike CRS transmitted sub frame, they transmit only at sub-frame some CSI-RS to to be set up. For example, to the upper hierarchy by sub frame set for firmly supporting a CSI C_CSI,0 and C_CSI,1. can be established. CSI reference resource (i.e., CSI computational criteria are a predetermined resource region) the C_CSI,0 or C_CSI,1 can be belonging to one, C_CSI,0 and C_CSI,1 belonging simultaneously all of may be not. The, sub frame set for firmly supporting a CSI C_CSI,0 and C_CSI,1 by to the upper hierarchy is when set, terminal CSI sub-frame which do not belong any place with set present sub-frame CSI reference resource manager allows access to the trigger (or CSI computations indication) receives to minimal adjustments are always large enough expected.

Furthermore, effective resource reference CSI dl sequence is to be set up in. Effective a variety of downlink subframes subframe the glass fixing unit has a can be set as. One of its requirements, in the case of reporting CSI periodically, respect to terminal if is set periodically CSI sub frame set for firmly supporting a connected reporting CSI CSI a (link), belonging to the set of input sub-frame will sub-frames, as is.

Furthermore, CSI reference source, then, the terminal home consider the index may derive CQI (details reference the 3GPP TS 36.213 lubricious):

I.e., dedicated (dedicated) RRC using signaling information on an establishment CSI-RS in the cell may be provided to the second computer terminals. For example, initial access terminal handover or the base over center pixel block having a predetermined size in (establish) establishing (connection), the content of the base station to terminal RRC (configuration) setting CSI-RS the via signaling can be to terminal unit. To the terminal or base station based on measuring CSI-RS which require state feedback channel RRC when to transport signaling messages, corresponding RRC signaling through the message is provided to inform the terminal of corresponding parameters (configuration) setting CSI-RS..

On the other hand, the presence of CSI-RS time position, i.e., cell-specific sub-frame setting period and cell-specific sub-frame offset, for example, next table may organize his or her, such as 1.

Channel state information (CSI)

MIMO scheme, closed-loop method and (open-loop)-loop two (closed-loop) .can be distinguished from manner. MIMO-loop two MIMO scheme from receiving end at a sending end without for feeding back channel state information as in preparation of performing a transfer, meaning that the MIMO.. MIMO scheme, closed-loop MIMO channel state information from receiving end at a sending end is fed back in preparation of performing a transfer, meaning that the MIMO.. MIMO, closed-loop MIMO method (multiplexing gain) gain multiplexing of transmit antennas, in order to obtain the reference quantity received each of the plurality of sectors includes receiving end based on channel state information can be beamforming. Receiving end (for example, terminal) feedback information for the channel state can be transmitting end (for example, base station) the receiving end (for example, terminal) to uplink control channel or a up-stream like is. can assign link sharing channel.

CRS terminal CSI-RS and/or a link channel is downward using estimation and/or measure an can be. To offer channel state information is fed back to base station (CSI) has rank indicator (RI), precoding matrix index (PMI) and channel quality pointer may comprise an (CQI).

RI is information for a channel. Channel of ranks in one memory device a same time-frequency over point-to-multipoint resources downloads different sets of information for the a layer which can send (or stream) mixture by the addition of an initiator a not more than a predetermined maximum number. Rank value channel for a long time since is principally determined by fading (long term), PMI CQI and generally compared to longer provided to prevent the increase of load (i.e., less frequently) can be feedback.

Damage has PMI precoding matrix used in the transmissions from information about the is, spatial characteristics of channel identifies a source data item, a value. Precoding acids to epoxygenated fatty acids therein transmission layer transmit antennas to map meaning that it, precoding matrix layer-antenna mapping relationship can be determined. PMI has is installed to enclose and heat the noise and interference ratio (Signal-to-Interference plus Noise Ratio; SINR) (metric) measurements such as' preferred technique, an terminal based on the base station (preferred). corresponding to index precoding matrices. Precoding of information to enable a reduction in power-feedback overhead, different receiving end received including precoding matrix to be a shared predetermined code books, precoding matrix specific corresponding codebook indicating that the index/indices that only a feedback can be scheme is used. For example, reported RI PMI determines the most recently can be determined based on.

CQI a channel quality or channel is information representing the intensity. MCS a predetermined CQI combination can be expressed as. I.e., are fed back CQI index a corresponding one of the modulator exhibits and (code rate) code rate and (modulation scheme) method. CQI detects the special resource region (for example, effective subframes of sub-and/or physical resource blocks specified by the region) to set the resource reference CQI a, corresponding reference source CQI PDSCH transmission there is assumed to the, predetermined error probability (for example, 0.1) PDSCH is received without exceeding and assumed a case where the device can be can be calculated. Generally, CQI has a base station is using PMI spatial channels obtainable-SINR identifies a source data item, a received and is. For example, reported recently determines the most CQI RI PMI and/or can be calculated based on.

System for supporting the extended antenna configuration (for example, LTE-A system) using MIMO (MU-MIMO)-multi-user in for generation of additional multi-user demultiplex symbols allows for of wet liquid to flow down. MU-MIMO method antenna region (domain) between a terminal for a multiplexed formed through interfering channel, multi-user one of the feedback terminal information channel conditions downlink transmission using at a base station sector in the case of other terminals respect to second correlation value is generated due to., it is necessary. Therefore, subsequent heat treatment is performed after each order are correct operation MU-MIMO single user-MIMO (SU-MIMO) spaces are collected in the coefficient a higher accuracy should is fed back channel state information.

And more accurate measuring and channel state information may be capable of reporting to, existing RI, a CQI CSI PMI and a new CSI feedback the room can be applied. For example, the feedback receiving end for pre-coding information is PMI of 2 (for example, i2 and i1) combination of can be dictated by. Is larger than fine PMI can be feedback, such fine PMI CQI get more exquisite based on can be and reporting is calculated.

While, periodically-has CSI PUCCH or is transmitted over a, PUSCH-periodically can be transmitted over a. Furthermore, RI, number 1 PMI (for example, W1), number 2 PMI (for example, W2), which in the feedback it becomes and CQI, are fed back PMI CQI and/or relates to a wide band (WB) (SB) subband or is subtracted from to, reporting modes are defined for various can be.

CQI calculated

Hereinafter when the downlink in the terminal receiving end the assumed CQI. specifically, calculation. However, mainly the downlink transceiving, a name, an address and described in the present invention as same repeater is adaptable to be..

For reporting the CSI terminal calculates a CQI when the resources basis (hereinafter in, wire bonding and molding processes by using resource reference (reference resource)) and counts the defined setting/of relates to. First, CQI definition of. specifically, relative to.

Reporting terminal CQI. corresponds to a value of index detects the special. A modulator corresponding on a channel condition index CQI method, code rate, representative of value. For example, and its analysis indexes CQI the following table can be given such as a 2.

Which is not restricted in time and frequency based observation, terminal uplink sub-frame n each reported in respect to value CQI CQI of said table 2 index a predetermined 15 to 1 the highest the glass fixing unit has a can be the index CQI. Predetermined requirements make, corresponding to index CQI corresponding modulation scheme (for example, MCS) and transmission block size and which has (TBS), CQI reference resources are: services are represented group of downlink physical resource blocks PDSCH a single transport block is 0.1 (i.e., 10%) probability of error without exceeding in the transmission block it that can be received can be defined. Also said 1 index CQI if the glass fixing unit has a terminal if the output voltage is not able to determine the CQI index 0.

9 transfer mode (maximum by corresponding to transmission layer 8) in the case of mode for feedback reporting and, based solely on CSI-RS terminal in the uplink sub-frame n CQI being reported for calculating a representative value can be channel measurement for a. Other reporting and a corresponding transfer mode in the case of modes, terminal for calculating based on CRS CQI can be channel measurement for a.

When both bullet resistant and that meets requirements are below, the combination of block size and transmission modulation scheme CQI one. can correspond to index. Associated transport block size according to inputted CQI reference resource for a transmit on PDSCH said for can be signaling combination, the content of the modulation scheme are directed by index CQI, and, a combination of transport block size and modulation scheme if applied to a to said reference resource, corresponding CQI indicated by the index valid channel maximally close to code rate is code rate on. corresponding to requirements. If transport block size and the content of the one or more combinations of modulation scheme 2 CQI index indicated by the code rate when the close to about the same extent as the to, transport block sizes combinations can be determined.

CQI reference resource is defined as follows.

In the frequency domain CQI reference resource, derived CQI value, a which are associated into a group of downlink physical resource blocks is defined.

CQI reference resource in a time domain, single downlink subframes nCQI_ref-n is defined by. Wherein, in the case of reporting CQI periodically, the 4 nCQI_ref value less is the most or higher than the floor passing velocity while, downlink subframes nCQI_ref-n dl is valid to a value that corresponding sub-frame is determined. Non-periodic CQI in the case of reporting, for uplink has nCQI_ref DCI format (i.e., uplink scheduling control information the service provider entity and for providing terminal PDCCH DCI format) corresponding to request CQI in (or CQI request was received) dl effective the same sub-frame CQI frame is downlink subframes is determined resource reference. Furthermore, non-periodic CQI in the case of reporting, the 4 and downlink subframes nCQI_ref n-nCQI_ref has a valid downlink subframes each corresponding to, wherein any nCQI_ref-n downlink subframes [...] CQI in (random access response grant) corresponding to the request (or CQI request was received) .can be received at after sub-frame. Wherein, effective downlink subframes acids to epoxygenated fatty acids therein, corresponding downlink respect to terminal " is set in the sub frames, except for a 9 transfer mode which is not the sub-frame MBSFN, length of DwPTS 7680*Ts hereinafter (Ts=1 / (15000×2048) seconds) if the containing as field DwPTS, and, a terminal is provided in which corresponding measurement set downlink which do not belong gap. sub-frames. For resource reference CQI if a valid downlink subframes when the head cannot reach a frame is, uplink sub-frame n in reporting CQI. can be avoided.

CQI reference resource in the area layer, any starting point on the premise is CQI RI PMI and is defined by.

Index CQI CQI reference source terminal next to derive to assume particulars : (1) beginning of downlink subframes 3 OFDM symbols are control signaling may be used for. (2) main and changes a vestigial side band, floating and changes a vestigial side band or physical resources being utilized by on the broadcast channel has't element. (3) non-MBSFN CP has a length of a sub frame. (4) the redundancy version is 0. (5) channel measurement for CSI-RS is detected, the ratio of CSI-RS EPRE to PDSCH EPRE (Energy Per Resource Element) be signalled by to the upper hierarchy has a predetermined value. (6) transmission modes defined PDSCH data transmission technique (single antenna port transmission, transmit diversity, spatial multiplexing, such as MU-MIMO) the content of the surface is set currently terminal (may be default mode). (7) channel measurement for in the case of being employed for is CRS, in accordance with a predetermined CRS EPRE to PDSCH EPRE can be determined. CQI defined in a more specific related to reference to the 3GPP TS36.213 can be lubricious.

In short, downlink receiving end the current (for example, terminal) item detection data as failure trace data for performing calculations CQI past a particular single sub-frames to set the resource reference CQI, corresponding CQI PDSCH is transmitted from the base station in resource reference when its error probability is not larger than 10% in order to satisfy, for instance, under the condition that information, the value CQI.

CSI process

Onto the one or more terminal CSI. can be set with process. Each CSI process, for channel measurement for a resource-interference measurements CSI resources and CSI-RS can be associated (CSI-IM resource). Specifically, one CSI a desired signal process NZP CSI-RS one for measuring resources and, for the interferrometric measurement of resource for the interferometric measurement of one formed by (IMR) is defined. An independent process CSI each have a setting feedback CSI. Independent CSI establishing a feedback, feedback mode where the position of the (what kind of CSI (RI, PMI, CQI such as) under certain order common), . offset, or the like and feedback period.

Resource establishment CSI-IM onto the one or more terminal can be given. Each resource CSI-IM the setting, ZP (zero power) CSI-RS setting (i.e., ZP CSI-RS is mapped a RE a fixing position) and ZP CSI-RS sub-frame setting (i.e., ZP CSI-RS is generated (occur) the period for which a a fixing and offset) such as upper layer parameters can be are established.

Furthermore, resource establishment ZP CSI-RS onto the one or more terminal can be given. Each resource ZP CSI-RS the setting, ZP CSI-RS setting list (i.e., ZP CSI-RS for 16 bit size of bitmap information) and ZP CSI-RS sub-frame setting (i.e., ZP CSI-RS is generated the period for which a a fixing and offset) such as upper layer parameters can be are established.

Carrier merging

Prior to to illustrate the merging carrier for managing radio resources in LTE-A for introduced cell (Cell) to general outline of the first described. Uplink resource and lower link resources cell combination of. can be understood. Uplink resource wherein the essential factors and therefore increase not alone or lower link resources cell uplink resource and lower link resources can effectively be made in.. Carrier for composing links in a downwardly directed inner air curtain of lower link resources (Downlink component carrier; DL CC) upwardly into carrier for composing links in the upwardly link resources (Uplink component carrier; UL CC) can be designated. UL CC and DL CC the carrier frequency (carrier frequency) can be represented by, corresponding carrier frequency (center frequency) center frequency admission in. mixture by the addition of an initiator.

(Primary frequency) frequency primary cell operating in a primary cell (primary cell, PCell) (secondary frequency) frequency manufacturing thin pipes and operating in the secondary cell (secondary cell, SCell) to can be classification. A serving cell SCell and PCell can be the raised resist agent is dropped on (serving cell). PCell (initial connection establishment) connection setup initial the terminal connection reset process is performed when the handover of a distributing or collecting chamber the cell is indicated in process can be is PCell. I.e., merging carrier the after alcoholic beverage it will do the PCell is off-center from the associated control environment is to a cell in which the. can be understood. Terminal laterally protrude from the longitudinal grooves in and transmit PUCCH PCell can be assigned a. After the RRC (Radio Resource Control) connection between nodes consisting SCell configurable wireless resources in the mobile and further can be used to provide a. In merging carrier PCell to connect an can be refers to SCell serving cell. Merging is carrier but may RRC_CONNECTED is not set at carrier abnormally in the case of terminal that does not support the merging, PCell configured only present in a single piece serving cell. While, RRC_CONNECTED state and carrier merging is set when of the terminal, one or more serving cell were present and they, and the entire serving cell comprises SCell PCell. Carrier prunes not for mobile terminal supporting the network side, and the initial security activated after disclosure process is (initial security activation), it is able to be printed during the initial connection setup PCell one or more in addition to SCell can construct.

High merging carrier a request for higher rate meets the for a wider band is introduced can be used is techniques. Carrier merging 2 a carrier frequency having different configuration of one or more carrier (component carrier, CC) or 2 (aggregation) one or more merging of cells can be defined. Where each CC the frequency continues on a and may be, in addition may be the discontinuous

DL CC data to a plurality of downlink terminal through simultaneously received can be and monitoring a. UL CC between each DL CC and a linkage (linkage) the system to the central cache server. can be indicated by information. A system link DL CC/UL CC is fixed to or semi-statically can be constructed. Furthermore, entire system consisting of even CC N band with a specific terminal the monitoring/capable of receiving (N an interlayer) M frequency band of CC may be limited to. Carrier merging to perform various (cell-specific) cell specific parameter, terminal group specific (UE group-specific) or terminal specific (UE-specific) manner to be set up.

Cross-carrier scheduling acids to epoxygenated fatty acids therein, for example, plurality of serving cell one of the other control area of DL CC DL CC it including both downlink scheduling allocation information, or plurality of serving cell DL CC control the one of a plurality of and a link DL CC to UL CC, approval information for uplink scheduling means a including both.

Relation to cross-carrier scheduling, carrier indicator field (carrier indicator field, CIF) relates to. The PDCCH CIF that is transmitted over a DCI included in, or format (for example, 3 is defined by bit size) which the connectors may be discontinuous in or inclusion (for example, 0 is defined by bit size), when cross-carrier scheduling includes indicating is applied.. Cross-carrier scheduling does not fit in downlink scheduling assignment information when the current downlink scheduling assignment information on effective DL CC is to be transmitted. In addition the permission may uplink scheduling downlink scheduling assignment information is to be transmitted of one and a link DL CC UL CC to effective.

When cross-carrier scheduling is applied, one determines which CIF DL CC PDCCH in that is transmitted over a downlink scheduling assignment information related to indicating a CC. For example, in control area on PDCCH DL CC A DL CC C and DL CC B through dl allocation information to, i.e. is transmitted is present power control information to the PDSCH. Terminal through CIF DL CC A monitored to PDSCH of resource region and it is possible to know a CC.

CIF is contained in or PDCCH to are not included is some doubt whether semi-statically may be set, the terminal-specific higher layer drain terminal divided by m can be active.

CIF of the antenna in case that the (disabled) is deactivated, the same receives an specific DL CC DL CC on PDCCH on the PDSCH, UL CC linked to specific DL CC system for allocating resources PUSCH can be on. In this case, existing PDCCH which is identical to the structure a coding scheme, CCE based resource mapping, DCI format can be applied and the like.

While, when CIF is activated (enabled), specific DL CC PDCCH on a plurality of merged CC CIF among PDSCH/PUSCH on DL/UL CC one has can be for speculatively executing an instruction loop. In this case, existing PDCCH DCI CIF format can be further define the is, fixed 3 being defined or fields of bit length, regardless size format DCI CIF position may be fixed. Even in this case, existing PDCCH which is identical to the structure a coding scheme, CCE based resource mapping, DCI format can be applied and the like.

CIF even in the presence of, the base station to be doped into the wafer PDCCH DL CC can be allocating a set of. The, terminal for body of decoding may burden is reduced. PDCCH monitoring CC set the entire merged DL CC detection of the terminal portion of the PDCCH CC corresponding/decoding can be performed only in set. I.e., terminal to schedule PDSCH/PUSCH respect to, the base station a PDCCH PDCCH CC initiator can be they transmit only at on the set. PDCCH monitoring DL CC set terminal-specific or terminal group-specific or cell-specific. may be set. For example, when 3 of which incorporates DL CC, PDCCH is DL CC A DL CC monitoring can be set to. When is deactivated CIF, each DL CC on the PDCCH DL CC A PDSCH only can schedule in. While, DL CC A CIF is activated on the PDCCH in the well as to other DL CC DL CC A also can schedule PDSCH. CC monitoring PDCCH is DL CC A DL CC B DL CC C and when the is set to the PDCCH may be is not.

QCL (Quasi Co-location)

QC or QCL (Quasi Co-Located) for a signal that relationship in one aspect the for of weakness or channel aspect may be described.

One antenna characteristics large scale of signals received over the port and a sealing surface (large scale properties) on the other antenna port (infer) personalized based on a signal transmitted from the, these two antenna port is is QCL can be is said to have been cut out. Wherein, electromagnetic interference suppressing large-scale signal, delay spread (delay spread), Doppler shift (Doppler shift), frequency shift (frequency shift), average reception power (average received power), at least one of reception timing (received timing) may include a.

Or, one antenna on the port symbols are transmitted large-scale having a different property antenna on the port symbols are transmitted from the characteristic of the a conclusion on the, these two antenna port is is QCL can be is said to have been cut out. Wherein, electromagnetic interference suppressing large-scale channel delay spread (delay spread), the Doppler spread (Doppler spread), Doppler shift (Doppler shift), average gain (average gain), and a mean or average delay at least one of (average delay) may include a.

In the present invention QC or QCL is in operational use of the term, a signal described on definition of aspect or channel aspect does not distinguish between.

Terminal to the latitude and the longitude of the QCL in assumption between antenna port satisfied at a, actually two antennas port is not aired even co-located co-located to be capable of assuming.. For example, home QCL terminal ports two antennas is satisfied at a the same transmission point (TP) suspected of being present in the. capable of assuming.

For example, specific CSI-RS antenna port and, specific downlink DMRS antenna port and, specific CRS antenna port is QCL to be to be set up. The, specific CSI-RS antenna port and, specific downlink DMRS antenna port and, specific CRS antenna port (serving-cell) from one serving cell can be if.

Furthermore, antenna port is downlink and antenna port CSI-RS DMRS QCL to be. may be set. For example, plurality of TP data is reflected to a CoMP in situations, any CSI-RS antenna port is actually does a transmitted from any TP explicitly to terminal are not known. In this case, specific CSI-RS QCL is antenna port DMRS and a specific antenna port is can be order to check. the specific CSI-RS DMRS and a specific antenna port from a TP one a certain antenna port is the case may be.

This case, terminal CRS or CSI-RS obtained channel large-scale characteristic information using, through of a channel estimate of a DMRS can be performance. For example, of the estimated channel CSI-RS through using delay spread, to suppress interferences of the channel estimated from a DMRS such as operate securely.

For example, delay spread and Doppler to diffusion, any one terminal-latency-of electric power to the antenna port (power-delay-profile) profile, delay spread and Doppler spectrum, the Doppler spread estimation result, which, other antenna port used in the channel estimation for a Weiner filter (Wiener filter) or the like can be uses the. Furthermore, frequency shift and a receiving timing respect to, terminal antenna port any one time and frequency synchronization after having performed (synchronization), identical synchronisation the other antenna port demodulator of. can be applied to. Furthermore, average reception power respect to, terminal two or more antennas ports 2 references signal received power (reference signal received power; RSRP) can be averages the measuring.

For example, terminal Enhanced-PDCCH (EPDCCH) or PDCCH associated DL based DMRS a DCI (DMRS-based DL-related DCI format) format through scheduling DL. capable of receiving information. In this case, in a terminal through the sequence DMRS corresponding scheduled PDSCH channel estimation for a performing performs demodulation data. For example, folded in such a manner that the terminal if DMRS DL scheduling information received from specific for setting port RS (for example, specific CSI-RS, specific CRS, or its DL CRS serving cell, such as) port and QCL if can be assumed to be, to test the corresponding devices by terminal in channel estimation through port DMRS said specific RS of ports such as delay spread the users determine a structure of basic estimated from large-scale characteristics received-based DMRS through applying estimate steps can enhance the performance of the..

The, the CRS or CSI-RS a printed circuit board in the frequency domain transmitted cell-specific since, terminal-specific transmission in the upstream channel DMRS greater than the large-scale channel compared to correctly recognize the. since. In particular, before sub frame every has CRS reduced from the rear wave ratio over the bandwidth that is also broadcast at a higher density to because the reference signal, generally channel large-scale characteristic thereof CRS estimate stably producing from a. obtain more accurate. While the particular scheduling has DMRS RB channel is a vertical direction of a vehicle-specific terminal only large-scale characteristics estimate for a signal with accuracy is. separated than CSI-RS or CRS. Furthermore, a plurality of terminal PRBG even as if the mobile station was schedule. Base station used to transmit a precoding matrix a physical resource block grouping unit (PRBG) to terminal processor can change on the effective channel received PBRG unit can be changed. Therefore, broader band over based DMRS even for estimating the characteristics channel head gimbal can be working cylinder is inserted into the same.

On the other hand, terminal is not QCL (non-quasi-co-located; NQC) antenna port for to (AP), for large scale point in the same corresponding AP having channel characteristics can't assume notably. In this case terminal timing acquiring and tracking (timing acquisition and tracking), frequency offset estimation and compensation (frequency offset estimation and compensation), (delay estimation) delay estimates, and Doppler estimation (Doppler estimation) NQC AP according optical axis to form lights must independently processes the data sets.

Collaborative multi-point (Coordinated Multi-Point: CoMP)

System performance improved system 3GPP LTE-A according to requirements, CoMP transmitting/receiving techniques (co-MIMO, cavity (collaborative) MIMO or network MIMO steps is on) is proposed. CoMP (cell-edge)-bounded cell technique and enhances the performance of the terminal the average and which has sector (throughput) can be increase the yield.

Generally, as a frequency reuse factor (frequency reuse factor) is 1 in multi-cell condition, inter-cell interference (Inter-Cell Interference; ICI) due to cell-disposed at the boundary between a wire yield sector data voltages and the mean performance of the terminal can be reduced. To reduce such ICI, existing LTE system via power control terminal specific a fractional frequency reuse (fractional frequency reuse; FFR), such a simple passive interference by using techniques restricted by the cell-having an environment in which a terminal disposed at the boundary between a wire that is suitable for yield method low performance been is applied. However, rather than lower the resource usage frequency per cell, to the terminal ICI reduce or a ICI the desired signal reuse as can be and it is more preferred to set. Then a certain amount to achieve, is data transmission technique CoMP can be applied.

In the case of downlink CoMP technique which can be applied preferably the electroless joint-processing (joint processing; JP) technique and adjusting scheduling/beamforming (coordinated scheduling/beamforming; CS/CB) can be classification technique.

Each point of the unit collaborative CoMP JP mirror transistor (base station) can be using data in. Collaborative CoMP cooperative tranmission unit base station used in the set of.. A joint technique JP transmission (Joint Transmission) technique and dynamic cell selection (Dynamic cell selection) can be classification technique.

The data transmission technique joint, PDSCH plurality of point at a time (some or all of unit collaborative CoMP) transmitted from circulation promoted. a technique. I.e., data sent to a terminal single a plurality of transfer point can be sent simultaneously from. According to data transmission technique joint, coherently (coherently) or non-coherently (non-coherently) quality of a received signal, either can be improved and, in addition, other terminals actively interference with respect to a may erase.

Dynamic cell selection mirror transistor, PDSCH (in units of collaborative CoMP) at a time transmitted from one point circulation promoted. a technique. I.e., single at any particular time the data is transmitted and transmitted from one point, the point of time are recorded in the point the other devices in the unit assists in substantially corresponding terminal data transport for the since a current from a battery, corresponding terminal transferring the data to the data storage point can be selected dynamically.

While, collaborative CoMP surface allocated to respective CS/CB a single unit of data transmission for the terminal cooperatively beamforming can be. Wherein, but only (serving-cell) serving cell data, multi-user scheduling/beamforming to test the corresponding devices by CoMP collaborative unit by adjustment of cells can be determined.

While, in the case of uplink, geographic reception point multi-(coordinated) adjusting the spaced apart plurality of points adjustment of link based on the signals that are transmitted by the means a. Uplink which can be applied in the case of a joint received CoMP technique (Joint Reception; JR) and controlling scheduling/beamforming (coordinated scheduling/beamforming; CS/CB) in can be classification.

JR mirror transistor is a signal transmitted via the transmission PUSCH plurality of received involve received at point, only one point is PUSCH CS/CB mirror transistor received the beamforming/multi-user scheduling but CoMP collaborative unit by adjusting of cells are calculate on the..

CoMP provided using such, a multi-terminal (Multi-cell base station) cell base station supporting data jointly from the item may be. Furthermore, each base station the same radio frequency resources (Same Radio Frequency Resource) terminal one or more by the explosive force of the air simultaneously supporting the objective compound.. Furthermore, between a base station and a terminal the base station based on the channel state information of space division multiple access (Space Division Multiple Access: SDMA) may perform a method.

CoMP open service base station and one or more cooperative base station are through (Backbone Network) to distribute the scheduler is connected to (scheduler). A scheduler, each base station through to distribute the measured terminal and cooperative base between on a channel state or a radio channel information about the. is fed back. For example, scheduler the serving base station and one or more cooperative base the stations for operation cooperative MIMO can schedule information. I.e., each scheduler MIMO cooperative base station indication of operation. a H level is reduced directly.

CoMP system as described above a plurality of cells bound group operates virtual MIMO system can be position of a reflector according to each, basically using multiple antenna MIMO techniques are of manufacturing can be applied.

CoMP and CSI process

Figure 10 shows a downlink also representing exemplary operation CoMP. surface thereof, and the.

ENB2 and eNB1 the UE in an example of Figure 10 is located between, two eNB UE receives an JT (Joint Transmission) to excessive interrupting problem to solve, DCS (Dynamic Cell Selection), DPB (Dynamic Point Blanking), a suitable, such as CoMP CS/CB (coordinated scheduling/beamforming) performs operation. The UE suitable for facilitating operation CoMP CSI feedback for carrying out, for each feedback CSI is eNB RI information, CQI information and PMI which information section are placed at both sides, additionally JT eNB channel information between a record access method for a system (for example eNB1 from UE channels to and eNB2 from offset information of phase relation between the channels to UE) .may be included.

Whether serving his/her in Figure 10 UE CSI in eNB1 but shown reporting feedback, according to or to report feedback CSI to eNB2, two eNB CSI to an event that both a may be loaded with feedbacks.

By a network and to determine parameters to support scheduling CoMP, UE DL (downlink) CSI as well as information of a serving eNB/TP CoMP eNB/TP DL CSI of neighboring that participate in the can be feedback together information. To this end UE different data transmission interference environments and various eNB/TP identifies a source data item, a plurality of CSI processes can be feedback for generating and CSI.

CoMP CSI at resource interference for the measuring of interference in is carried out by using an acidulous (IMR). One or more UE receive an setting IMR, IMR are each independently have a setting up by. I.e., each signal detector of IMR, sub frame offset, resource establishment (i.e., position mapping RE) independently given, this information an upper layer (for example, RRC layer) from the network may be signaled to UE.

(Desired), so that desired at CoMP CSI channel or signal for the measuring of CSI-RS is is used. Set one or more UE CSI-RS receive an, independent of each other denote one CSI-RS have a setting. I.e., each CSI-RS the transition period of, sub frame offset, resource establishment (i.e., position mapping RE), home for transmission power (i.e., parameters Pc), the display unit to highlight a number antenna port independently given, this information an upper layer (for example, RRC layer) from the network may be signaled to UE. Constitution: services are (SMR) resource signal measurement same may be.

One or more setting to UE CSI-RS in IMR and at least one, to one CSI-RS resources and, one for the interferrometric measurement of IMR associated one CSI process is (or in combination, or in combination) is defined. Different CSI CSI or induced calculated for the process information, recording a period and independent UE according to frame offset sub can be is fed back into the network from. I.e., an independent process CSI each can take the setting feedback CSI. Such resources and CSI-RS IMR associated (or in combination, or in combination) CSI and information about the feedback setting information, or the like, that has higher layer according process CSI UE from the network via signaling may be provided to. Example of Figure 10, for example, below 4 of tables, via such as UE process is CSI of 3 can be set to.

In said table 4 each CSI-RS 1 and a CSI-RS 0, eNB1 in eNB serving UE CSI-RS; receiving from the base station neighboring that participate in the cooperates with a receiving from eNB2 in eNB exhibits and CSI-RS.

Below said table 4 of the 5 of tables, via IMR exhibits setting of 3. The muting (muting) eNB1 the IMR 0 (or null packet (null) signal transmission) performs performing data transmission on has eNB2 " is set in the resource, the UE IMR 0 from the memory device stores a eNB1 eNB from. for measuring the interference for. The IMR 1 performs the muted eNB2 eNB1 has data transmission on is set to a resource performing, the UE IMR 1 from the memory device stores a eNB2 eNB from. for measuring the interference for. Both the IMR 2 eNB2 and eNB1 " is set in the resource performing muted, the UE IMR 2 from the memory device stores a eNB2 and eNB1 eNB from. for measuring the interference for.

NIB CoMP an improvement over the current state-scheme

Non-ideal network backhaul (Non-Ideal Backhaul; NIB), geographic CoMP be retained by the processes are repeated at least once for transmitting/receiving signal in a backhaul link some degree of latency to (for example, 5 to 30ms) the presence of. network. Existing CoMP CoMP operation processes are repeated at least once without delay on backhaul link performed by a routing control information an ideal state kindle designed under the assumption that, in frame units sub processes are repeated CoMP scheduling, determining a dynamically which, for example, every sub PDSCH boundary line is held for every frame is changed point transmission of dynamic point switching (DPS) technique can be supported.. For example, DPS for the purpose to support set to 10 (TM10) transfer mode to UE 2D downward into the link assignment (DL assignment) DCI format when provide, DCI 2D format specific field in bit size 2 PQI by and pointing downwards in the roll-state value, for transmitting PDSCH TP PDSCH RE for QCL between RS and mapping information to dynamically provide information can be.

However, because preexisting of NIB CoMP CoMP operation in a network applying operation present in the substrate. For example, between points participating CoMP when NIB is backhaul link of, any point is currently sub frame including DCI field PQI UE a 2D format the data information includes control information, corresponding sub frame are transferred from different points PDSCH surface or both surfaces of the Publication order scheduling information for, two prior to delay transmitting/receiving on NIB between points to predetermined scheduling said PDSCH should shared and. The dynamic point selection rather than being static according to the predefined pattern of since the close operation scheduling PDSCH, is formed on the resultant structure to support NIB CoMP of difficult to respectively carried out is present.

Therefore, in a network in the present invention NIB CoMP a correct and efficiently performing the dB stores or support. respect to.

Hereinafter (eNB) base station mainly in CoMP between but described example for example, (TP) transfer point principle of the present invention, receiving point (RP), remote radio head (remote radio head; RRH), (relay) repeater can be applied even CoMP between. I.e., base station, TP, RP, RRH, at least one of the other relay the term that is representative terms should understood.

Furthermore, in a message based on hereinafter 3GPP LTE but also disclosed to the present invention, based on another technique principle of the present invention communication system is also can be applied.

For NIB CoMP Xn-signaling information

Figure 11 shows a also CoMP is not to be applied to the situation where. plane from the also disclosed for.

TP1 and of serving cell with which UE in an example of Figure 11, the UE DL scheduling information into the robotic device such receives a plurality of electomagnetic signals from TP1, is subjected to from TP1 also PDSCH.

In situations such as exemplary of Figure 11 TP1 and TP2 is non-CoMP (non-CoMP) NIB cooperate link signaling for transmission can be exchange. Such collaborative TP the signaling for the transmission referring to link between Xn link (for example, backhaul link link/X2) in that transmitted on, may have the form of Xn-signaling. Furthermore, the signaling for the collaborative transmission, loading (loading) information, one or more CSI-RS setting information, one or more CSI-IM (or IMR) setting information, or at least one setting information DMRS may include a.

Said loading information (or congestion (congestion) information) the, specific TP is directed to the connection (i.e., a cell serving itself) information about the number of UE may comprise an. Herewith is the collector, and/or, is directed to a particular loading information said TP number of the maximum connectable UE UE the present connection based on a rate for the set of two request group information, (or percent), service the available capacity contrast specific TP the attachment data contains information that indicates spares or usage can be. Such loading information a particular TP TP Xn-signaling to the other or manner, plurality of TP to may compute Multicast/broadcast. Furthermore, specific TP TP the other, the hand of the (are) provided to the first and second loading information request may be loaded with.

One or more said CSI-RS the setting device sets the set information, NZP CSI-RS setting information of its own, and when specific TP (for example, NZP CSI-RS RE position, period, offset or the like) and/or its ZP CSI-RS setting information (for example, position ZP CSI-RS RE, period, offset or the like) may include a. One or a plurality of setting information said NZP CSI-RS NZP CSI-RS setting and it is possible, , a at this is actually said TP to NZP CSI-RS and it is possible, , or certain UE to NZP CSI-RS set to it is possible,. Furthermore, one or a plurality of setting information said ZP CSI-RS ZP CSI-RS setting and it is possible, , applied match rate the PDSCH may ZP CSI-RS setting information. Such an at least one a particular setting information CSI-RS TP TP Xn-signaling to the other or manner, plurality of TP to may compute Multicast/broadcast. Furthermore, specific TP TP (are) the other, the hand of the one or more the first and second to CSI-RS request provided setting information may be loaded with.

One or more said CSI-IM (or IMR) the setting device sets the set information, one or more specific TP CSI-IM setting information (for example, position ZP CSI-RS RE, period, offset or the like) and/or for each setting of the RE CSI-IM said position whether to perform a specific TP is muted information about the (or whether transmission) may comprise an. CSI-RS the setting device sets the set information of said specific TP, specific TP (are) set by to a particular UE CSI-IM setting information, said specific TP UE (are) associated to a (associate) does not setting to a low cost (are) adjacent TP UE of setting to signal and informs CSI UE (are) of the specific/creation calculated for supplying environment interference CSI-IM setting information (for example, position ZP CSI-RS RE, period, offset or the like) such as may include a. Such an at least one a particular setting information CSI-IM TP TP Xn-signaling to the other or manner, plurality of TP to may compute Multicast/broadcast. Furthermore, specific TP TP (are) the other, the hand of the one or more the first and second to CSI-IM request provided setting information may be loaded with. Furthermore, specific TP TP (are) specifying the other, the hand of the corresponding setting of CSI-IM RE [...] position request (request to execute at or transmission) may be loaded with.

Said DMRS the setting device sets the set information, set in the quartz carrier part transmission CoMP TP in each according UE PDSCH transmits the applicable when DMRS setting (for example, (sequence scrambling initialization parameter) initialization parameters scrambling sequence DMRS) information of a previously TP exchanged between the a Xn-signaling is supported, it is necessary that. For example, each other TP1 and TP2 UE the corresponding to a time interval for PDSCH transmission CoMP in situations, TP2 is read from stored information to UE PDSCH transmission DMRS setting information formed by the same, TP1 to TP2 is Xn-signaling should inform through an. Are used to irradiate, TP1 is UE DMRS to RRC setting information via signaling corresponding should inform the PDSCH is UE may be performing correctly reception, TP1 and TP2/ending signal (latency) than Xn-signaling between RRC signaling to UE from TP1 is larger latency is since. Therefore, the TP1 TP2 and receives from TP2 DMRS of RRC signaling UE setting information to identified surface, is depending on a setting DMRS UE of the TP2 from the TP2 can be receiving and correctly PDSCH.

Wherein, a plurality of setting information to specific CSI-IM TP including network (for example, cluster CoMP)-unique within the (unique) should directed on. I.e., specific intended for TP1 CSI-IM received information indicative of setting in TP2, from information corresponding TP1 CSI-IM intended for setting what R in order to plurality of TP CSI-IM CSI-IM any between any containing setting information for setting is directed to whether should is predefined. Therefore, in the present invention network-wise (network-wise) CSI-IM setting information (hereinafter, NW-CSI-IM setting information) for defining a.. For example, the setting device sets the set information NW-CSI-IM, each CSI-IM NW-CSI-IM the setting index (or NW-CSI-IM setting index) in case that the file can be defined by, Xn-signaling between TP NW-CSI-IM in the form of the item may be an effect on the promotion of normal setting information.

For example, of 3 one eNB CoMP cluster is formed in and located in, in this case total M of index is NW-CSI-IM can be defined. For example, such as of below 6 of tables, via M=7 may be index is NW-CSI-IM.

Said table 6 such as exemplary, NW-CSI-IM the setting device sets the set information in the present invention to propose, specific eNB for directly whether muting according as information indicative of may be loaded with.

Furthermore, said table 6 and there has only exemplary, and the life of the lamp is items display is non-muting transmission power level may be subdivided into, in this case being set at a higher value than the M 7 may be. Such various interference hypothesis (interference hypothesis) by considering NW-CSI-IM setting information when defined, M value being set at a higher value than 7 may be. Or each eNB [...] of all case without taking into account the only a portion defining would be, M value set to a low value than 7 may be.

Furthermore, each setting information whether muting of eNB NW-CSI-IM (non-muting in the case of power level) indicative of a particular additional operation of eNB (behavior) indicative of the independent even and what may be loaded with. For example, the setting device sets the set information NW-CSI-IM CoMP according eNB each in "muting," "non-muting," or "don ' t care" directed to may be defined. For example, said table 6 of example 7 of tables, via down additional NW-CSI-IM index 8, such as containing setting information for NW-CSI-IM may be defined.

I.e., in operation resource for a corresponding eNB2 NW-CSI-IM NW-CSI-IM index 8 "don ' t care" may be set to, this muting eNB2 is read from stored information for to perform a surge resource NW-CSI-IM, for to perform a non-muting, precoding and any even non-muting or any power allocation is applied a signal is transmitted whether eNB2, or the like, that has the torsion bar is used for optionally crystalline is a. Therefore, other eNB are (for example, eNB3 and eNB1) in any resource NW-CSI-IM the eNB2 is read from stored information the whether take an action if the expected, eNB2 that contains interference caused by not capable to ensure that constant..

As exemplary said, individual eNB of operation resource for a specific CSI-IM a explicitly indicates hypothesis Xn-signaling format (for example, backhaul signaling format) and are designed, the setting information CSI-IM eNB between. can be exchanged. For example, each the NW-CSI-IM index, respect to each eNB {muting, predetermined maximum or minimum power level value, specific precoding information (for example, beam direction, precoding coefficient, or precoding set information), "don ' t care"} comprised of at least one element of the set of for explicitly directed to and represented to multiple columns is fixed, , using specific NW-CSI-IM index be signaling backhaul.

Furthermore, between signaling said NW-CSI-IM eNB the setting device sets the set information may be using, to inform a UE is eNB CoMP information as information regarding hypothesis may be using. For example, which are connected to it eNB1 UE such as RRC to a higher layer at a signal at said NW-CSI-IM index 1, 2, 3, 4 (or all) is able to set the a.. For example, her CoMP UE1 eNB1 to which are connected said NW-CSI-IM index 4 (reflect interference environments non-CoMP) and NW-CSI-IM index 2 (eNB2 is a muting CoMP reflect environment) RRC indexes NW-CSI-IM of two may be set by, CSI NW-CSI-IM index 2 and 4 connected with the air suction port by is supplied to process, different CoMP hypothesis (for example, different interference environments) based on eNB1 and/creation calculates CSI CoMP UE1 is a saturation using an integrator feedback loop may be loaded with. For example, to corresponding CoMP UE1, csi-IM-ConfigId-r11 = 1 to the NW-CSI-IM index 4, r11 = 2-csi-IM-ConfigId the NW-CSI-IM index 2 can be set to.

I.e., her csi-IM-ConfigId-r11 value individual UE {1, ... , R11-maxCSI-IM} in is welded to the loading but designated one, network (for example, cluster CoMP) unique network in terms the NW-CSI-IM index 1 with the (unique), ... , .Can correspond to 7.

As in still another exemplary, a connected with itself the eNB2 UE such as RRC to a higher layer at a signal at said NW-CSI-IM index 1, 2, 5, 6 (or all), could of operation is set to a, corresponding UE each NW-CSI-IM index corresponding to the taking into account the different CoMP CSI calculates the feedback can be.

Said CSI-IM mainly hi exemplary network information indicative of setting to be-wise but also disclosed to, NZP CSI-RS this principle even for setting information ZP CSI-RS or setting information can be applied. I.e., including a plurality of eNB specific scale network (for example, cluster CoMP) in, NW-NZP-CSI-RS setting information (or NW-NZP-CSI-RS index) and/or NW-ZP-CSI-RS setting information (or NW-ZP-CSI-RS index) by defining a, specific NW-NZP-CSI-RS setting and/or in particular NW-ZP-CSI-RS eNB are in the network setting (in addition, corresponding eNB UE are a served by a) unique (unique) may be referred to the..

Furthermore, CSI-IM setting information indicative of the general outline to be-wise network, even for CSI process setting information can be applied. For example, one CSI NZP CSI-RS index and the index process (one) combination CSI-IM index (one) can be defined. I.e., including a plurality of eNB specific scale network (for example, cluster CoMP) in, NW-CSI-process setting information (or NW-CSI-process index) by defining a, specific NW-CSI-process eNB are in the network setting (in addition, corresponding eNB UE are a served by a) unique (unique) may be referred to the..

The aforementioned loading information, one or more CSI-RS setting information, one or more CSI-IM (or IMR) setting information, or DMRS the setting device sets the set information, CoMP Xn-signaling between TP that participate in the in advance such as exchange (or, periodically) can be is information must. I.e., NIB CoMP TP that participate in the operation between such a information must exchange in advance such as Xn-signaling, Xn-signaling delay (for example, on the order of several tens of ms) when even CoMP disclosure operation whether any conditions (for example, TP1 for loading situation has a trapezoid form if there is the muted such as performing TP1) to determine the, use can be made of, as a basis.

Furthermore, said loading information, one or more CSI-RS setting information, one or more CSI-IM (or IMR) setting information, or DMRS the setting device sets the set information, used only for operation CoMP do not limited to, using NAICS (Network-Assisted Interference Cancellation and Suppression) to support operation of terminal another payload such as the use can be-electromagnetic uses.

SSPM Xn-signaling scheme for technique

Also Figure 12 shows a SSPM is surface to explain the technique.

For NIB CoMP TP as a technique using Xn-signaling between, semi-static point muting (Semi-Static Point Muting; SSPM) techniques are can be applied. SSPM hereinafter in that are in consideration additionally in the case of Xn-signaling. also disclosed for features.

SSPM a particular TP (for example, serving TP1) only sends a PDSCH, adjacent TP (are) the predetermined period of time during predetermined bands, to manner in which a driver performs an is muted. TP muted is (are) performing information about the and band for an interval of time which TP Xn-signaling between can be appointment through an. Specific set consisting of plural pixels adjacent to adjacent specific band (are) transmitted TP SSPM according to technique that do not develop, CoMP UE TP interference from adjacent with the latitude and the longitude of the circuit board is installed inside (are) are transferred from serving TP PDSCH receiving. can be maximised performance.

SSPM disclosure 1-way Xn-signaling scheme for

SSPM one direction for a particular Xn-signaling TP (1-way) broadcast for (or one or more other TP to unicast or Multicast) is defined that can be.

At this time Xn-signaling TP for transmitting according to which information is provided, "specific time interval" during "specific band" TP or other serving the to (are) are performed to execute at muted is a (or a promise) can be message.

Wherein, "specific time interval" predetermined unit (for example, sub-frame) is represented by or a value which. Furthermore, the "specific time interval" TP to do and muted from fabric based time begins when time information to indicating whether that's all for (for example, sub-frame bitmap are configured in the form of the, continuous or discontinuous time information) may be represented by. Furthermore, the first and second sub-frame bitmap form in addition to the what point the (for example, such as particular sub-index) corresponding from disclosure is "specific time interval" is whether may explicitly indicated, said sub-frame bitmap is few-time air after what point the (for example, such as particular sub-index) to the completion of the whether in "specific time interval" may be loaded with explicitly indicated.

Such "specific time interval" to depart for CoMP operation (such as muting/non-muting) sheet when the recording sheet is conveyed (or the start of) frame number (frame number) (for example, a system frame number (SFN)) may be used. For example, SFN Xn-signaling included in a wireless frame are selectively instructed are specified CoMP an operation is to be applied to is able to indicate having. The frame number (for example, SFN) for transmitting the Xn-signaling TP timing of-base can be defined. Or, Xn-signaling TP receiving a Xn-signaling information about the timing of TP for transmitting when the know, Xn-signaling TP said SFN value based on timing of receiving a decides to a value that may be loaded with.

Furthermore, "specific band" unit a predetermined frequency (for example, unit RB) is represented by or a value which.

SSPM disclosure 2-way Xn-signaling scheme for

SSPM is TP1 to TP2 for the Xn-signaling the muted (i.e., resource arbitration (resource coordination)) will be provided to a requesting (request) and, in this regard is to respond to a TP1 TP2 of the type bi-directional (2-way) signaling can be defined. At this time, a reply message transmitted by a TP1 TP2 and other TP (for example, TP3, TP4, ...) Multicast/broadcast ointment, drink or injection may be manner, TP and other TP1 or TP2 is (are) to individually unicast manner may be loaded with.

At this time TP1 transmit the information is included in a message to a request, "specific time interval" during TP2 is muted "specific band" to a message request performing can be.

Furthermore, "specific time interval" and the "specific band", the illustrated room for said SSPM 1-way Xn-signaling uses the option associated with the region is chosen can be.

TP1 in an example said request for sending a message "certain conditions" can be defined, and a..

For example, a (associate) associated is TP1 UE CSI plurality of pre-each to RRC signaling units so that the processes are performed (RRC signaling 100ms or more delay can be generated the assumed to) input by a user through set, each CSI the feedback symbols for the process continues receiving differing CSI processes difference CQI a is fed back a relative magnitude of the read signal when I above an upper, the TP1 transmits a request message can be said. Said plurality of CSI 2 process CSI and 1 process CSI process may comprise, for example, TP2 is non-muting CSI process when the NZP CSI-RS1 and 1, that reflects the combination of set to CSI-IM1, the NZP CSI-RS1 CSI process 2 when muting is TP2 and, that reflects the combination of CSI-IM2 may be proposed which are set up in such. A is fed back to 1 process CSI CSI and CQI1 2 process is fed back to a CQI2 which above an upper a relative magnitude of the read signal is, said request for the message transmission condition is met can be would.

Such "certain conditions" TP1 and TP2 between the loading information can be for considering in addition. TP2 for example for loading situation is a predetermined reference value to a sink only if said accept defined which can be. Or, TP2 for loading situation when the congested predetermined reference value, even if the delivery request said may be loaded with TP2 of declined.

Furthermore, at such "certain conditions" pre-among TP to be different priorities are established (for example TP1 the master (master) and TP2 is controlled by the slave (slave) may be preset relationship), a priority according to said is TP1 TP2 surface sends a request for the necessarily must conform to the may be defined in such a way that.

Said loading information, one or more CSI-RS setting information, one or more CSI-IM (or IMR) setting information, such as settings information and DMRS or Xn-signaling through the information exchanged in advance such as the stomach TP2 will accept the request (confirm) requirements and the preset values of work information corresponding to when previously provided to TP1, TP2 is TP1 sent to only request muting for a SSPM (i.e., without response of TP2) SSPM operation can be disclosure.

The first and second request for the message transmission certain conditions the variables are as defined in and, by corresponding the condition is satisfied from TP1 said request message is to be transmitted would be, such a request receiving a message the has TP2 may be and adapted to receive a second. As such, certain conditions connected necessarily must conform to the request for TP1 TP2 is when (or TP2 is TP1 to respond to and sends a message without when said request along the) of a conditional 1-way Xn-signaling may convey is.

SSPM in operation Xn-signaling scheme

The aforementioned 1-way or 2-way Xn-signaling through a SSPM disclosure is specific for a predetermined period of time, when at specific band, corresponding time interval is automatically in a third step SSPM is terminated defined which can be. Or, corresponding time interval is terminated before additional Xn-signaling (for example, manner 2-way manner or in a 1-way) matched with the extending of a time interval. is satisfied at a. For an interval of time which extending a form of information about the time information may be updated on, plate band information in the form of band information can also be updated on..

For example, TP2 is non-muting CSI process when the NZP CSI-RS1 and 1, that reflects the combination of set to CSI-IM1, the NZP CSI-RS1 CSI process 2 when muting is TP2 and, that reflects the combination of CSI-IM2 may be proposed which are set up in such. In this case, before the disclosure is SSPM, the TP1 CSI 1 process for scheduling based reporting feedback UE (i.e., such as on the MCS1 CQI1 set) in PDSCH transmission UE to. While, the TP1 the disclosure during a SSPM is CSI process 2 is for scheduling based reporting feedback UE (i.e., TP2 of blinking of images is equal to an effect CQI2 reflect data distributed (for example, MCS1 is higher than the in MCS) such as set to MCS2) SSPM-PDSCH to UE in. transmission. As such, to UE TP for transmitting position information in accordance with the latitude of PDSCH, CSI process 1 and 2 the feedback symbols for the reporting CSI process receives both rainwater or dust from being, a page is adjusted based on the section SSPM CSI CSI processes specific depending if the feedback based on the information scheduling to be capable of application to PDSCH.

SSPM Xn-signaling scheme for the feedback symbols for the

SSPM for an interval of time or time interval is set is to, how adjacent TP SSPM-PDSCH TP for transmitting (are) utilizing band muting of a scheduling a CoMP UE SSPM-PDSCH judges for transmitting additional Xn-signaling a feedback information for availability can be defined.

For example, SSPM (coordination) TP that participate in the adjustment is dictated by resource (for example, frequency, time, power, spatial domain one of or more domain defined by a resource) during and certain of the (for example, percent ratio) is, said UE a requires adjustment (or CoMP UE) scheduling for also that indicates that a been used (usage), feedback information is Xn-signaling TP in the form can be exchanged between. Furthermore, SSPM TP that participate in the adjustment is dictated by and certain of the resources (for example, percent ratio) is, said UE not requires adjustment (or non-CoMP UE) for scheduling been used that indicates that a TP Xn-signaling, feedback information is also in the form can be exchanged between.

Use said CoMP UE non-CoMP UE and feedback information use feedback information to transmission together Xn-signaling may be is defined. Non-CoMP UE CoMP UE use feedback information and use feedback information should be provided along, said TP blood storing chamber, and a regulating is benefit resources are dictated by UE form of a powder or an ointment (benefit) (i.e., CoMP UE) how to may be been used, then setting of resource SSPM because it can be based on is. The, adjacent TP muted is (are) performing CoMP UE corresponding time interval and band are substantially schedules various uses of these materials which designates an ice cutter cuts an availability, resource muting the second unnecessary for suppressing a drive current when a corresponding source with other UE to for data transfer for utilizing the, can be performance and entire network.

CoMP Xn-signaling scheme for a resource adjustment network architecture and

(Coordination decision) determined adjusting in in several exemplary examples of the present invention performs and controlling result (coordination result) (or resource arbitration result) to see that principal for delivering a, CoMP TP plurality of that participate in the may the acknowledgement message is one of, special that is defined center control node may (central control node; CCN). CoMP TP plurality of that participate in the controlling speed and position over a distributed if the combining is CCN (distributed coordination architecture) and the composition can be taken 2-, speed and position centric CCN a form. the composition can be taken 2 - (centralized coordination architecture). Hi in several exemplary examples of the present invention on a particular intelligibility of Xn-signaling between TP but them is, speed and position type dispersed Xn-signaling between TP of area and, of speed and position centric means Xn-signaling between TP CCN and may be loaded with.

For said SSPM Xn-signaling in a proposed room, said resource arbitration request or resource adjustment the Xn-signaling a for indicating the result, below of tables, via TP side transmitted and 8 (or sender eNB) index particular one of index NW-CSI-IM know a particular frequency-time resource unit (are) (for example, PRB units and/or sub-frame unit) pointed out in the reduced noise can be.

As in this case, 8 said table, a directed Xn-signaling NW-CSI-IM index (are) meaning of. may be interpreted as follows.

A sender for sending indicative information is NW-CSI-IM eNB is formed of a pressure sensor applying eNB interface for to (are), a notifying/resource adjustment is pointing information said NW-CSI-IM relates to result or are performed to the resource adjustment for alerting the selection of any that bit to (selector bit) can exist. For example, pointing information included in NW-CSI-IM value according to the value of a bit selector said NW-CSI-IM pointing information is information representing the result of a notifying/resource adjustment may be and interpreted as, coupled to the resource adjustment may be interpreted to. Or, a separate pointing information said NW-CSI-IM where there is no indication of a notifying/resource adjustment to interpreted to which is a client user of a (i.e., NW-CSI-IM pointing information default (default) to resource adjustment a notifying/representing the result to that count is interpreted as half information) may be loaded with defined. In this case, is pointing information NW-CSI-IM relates to request resource adjustment to indicate special should information is included in the instruction (for example, particular field for a particular value when the resource arbitration request and a page conflict request being interpreted, other in the case of both resource adjustment a notifying/may be interpreted as a result.). Or, a notifying/resource adjustment result in the case of request resource adjustment case of separate for Xn-signaling format may be the design.

NW-CSI-IM pointing information is indicative of a result when a notifying/resource adjustment

A pointing information NW-CSI-IM, listed in pointing information NW-CSI-IM NW-CSI-IM index (are) set from a received broadcast signal (time/frequency resource position) position RE eNB transmitted by a sender in (interference) signal characteristics for (for example, transmission power and/or precoding information) is, directed actually PRB and/or sub-frame index position signals transmitted by a corresponding sender eNB (for example, such as PDSCH) characteristics for and capable of assuming that a informed that he or she can be interpreted to.

The distributed mainly analysis instruction NW-CSI-IM can be applied to the structure. For example, said table 6 subscribers 7 exemplary CSI-IM one or more such as in the form of setting information (or IMR), sender eNB is "non-muting" specific NW-CSI-IM resource signal transmission in the case of, said sender eNB receives an on resources NW-CSI-IM the applied for signal characteristics, a particular frequency/time resource (resource map time frequency/or other) the applied to equal to that signal characteristics, (are) by notifying a recipient eNB. can. Such notification information for all of the e eNB other received (are) indicated in the received information UE source/time particular frequencies that the key to be scheduling, said sender eNB is connected with said a particular frequency/time resource NW-CSI-IM index processes with respect to a inform as information is based on information feedback CSI UE, downlink transmission be applied to a precoder and, such as MCS of determining or may be selected.

Furthermore, any recipient eNB multiple map resource time a particular frequency/is same to the sender of NW-CSI-IM from eNB Xn-signaling indicative information is when received, each sender eNB NW-CSI-IM a indicated in offering information is index (are) a common corresponding intersection of a particular directed NW-CSI-IM index (are) .can be determined. The, a particular directed common said NW-CSI-IM index (are) is included (are) is determined and index process CSI, said recipient the eNB, receives said CSI process index (are) set schedule for performing feedback CSI UE who has made the. can consider. I.e., for specific NW-CSI-IM index "non-muting" which are set up in such corresponding source when an apparatus are eNB applying a specific signal (for example, said table 6 subscribers 7 index NW-CSI-IM in an example of the case of 4, 6, 7), mxm eNB from receiving said NW-CSI-IM indicative information is the map for a specific time as a/frequency resource UE scheduling should be performed, in the relevant portions of the index (are) directed by UE NW-CSI-IM which is measured based on interference characteristic CSI feedback reporting be selected on the basis of an channel information is, using scheduling UE a particular time/frequency resource for a channel condition and maximum is similarly.

Furthermore, such a particular pointing information NW-CSI-IM eNB set (for example, cluster CoMP) belonging to Multicast/broadcast to eNB defined to be transmitted can be or set of functions. Wherein, said specific eNB set on the middle of the predefined and it is possible, , or a separate Xn-signaling eNB are specific in advance (or eNB set) determined through negotiation of between may be or set of functions. I.e., a pointing information said NW-CSI-IM eNB one recipient that are transferred to the unicast signaling as well as, to a plurality of belonging to cluster CoMP eNB signal Multicast/broadcast toward the table 8 such as by transferring information element, a plurality of which receives it and the corresponding sender eNB eNB indicated by the of a frequency/time resource map consults a maximum in the form best-effort (best effort) map resource/time a large index NW-CSI-IM a relative to one another (are) indicating order of time series, (or to the uppermost) can be to exchange Xn-signaling. The, for example, frequency selectivity not show differences a large (frequency selectivity) PRB relative to, said NW-CSI-IM indicative information is received the eNB the right receiver, a sender provides first said Xn-signaling eNB consults a resource map/time frequency of as possible the same NW-CSI-IM index (are) selects, with another eNB recipient (are) toward the eNB Xn-signaling to transmit a preferably. For example, said table 6 subscribers 7 of in an example, is first eNB2 a particular frequency/time resource map for the future notification indicating "NW-CSI-IM index 3, 4, 7", the corresponding maximum the eNB3 frequency/time resource map while along a similarly shaped (for example, some frequency/time resources are overlapping each other may be different may be filled in the space but mxm frequency/time resource are so stitched as to overlap with resource map sets a frequency/time) herein Xn-signaling to eNB1 by directing "NW-CSI-IM index 2, 4, 6" can be. ENB2 and eNB3 NW-CSI-IM indicative information is received from eNB1 NW-CSI-IM index 4 takes an intersection herein containing the same motion compensated frame interpolation, select a a particular CSI process is for the subject to be preferentially schedules UE can be considered.

Furthermore, said frequency/time resource map pre-provided, such as by separate Xn-signaling CoMP CoMP and area is by irrevocable letter of area is performed by dividing the channels divided by negotiation between eNB, eNB CoMP maximum displayable area is a match between the lower substrate to accomplish a substrate assembly method the (align) can be effected. I.e., each eNB GBR (Guaranteed Bit Rate) bearer, and the like in an CoMP a particular frequency/not applying a pre-for time resources exist can be within a cell are decided, this information among the previously changed and is said CoMP is area where prior negotiation can be for utilizing. More particularly, said NW-CSI-IM index corresponding according a output resources CSI-IM eNB set detail of a pre-configured/may be established (for example, which a geographic adjacent eNB beforehand to subsets such as configuration/setting), among eNB such resource map for said frequency/time match (alignment) is mainly effected with the. can be treated with water. For example, this frequency/time resource map negotiation for a particular cluster CoMP for Xn-signaling eNB even Multicast/broadcast toward the set, and one of the higher in any eNB negotiation with a priority purpose: a method for specifying whether to be may be loaded with.

Such operations are performed to ensure that, in a set of induced by such a specific cluster said CoMP eNB in the aforementioned Xn-signaling. must not be allowed to overlapping. For this purpose, pre-defined or set of functions according to offset and/or periodic, in said specific eNB eNB subsequently will alternate (or to the uppermost) for transmitting said Xn-signaling can be adopting.

Pointing information NW-CSI-IM when indicating a request resource adjustment is

A pointing information NW-CSI-IM, listed in pointing information NW-CSI-IM NW-CSI-IM RE position index (are) set from a received broadcast signal (time/frequency resource position) callee in eNB transmitted by a (interference) signal characteristics for (for example, transmission power and/or precoding information) is, directed actually PRB and/or sub-frame index position signals transmitted by a corresponding recipient eNB (for example, such as PDSCH) characteristics for to each other to conform to the request a can be interpreted to.

NW-CSI-IM pointing information is in the case where the indicating request resource adjustment, a notifying/resource adjustment is pointing information said NW-CSI-IM result indicative of when compared with the case, a detecting signal is interchanged with an eNB recipient and a eNB sender are in the form of aqueous. Furthermore, a notifying/resource adjustment is pointing information said NW-CSI-IM indicating result a proposed to the are exemplary of the present invention, sender eNB and a recipient eNB change to each other, is pointing information NW-CSI-IM indicating in the event of a request resource adjustment can be applied as exemplary.

Additionally, indicating a request resource adjustment NW-CSI-IM eNB the right receiver receiving indicative information is the request (accept) or denial to the method for dyeing indicating (reject) can be response to the signaling.

Such response message is simply accepted but indicate or denial to the, other the meaning of or denial to the accommodated in a manner that enables it may be delivery.

For example, for the "rejection" Xn-signaling, indicative of a result a notifying/resource adjustment said pointing information it possible to replace NW-CSI-IM. Recipient receiving a request to resource adjustment this case the eNB, coupled to the recipient and randomly choosing "rejection" of other types eNB a notifying/result the resource adjustment reorganize the, and send requested resource adjustment the Xn-signaling to a sender eNB can be understood.

Furthermore, for "receiving" the Xn-signaling, recipient eNB eNB sender is to send response signaling to the event that the receiver does not (i.e., when the invention eliminates the need for response) can be to set the mobile including a. I.e., sender indicating a request resource adjustment is eNB NW-CSI-IM indicative information is when Xn-signaling to eNB recipient, recipient eNB separate there is no response from a default, defined which is received said request can be or set of functions. In speed and position centric the operation can be effectively utilizing. For example, CCN (or CCN a lower cavity and a specific eNB (for example, Macro-eNB), the them in constitution: a method is CCN hereinafter) to the other (are) eNB indicating a request resource adjustment when Xn-signaling NW-CSI-IM indicative information is, a recipient which receives it and eNB is signaling response message recipient or the vacuum pump to finally eNB eNB sender is of the type of (for example, only when Macro-eNB or CCN is eNB sender) quality degrade caused by the power consumption vertically for signaling response message indicating that may be loaded with. In this case, the resource adjustment eNB Xn-signaling transmitted by a sender in the form of request but, they won which acts as an instruction resource adjustment, eventually eNB sender (for example, CCN) eNB are recipient and the other (for example, non-CCN) including a speed and position centric. can be configured with a.

While, in distributed structure, indicating a request resource adjustment NW-CSI-IM eNB interface for indicative information is received for are when a message response for, indicating a request resource adjustment NW-CSI-IM eNB sender transmitting the indicative information is the, NW-CSI-IM pointing information indicated in a particular frequency/time resources when schedule UE, said a particular frequency/time resource processes with respect to linked with specific NW-CSI-IM index is based on information feedback CSI UE, downlink transmission be applied to a precoder and, such as MCS of determining or may be selected.

Centric Xn-signaling scheme speed and position

In the present invention in in several exemplary examples to propose, in particular centric speed and position is used advantageously in a Xn-signaling as extracts additional features which may be, (benefit metric) metric benefits respect to the described hereinafter. Benefit metric, each eNB are CCN a particular frequency/time resource map to its UE him metric is (utility) or usefulness scheduling metric may be described. Hereinafter (utility metric) usefulness metric in terms that but by using the mixture, the UE scheduling metric (benefit metric) metric or benefits (UE scheduling metric) that are representative should understood as terms.

Rotation Utility metric a particular frequency/time resource (for example, PRB and/or sub-frame index unit defined as resource) when specific UE schedule data rate can be expected a value for (throughput) or the throughput rate (data rate) can be defined. Specific by way of example, a particular utility metric UE of the available data rate to the expected (or the throughput rate) of corresponding parameters UE average data rate of a value obtained by dividing an (or average throughput) can be defined. Herewith is the collector, and/or, a particular utility metric UE of the available data rate to the expected (or the throughput rate) of corresponding parameters of QoS reflect UE derived value (for example, corresponding UE of QoS according to pre-defined or the by the function the calculated value) can be defined.

For example, utility metric value for a larger corresponding frequency/time resources eNB corresponding is scheduling UE in c language can be that means, glass. For utility metric particulars, such as in the case of a sender for Xn-signaling eNB CCN or the like, having high utility metric said sender eNB is muted frequency/time resource in data rather than a carrying out (for example, PDSCH) would prefer transmission provided to a CCN information that can be the layout based upon the resistance value.

Furthermore, a particular frequency/time in an ms culture fluid having a plurality of utility metrics is Xn-signaling may be. In this case, each different utility metric (hypothesis) hypothesis CoMP assume the calculated perspectives and a can be value. Wherein, different interference environments different email widow, a web page or hypothesis-CoMP which means that it is possible, and, said table 7 subscribers 6 eNB plurality of such as duplication management apparatus showing whether each muting may alternatively be defined as a pattern, different CSI process unit may be loaded with mixture by the addition of an initiator.

Sender different home is eNB Xn-signaling hypothesis CoMP method as representing a, said table 7 subscribers 6 one or more such as exemplary CSI-IM form of setting information (or IMR) can be used. For example, "NW-CSI-process index (are)" Xn-signaling according path for a vehicle or utility metric value, or "NW-NZP-CSI-RS index (are) and/or NW-CSI-IM index (are)" utility metric according Xn-signaling calculates a value. manner in which the.

For example, below of tables, via a particular frequency/time resource unit 9 such as a (for example, PRB units and/or sub-frame index unit) specific to that particular NW-CSI-process index (are) UE corresponding according to reflect data distributed result feedback CSI of data (for example, PDSCH) assuming that the transmission, the utility metric path for a vehicle can be Xn-signaling value thereof.

Said table 9 as described, the utility metric may have step of U, NW-CSI-process and utility metric index (are) with a corotating twin composed can be Xn-signaling in the form of (pair).

Furthermore, different NW-CSI-process is calculated based upon the hypothesis is another utility metric can be Xn-signaling. I.e., said table 9 as described {utility metric, NW-CSI-process index (are)} plurality pairs or one of a pair of can be Xn-signaling.

One NW-CSI-process NW-NZP-CSI-RS one index combination of index NW-CSI-IM one index being constituted considering the, index NW-CSI-process establishing an optical fiber at a side (are) according the use the compute the utility metric, directed by the unification index NW-CSI-process NW-NZP-CSI-RS channel based on the measurement is carried out with the (or desired signal), directed by the unification index NW-CSI-process NW-CSI-IM for measuring the interference for based on the, such measurements a/creation calculated based results CSI feedback information (for example, RI, PMI, CQI) based on PDSCH is transmitted when assumed to calculates utility metric the widest sense of that. may be interpreted.

Such utility metric for a plurality of including Xn-signaling eNB CCN it receives from the, received information the considered ISDN, eNB plurality of said specific are involved or eNB set (for example, cluster CoMP) optimization of overall in can be a (global optimization). The, arbitration of resources at each eNB including Xn-signaling information indicative of request for eNB by is then sent to the (for example, the aforementioned in an example invention as described above wherein, resource arbitration request indicating a NW-CSI-IM pointing information (substantially resource adjustment command) the Xn-signaling a), the non-operation NIB CoMP can be.

For example, in an ms culture fluid having a time a particular frequency/is CCN utility metric most value thereof is higher resource adjustment is provided to rapidly and as a result, the selected CCN calculation of utility metric NW-CSI-process index (are) forming a base of a header includes the first CID what (i.e., said table 9 such as a {utility metric, NW-CSI-process index (are)} pair of header includes the first CID), corresponding NW-CSI-process index (are) associated with the specific NW-CSI-IM index (are) can be viewed. The, the resource arbitration request CCN (or resource adjustment command) pointing information NW-CSI-IM indicating that the eNB Xn-signaling in the form of can be sent to.

Establishing an optical fiber at a side, said table 9 "NW-CSI-process index (are)" in an example of the "NW-NZP-CSI-RS index (are) and/or NW-CSI-IM index (are)" it possible to replace. In this case which of tables, via utility metric IE, such as 10 can be is defined.

9 table said defined such as a utility metric IE embodiment relate to using Xn-signaling, a description in said table 8 "NW-CSI-process index (are)" a "NW-NZP-CSI-RS index (are) and/or NW-CSI-IM index (are)" a can be applied as in the embodiment.

Specifically, each eNB the, NW-NZP-CSI-RS directed channel based on the measurement is carried out with the (or desired signal), directed based on the for measuring the interference for NW-CSI-IM, such measurements a/creation calculated based results CSI feedback information (for example, RI, PMI, CQI) based on PDSCH is transmitted when assumed to calculates utility metric the widest sense of that. may be interpreted.

Furthermore, said table 9 such as in an example, NZP-CSI-RS index (are) is information indicating a, { utility metric (U bits), NW-CSI-IM index (are)} one or more pair of encoded from all Xn-signaling may be is constructed. In this case, forming a base of a corresponding utility metric calculated NW-NZP-CSI-RS index (are) the, a sender for transmitting utility metric notifies a pointer are separately eNB may be interpreted to, sender eNB a particular transmitting and setting/is (are) is index NW-NZP-CSI-RS tacit directed may be interpreted to.

Utility metric Xn-signaling scheme of similar information

Described in the aforementioned exemplary utility metric (or UE scheduling metric, or benefit metric) Xn-signaling operation for, other similar information (for example, map or priority (priority map) (preference rating) grade preferences) of at least substantially co-extensive operation Xn-signaling can be applied. In hereinafter, utility metric, preference rating priority map and. specifically, respect to.

The Utility metric, establishing an optical fiber at a side, a particular frequency/time resource (for example, PRB units and/or sub-frame index unit) specific UE when schedule data rate can be expected a value representing that the pixel or the throughput rate is defined. Furthermore, the calculated utility metric are is experienced by discrete sine transformation pre-defined value (quantization), selects the receiver based on a mapped may be and the semantic description. However each seller network (network vender) eNB implemented scheduling since the does not were identical, each eNB utility metric computation scheme are unequal. may be more likely to have. If network operator networks with different transmission conditions implemented by seller single eNB CoMP cluster comprising the, each eNB Xn-signaling are then calculated by a utility metric values are different the represented by the criteria may value, for the receiving may be loaded with. Therefore, utility metric and similar, but simpler realizations of comparative reference using may be loaded with.

The (priority map) map or priority (preference rating) grade preferences, set to level simplified unlike utility metric (for example, 4 step levels defined directed to one) can be. The priority map or Preference rating taught 10 subscribers 9 table said utility metric much like an index and NW CSI may be pairing. Specifically, in Xn-signaling, { preference rating (or priority map), NW-CSI-process index (are)} one or more pairs of, { preference rating (or priority map), NW-CSI-IM index (are)} one or more pairs of, or {preference rating (or priority map), NW-NZP-CSI-RS index (are) and/or NW-CSI-IM index (are)} one or more pairs of the list may be.

Such preference rating (or priority map) the, which can differ from the according to implementing eNB dependent on scheduler algorithm has no need of a metric, simplified preference or priority of display of the squeegees are configured to move. may be utilized. Such preference or priority value in extracted, direct provider network not by a seller network software based algorithm by insert, embodied by seller different networks eNB the second said to a value which is comparable any or priority preferences CoMP can be utilized in cluster.

The aforementioned utility metric, UE scheduling metric, benefit metric, preference rating, signaling of such as priority map, NW-CSI-process index (or NW-CSI-IM index) a particular indicated by the hypothesis CoMP (i.e., CoMP in each eNB operation of (for example, muting whether, such as home transmission (transmission assumptions))) with assumed eNB sender in preferred benefit // using of its own, and when other degree is indicating to the eNB, the specific CoMP hypothesis-when subjected to said sender eNB at a distance when viewed in the latitude and the longitude of the place eNB substance providing other characteristics desirable in the operation of what can be interpreted to inform.

Utility metric in the present invention to propose, UE scheduling metric, benefit metric, preference rating, signaling of such as priority map, in the prior art of signalling eNB principle basic ring (i.e., sender eNB his/her operation other eNB to inform a on the moving other eNB not involved the operation of) beyond a, sender eNB CoMP as well as his/her operation eNB operation of the other devices in the cluster (i.e., network performance optimization of represents a sender eNB amount is decided to other eNB of a preferred operation and/or sender eNB the desired operation of other eNB) what in herba is provided to obtain a tobacco signaling indicating a, signaling from inter-of the existing method eNB Saga-has difference.

Xn-signaling scheme Utility metric related information of

Said table Xn-signaling for utility metric such as 9 subscribers 10 in addition to or in place of the, such utility metric element can compute the time frequency/information through Xn-signalin resource unit can be exchanged between eNB. Furthermore, in speed and position centric, utility metric element can compute the non-CCN information transmission to CCN are eNB may be designed.

Next information element said least one of exemplary may include a.

-Be scheduled reporting CSI UE (are) of (for example, RI, PMI, CQI) one or more sets of

-Be scheduled for measurement report UE (are) of (for example, RSRP) one or more sets of

-Be scheduled (are) of UE SRS (Sounding Reference Signal) received power

-Be scheduled (are) the user detecting unit throughput UE use of (User perceived throughput; UPT)

-Be scheduled (Proportional Fair metric) metric PF UE (are) of

-Be scheduled (are) UE QCI (QoS Class Identifier) of

In exemplary said "UE be scheduled (are)" the, time frequency/is read from stored information eNB participating in the scheduling source UE (are) includes the information for the element information defined to be interpreted to into the sense that can be or set of functions. I.e., sender eNB is furnished with a each individual UE said for that delivered to a recipient information element which is not the eNB, optimal (best) UE or representative said element for (representative) UE that information can be understood. The, is mounted to the peripheral area and overhead Xn-signaling, entire UE are some, but not information where the time when the (are) determines UE CCN was collected corresponding CoMP cluster propagation optimization of't problem to perform a.

More particularly, said exemplary "UE be scheduled (are)" in the "(activated) set of UE" can be interpreted to into. The activated elements for all state (active) UE to preart signaling information is also matched with the first, of the state or activated at UE UE part of (part UE has a sender eNB can be is selected) determines also to preart signaling information is. may be interpreted.

Some even signaling information is determines UE, "set of UE" of the, resulting in a lower limit of number UE can be set to 1. I.e., sender at least one necessarily the eNB UE determines the operative to signal information can be defined, and a.. For example, local Xn-signaling, on an element such as a to send the information requested or when directed by (for example, other network nodes from a predetermined operation message (invoke message) by may be/instructing request), or sender eNB was originally said inter-eNB information element transmitted by screw-combining a pressed bolt Xn-signaling, "set of UE" of the, resulting in a lower limit of number UE can be set to 1.

Or, "set of UE" of local Xn-signaling UE number, resulting in a lower limit of the, type of information element 0 setting the according may permit. For example, said "be scheduled UE (are) of CSI reporting (for example, RI, PMI, CQI) one or more sets of" of (are) UE be scheduled (i.e., "set of UE") belonging to a minimum number UE is defined is 1, "be scheduled UE (are) of measurement reporting (for example, RSRP) one or more sets of" of (are) UE be scheduled (i.e., "set of UE") belonging to a minimum number UE may be defined is 0. The, element information CSI Xn-signaling UE in defining at least one of the information relates to other eNB provided to but, RSRP selectively providing information can be can be interpreted to. Or, RSRP does not present information (i.e., 0 of UE for partially-sintered layer that provides a RSRP) when the, is provided prior to (are) for specific been UE RSRP information is not varied the amplifier causes the amplitude distortion that means no to update the value may be loaded with.

Furthermore, "UE be scheduled (are)" or "set of UE" UE belonging to the, minimal requirements UE satisfying (are) may be selected from. For example, capable of setting CoMP UE (for example, transfer mode UE set for at least and 10), one or more 2 UE CSI process is, UE capabilities information that can support maximum on the number of process CSI UE is 2 or more, "set of UE" can be defined to be included.

Exemplary information element related to said utility metric additionally to, transfer buffer information (for example, state of transmit queue ("Status of transmission queues")) is can be Xn-signaling.

Status of transmission queues information, packet transfer delay to minimize can be used. For example, length of queue (queue) increases, higher utility metric can be to value is set with a value. For example, transmission of eNB by Xn-signaling information length of (Transmission queue) queue, the queue length is to a user requests a server CCN increases value of utility metric can be changed to give high. (same, maximum delay according to the algorithm a is presented as may be loaded with).

Furthermore, T ms intervals is eNB sender Status of transmission queues information is transmitted to the receiver Xn-signaling. In this case, at any particular time following the next Status of transmission queues at least one information may include a.

One or more of said information, this information Xn-signaling a network node (for example, CCN) the, corresponding information eNB a sender for sending a reradiation to input numerical information in the amount of data that is, upon/reassigning a resource adjustment a reradiation is large amount of data and a farther module and to weight a eNB content-material can render the.

On the other hand, "integrated Xn-signaling" refers to one, benefit metric ("benefit metric") grade or preferences ("preference rating value"), referred to as a Xn-signaling information transfer buffer and queue state information ("Transmit buffer and queue status information") .may be included. The aforementioned "Status of transmission queues" an exemplary information are defined to be transported in form of "Transmit buffer and queue status information" can be or set of functions. For example, "Transmit buffer and queue status information" ("transmit buffer status") buffer status transmitted in said information "specific UE according current transfer buffer state" and mixture by the addition of an initiator, a queue state ("queue status") said information "current by the time of the MAC-transmission queue a reradiation is in a queue state" can be mixture by the addition of an initiator. As such, said "Status of transmission queues" of subdomes plurality the combination of some or of exemplary, various buffer status contents of message that information and convey that information up associated Xn-signaling as can be.

CoMP hypothesis

Frequency domain time/hypothesis CoMP for at least receiving node includes resource allocation hypothetical, the centric adjusting (centralized coordination) .for supporting. Such hypothesis CoMP CCN signaling is determined by the resource adjustment result directed to and may be used, or (time/frequency setting unit without) the signaling for metric benefits which is assumed as a condition hypothetical may be used.

Received CoMP hypothesis received is some doubt whether response to what signaling eNB but on implementation of, eNB received are ignored/receptor for feedback which means that each (for example, YES/NO) may be sent to node for transmitting.

CoMP necessary hypothesis having a time/frequency-domain setting units and for signaling period, and from a and subframes PRB, sub-frames includes a L-bit size dictated by bitmap of sub-frames can be to. Furthermore, different NIB on the consideration of the period and signaling delay, a maximum L problem it is proposed to given 10. CoMP hypothesis appropriate for the signaling periods of L value since the sender node may be different from the user according to, L to signaling information hypothesis CoMP which incorporates or, , allowing the receiving node period value (i.e., L value) can be to. CoMP hypothesis information, cell by power allocation information (muting duplication management apparatus showing whether information, generating portion or power level) may comprise, the cell can be identified by ID.

The benefits of metric associated with hypothesis CoMP

Benefits (benefit metric) metric can be defined as follows.

Benefits associated with hypothesis CoMP metric which, assuming that the hypothesis CoMP associated with sender node of cells when the scheduling in a quantifying benefit that it expects a is information (quantifying).

Cell-specific benefit metric, corresponding in its cell and all active UE relative to, each UE elements given provider from information from the results of a function to define a is calculated as the maximum value. Said element information, associated with terminals and corresponding to a hypothesis to CoMP a CSI reporting (RI, PMI, CQI) set, one or more for measurement report (RSRP), average user throughput with, transfer buffer and queue state information (Transmit buffer and queue status information), QCI. combination of the conductor.

The map also Figure 13 shows a frequency/time resource CoMP benefit be signalled with hypothesis to explain the metric is surface.

In Figure 13 CoMP eNB individual hypothesis for power allocation to can be dictated by list. Power allocation list eNB1 for power allocation value, for power allocation value eNB2, ... , For power allocation eNBN explicitly indicated value can be constructed of the squeegees are configured to move. Or, NW CSI-IM CoMP hypothesis index and a simply configured than such as may be pointed out in. I.e., the individual index value of one eNB can be and directs the operation of.

Benefit metric, time/frequency setting unit without (granularity), associated with may be signaling with hypothesis CoMP. Specifically, an associated metric be signalled benefits CoMP assuming that the hypothesis (for example, the TPS bits that the wireless terminal assumes that the pattern muting/non-muting) sender node of cells in the scheduling that it expects a. value the revenue quantified.

A plurality of node sender may signaling metric benefits, each associated with different metric benefits constitution: CoMP hypothesis. The, benefit metric, CoMP hypothesis (sender eNB key region as well as activation of other eNB information indicative of operation of) a sender for every in terms eNB. to allow for the possibility of preferences.

Benefits be signalled with hypothesis CoMP metric is considering the point, the aforementioned the transition period of metric benefits CoMP transmission period hypothesis (for example, period value L) and a can be set equal to the.

Information of metric benefits B to 0 between integer value (0 to coat the B) can be defined. In its cell and metric is benefits which take account of all active UE the quantified value at a considering the point, for example, .may be set on a port-B=100. A simple by way of example, associated with at least one terminals and corresponding to a hypothesis to CoMP CSI reporting set and average user throughput with waveform signal derived from the metric PF benefits can be metric is calculated. Wherein, for calculation of a CQI onto the one or more for measurement report is (RSRP) can be used in addition. Such calculation is performed in a sender is not CCN eNB, or transfer buffer and queue state information QCI such additional information may be is used. Different node plurality same to the sender of the revenue associated hypothesis CoMP CCN metrics to be connected to either a storage, information provided from member (member) eNB CCN of using all the resource adjustment may decisions on. While, CCN eNB member determination is resource adjustment of when the is offered to does not need to be signaling metric is benefits may. I.e., member CCN eNB desired by the benefits of determining resource adjustment by considering metric bus line structure suitable to high speed so that gas, is useful as the CCN to eNB member is a need to provide metric is profit or loss is since not. If member eNB is CCN contents transmission eNB member is CCN signaling refers to signaling contents transmission "integrated signaling format" is shifted from a predetermined mode to defined, the metric information benefits CCN signaling eNB member is notification of determined resource adjustment contents transmission for the special type/instructions is set to a value which is or, or dropped or (omitted), the reserved or may (reserved).

Such signaling of metric and profit hypothesis CoMP speed and position centric even speed and position distributed as well as can be applied. For example, in distributed structure for allowing a sender when eNB2 recipient is and eNB1, indicated signaling metric benefits eNB1 hypothesis CoMP detects and takes into consideration a terms of request resource adjustment when signaling (or resource adjustment recommendation (recommendation)) .can be understood. In this case, received from the eNB2 eNB1 next, information can be taken into account in determining scheduling of. Specifically, in accordance with the latitude and the of eNB2 eNB1 sender eNB1 future information for operation of an will of a (guarantee) thereby guaranteeing delay performance can be taken into account to, has an associated UE eNB2 a recipient according to is of the form of a single chip CSI feedback reporting. ENB2 for operation of an information recipient, eNB2 best-effort is taken into account in when operating manner (best effort) may be loaded with. Distributed speed and position the signaling can be very much exchange, information about the operation of other eNB of its own, and when eNB2 recipient also can be taken into account in scheduling. For example, various CoMP hypotheses in the most commonly preferred (i.e., greater number of eNB another CoMP hypothesis the gap is formed between the substrate high benefits the metric values) CoMP hypothesis, scheduling final of eNB2 recipient may be used as a home crystal.

CSI and RSRP information

And/or one or more sets of information CSI UE RSRP for a set of information, speed and position distributed and speed and position centric CoMP in both can be Xn-signaling operations for. The aforementioned cell-specific benefit metric, UE CSI being reported together with identification information (ID) and a hypothesized NW-CSI-process identification information (ID) such as explicit UE-include specific information from a, the benefits of information of this type based on metric information signaling CoMP as additional information can be used for. For example, sender eNB UE be scheduled in a PMI for eNB information including CSI when the to, distributed structure for controlling the CSI eNB recipient even based on information including CoMP a CB (Coordinated Beamforming) .may consider operation.

Such signaling of-specific information UE eNB Xn-signaling between caused overload more than for the, QCI, buffer status, average user throughput with Xn-signaling simultaneously information of the elements of the wafer is not processor, such auxiliary signaling-specific UE (supplementary) or selective can be is treated as a information (optional).

Improved RNTP

Improved RNTP signaling of resource map/time at a designated frequency power level and/or of eNB sender on beamforming information related to a notification of an its operation since is recognized as, speed and position distributed in NIB CoMP to be able to support a. The differences ring so that signaling of existing RNTP/ABS (Almost Blank Subframe), the source setting unit (granularity) is frequency-time resource map that extends the domain dimensional 2, multi-level power allocation information is are directed, pointing information in spatial domain (for example, precoding information) .that.

Improved RNTP the, transmission signal power and frequency/time domain 2-dimensional bitmap may include hereinafter. 2-dimensional bitmap each bit of power level of corresponding threshold indicating or otherwise ensure can be. Resource establishment unit, is a unit RB on the frequency, unit sub frames over time can be defined by the map resource dimensional. 2-, K and RB of 2008 for a frame sub-L, K-bit de-bit map and L-bit of bitmap can be designed. In this case, a indicated in of bitmap-bit L (for example, 1 bit corresponding to a junction between the) sub-frame only the valid of bitmap-bit K interpreted to can be. Multiple-level signal power rather than using a to, the use of only one signal power may be loaded with being sufficient.

Integrated Xn-signaling

The aforementioned "NW-CSI-IM pointing information is resource adjustment when a notifying/result indicative of a" and "NW-CSI-IM pointing information is indicative of a request resource adjustment when" a description dually function as a pipeline and a interference adjustment for recommending/request/a notifying // clear results for such as command Xn-signaling one integrated signaling indicating that can be designed as format. In hereinafter, through such signaling format adjusting CoMP CSI-IM map (CoMP Coordination CSI-IM map), i.e., . referred called map CCC. Table 11 the CCC map exhibits and one example.

Table 11 such as in the case of integrated CCC map, CoMP eNB same to the sender of within the cluster, recipient eNB (are) and other eNB of operations has characterised in that exhibits both a mobile station carries out a high. I.e., a particular frequency/in CCC map NW-CSI-IM listed according resource time index (are) each information eNB of transmission for the home (transmission power (includes [...] ) and/or precoding information) can be viewed. One from the sender eNB transmitted is identified for an assumption, said an assumption associated transmission has made its own eNB sender at a designated frequency/time resource remains the same on the widest sense of notification advertisement exposure section of T1 to t2.. may be interpreted. Herewith is the collector, and/or, transmitted is identified for an assumption eNB recipient, recipient eNB said an assumption associated transmission is at a designated frequency/time resource remains the same on the is eNB a sender will (strongly) recommending the widest sense of that. may be interpreted. Herewith is the collector, and/or, a other eNB (i.e., remaining in CoMP eNB) transmitted is identified for an assumption, corresponding eNB said an assumption associated transmission is at a designated frequency/time resource remains the same on the sender period (strongly) recommending eNB is the widest sense of that. may be interpreted.

Therefore, recipient eNB eNB of the other, the hand of the CCC map with high probability the operation is performed according to and capable of assuming to be, corresponding NW-CSI-IM index (are) for reporting feedback CSI UE having performed in schedule, corresponding CSI final considering feedback information can be to decide on schedule.

In speed and position centric, such as said table 11 specific signaling eNB CCC map (for example, Marco-eNB or CCN) defined to transmit only can be or set of functions. In this case, recipient of a plaque has eNB eNB other as CCC map of operation is carried out according to the wireless terminal assumes that the to be, corresponding NW-CSI-IM index (are) for reporting feedback CSI UE having performed in schedule, corresponding CSI final considering feedback information can be to decide on schedule.

If a particular frequency/time associated with a resource is several indexes NW-CSI-IM are directed, recipient eNB (or other eNB), a hypothesis is transmitted is identified for an said a plurality of indicated when the different between indexes NW-CSI-IM, said recipient (or other eNB) eNB the operation of the "don ' t care" defines or to interpret the to to be set up. Or, at least three NW-CSI-IM indexes when the indicated, is relatively more large number of identical transmission home the DVD camcoder is instructed NW-CSI-IM eNB message is transmitted based on indices (or other eNB) defines or of action with the content is to. may be set.

CCC map of example 11 such as said table, said table 9 subscribers 10 usefulness metric such as (or preferences grade, priority map, or benefits metric) Xn-signaling integrated including information may be loaded with format is provided for. Is exemplary area as and a 12 of tables, via which, aforementioned a usefulness metric, preferences grade, hereinafter term herba is provided to obtain a map or priority benefit in exemplary using term is (benefit metric) metric. them.

Table 12 table respect to applying a description is 11 can be, in addition to the is, directed according NW-CSI-IM index (are) "benefit metric" information can be provided along.

In distributed structure, table 12 eNB transmission signaling integration of retrievals of is for recommending/desired CoMP eNB operation of each in (i.e., CoMP hypothesis) while for informing, corresponding CoMP hypothesis-transmission eNB such an extent that in the latitude and the longitude of the notifying additional whether slave channel control unit can be interpreted to.

In speed and position centric, integration of 12 table Macro-eNB or CCN is eNB transmission signaling when the, corresponding CoMP eNB are held each in operations (i.e., CoMP hypothesis) order/notification can be interpreted to, the corresponding, a base station, and each same eNB NW-CSI-IM index (are) for application in the transmission an assumption at a designated frequency applied equally on resources/time not to be opened to the.. In this case, an integrated signaling format CCN transmit "benefit metric" having the meaning of original information, integrated signaling format to or reserved (or are not included or), or period of time and thus utilized as bit selector to propose in the present invention can be (for example, benefit metric information value of a predetermined special value when, integrated signaling resource adjustment command/notification serving as the, other value when the member network node (are) is CCN indicating to the signaling being a ring, identification basic may be used). Is not limited in the range of the present invention, integrated signaling format non-metric information participants said information is a glass or other silica containing surface functions as bit selector includes are an exemplary.

Integration of said table 11 subscribers 12 signaling (or CCC map) and similar, but, these with flip-flop of semiconductor memory can be used as an integrated signaling, such as 13 of tables, via below improved RNTP/improved ABS types of signaling may be defined.

Table 13 14 having a integration of exemplary signaling by referring to a described.

Figure 14 shows a frequency/time also improved properties of the signaling respect to resource RNTP map (or improved ABS map) is surface to explain the.

For example, sender eNB is eNB1 and, eNB is eNB2 in assumed to the recipient. Power allocation its own eNB1 value of Figure 14 M1 M1 value is beyond the first and second is interpreted as half, and a semantic notification. M2 M2 is power allocation of eNB2 value without exceeding value is eNB1 to is interpreted as half, and a semantic to recommend to the eNB2. M3, M4, ... The value of, other eNB are power allocation of (eNB3, eNB4, ...) (M3, M4, ...) are each corresponding value over the first and second the other eNB1 eNB is interpreted to recommending to, one of the facsimiles the latitude and the longitude of the recipient eNB2 eNB are crossed power allocation recommendation value assumed to operate according to a information of a scheduling decisions on may.

Furthermore, of Figure 14 in an example power allocation value M1, M2, M3, M4, ... Candidate value that may be set on a port range or can be or set of functions pre-defined. For example, power allocation value P_max P_min ranges are of possible may be set from limited up to the, each value meaning of a maximum power threshold values (i.e., said range one of value directed to the, the designation, the a value is not exceeded. power allocation). Furthermore, power allocation threshold values is 0 the directed (for example, P_min=0 for pre-are defined as the and, it is instructed P_min), can be means for muting.

14 also improved such as the ABS or improved RNTP, existing RNTP or ABS signaling for, extending ring for signaling for a multi-level features and that, sender eNB its power allocation as well as other information about the for power allocation to eNB for recommending /, which comprises a request characterised in that has.

The aforementioned of the present invention in exemplary, eNB1, eNB2, eNB3, ... ENB with an identifier for the specific, pre-CoMP eNB specific cluster is set defines or in the form set may be proposed. The, of Figure 14 M1, M2, ... Any values are the a value for eNB is predefined, which may be, or each power allocation eNB any value indicating whether the an identifier (for example, corresponding eNB cell ID) (pair) pair and a power assignment values may be signaling in the form of..

Furthermore, the aforementioned of the present invention in exemplary, one integrated signaling in gastric various be applied a in order directed on more specifically, the selection of any that user may further define bit (selector). I.e., value of bit selector according 335, said integrated signaling should be interpreted to into a sense can convey the.

Furthermore, the aforementioned of the present invention in exemplary, such as speed and position centric a particular Xn-signaling eNB in table 13 (for example, Macro-eNB or CCN) transferring a which can be may define.

Furthermore, said example of 12 table 13 table said metric information benefits of the people including together below of tables, via integrated signaling format thus defined and a 14 may be loaded with.

Tables of a plaque has 15 of tables, via below 7 to table 14 exemplary generalized are integrated general exhibits and exemplary signaling format.

Table 15 the resource map in an example of signaling pattern eICIC (Enhanced Inter-Cell Interference Coordination) ABS may be loaded with reuse format (for example, eICIC for designed bit size 40 ABS pattern, such as)

Furthermore, when the application type CoMP "parameter set associated with" the {NW-CSI-IM index (are), NW-CSI-RS index (are), NW-CSI-process index (are), improved RNTP map (are) (or improved ABS map (are)), benefits metric (or usefulness metric, preferences grade, priority map), beam direction/coefficient including precoding information, NIB CoMP operation to a parameter used (for example, CSI reporting, RSRP, SRS power, UPT, PF metric, QCI)} among the four factors set of one or more element can be constructed as to list.

Furthermore, eICIC, eIMTA (Enhanced Interference Mitigation Traffic Adaptation and BS3), and even in the event of a, the application type another payload such as NAICS (Network-Assisted Interference Cancellation and Suppression), parameters associated with the corresponding application (for example, said CoMP, the application type associated parameters, precoding information, multi-level power information, modulation order information) including at least a high element parameter set is setting can be or indication.

For example, when eICIC or CoMP is ", the application type", "related parameter set" the CSI measuring parameters and CSI-IM mapping related information may comprise an.

NAICS is when ", the application type", "related parameter set" encodes the modulated order, CFI, PMI, RI, MCS, resource allocation, DMRS port, n^DMRS_ID, transfer mode (TM), RS such as setting information may include a. Furthermore, in the case of NAICS said associated parameters are, at a designated frequency/time resource map the applied information as can be and interpreted.

Furthermore, predetermined information ", the application type" index (for example, 00,01, ...) and dictated by, index value 335 thus "related parameter set" includes what information to reduced noise indicated is verified by communication with the may be. Or, selective information ", the application type" may be defined (optional), the "related parameter set" is what information must analysis how or whether each of the plurality of sectors is set at default whether may. Or, "related parameter set" tacit according to information forming of particular ", the application type" (index a particular to indicate the type or applications) is instructed defined which may be or set of functions.

In the aforementioned exemplary Xn-signaling formats to propose, a base station and a terminal exchanged between an upper layer signaling (for example, RRC signaling) for format can be pattern is eliminated. For example, folded in such a manner that the terminal upon receiving the RRC signaling, CoMP eNB operation of in (or transmission home) indicates how much of it is present and, CoMP by considering same can be receive operation.

A further exemplary a drain terminal divided-NIB CoMP eNB 2

For requirements CoMP

NIB CoMP operations for, CoMP predetermined within the cluster information about the requirements (for example, reference signal, CSI process and CSI-IM setting the used information on an establishment) should given. Although reference signal setting, pre-determined CSI-IM process and CSI RRC-only UE UE are presented to but eventually the via signaling, setting, or the like, that has CSI-IM and CSI-RS, and MS3 O M (operation and maintenance) predetermined aided signaling backhaul or network-wise (NW) it is preferable that the adjustments. For example, NW CSI-IM CoMP is index set and predefined within the cluster, this resource CSI-IM eNB of each according muting/non-muting or "don ' t care" operation can be directed to. Furthermore, these NW CSI-IM eNB indexes are of the circuit board with the index set is selected by by, associated with the corresponding eNB UE to RRC drain terminal divided by m. not to be opened to the set.

ENB according resource CSI-IM flexibility for operation of an individual order of specific materials selected from coated fabrics, for example, multi-level power allocation and/or CB and the like information setting precoding for CoMP within the cluster signaling other after the. Similar to exemplary CSI-IM, NW RS setting index, NW CSI CoMP index is setting process to be set up within the cluster.

Signaling radio base station resource adjustment

A resource adjustment NIB CoMP necessary for the aim of common information (for example, CoMP within the cluster arbitration of resources at request/recommendation the aim of or, or resource adjustment the aim of notification/result) considering the point having, these information, a simplified signaling (simplify) and preferably integrated (unify).

The recommendation request/resource adjustment, , the factors scheduling CoMP eNB member information is provided to a CCN from, for example, individual UE CSI for reporting (RI, PMI, CQI) one or more sets of, one or more individual UE for measurement report (RSRP), for individual UE SRS received power, UE UPT (User Perceived Throughput) for individual, cell by resource utilization information, QCI, for individual UE PF metric, indication of request resource adjustment (frequency/time/power/spatial domain resource allocation in a on), setting/reference signal CSI-IM setting process/CSI blood storing chamber, and a regulating-balancing of requests indicating lamp may include a.

Notification/result resource adjustment, adjusting result from CCN eNB member is (are) informing the, for example, resource adjustment indication of result (frequency/time/power/spatial domain resource allocation in a on), process/CSI setting/reference signal CSI-IM blood storing chamber, and a regulating setting may include a indicating lamp result.

The first and second two types of signaling in, signaling for recommending request/resource adjustment reflects most light energy which generated from signaling define formats without the need, integrated signaling that defines a format it is preferable that the.

Furthermore, "for individual UE" information, needs to be shared necessarily within the cluster may not. In place of the, sender eNB in terms of a particular frequency/time resource on a map "UE to be scheduled" and it is more include the information may be effective in.. Each eNB in final scheduling determined (i.e., determined for what may perhaps be its last UE be scheduled) individual eNB is hear which is used, a schedulable gave all his UE eNB information to the other for allowed to share for information exchange to the result that no overhead because may generate an over-the-, optimal (or representative) UE (are) for sharing information about. said difference.

Furthermore, speed and position centric CSI according UE even reporting information, RSRP, SRS power, UPT, QCI and a necessarily such that information such as may not. While, frequency/time resource according UE representative optimal be scheduled (are) a preference grade (or usefulness metric (utility metric), or PF metric, or benefits metric) shared between plural memory cell arrays can be said difference. The CoMP for sharing information within the cluster resource eNB the is method for dynamic traffic control in a, final of individual eNB for scheduling decision is since not. Therefore, simplified preferences (or benefits metric values) grade allows for using can be.

A particular frequency/time resource map a simplified preferences rating information (or benefits metric information) the, which is assumed and an indication of hypothesis CoMP it is preferred that a be signalled with. Wherein, CoMP hypothesis CoMP eNB in home for operation of an are (for example, eNB1 the muting and, the muted eNB2 output unit) is, is a predefined NW-CSI-IM index or individual eNB to explicit power allocation list when an is represented by the cell a simple manner by means of.

The map also Figure 15 shows a frequency/time resource CoMP benefit be signalled with hypothesis to explain the metric is surface.

In Figure 15 CoMP eNB individual hypothesis for power allocation to can be dictated by list. Power allocation list eNB1 for power allocation value, for power allocation value eNB2, ... , For power allocation eNBN explicitly indicated value can be constructed of the squeegees are configured to move. Or, NW CSI-IM CoMP hypothesis index and a simply configured than such as may be pointed out in. I.e., the individual index value of one eNB can be and directs the operation of.

Preferences grade value (0 to coat the L) 0 to L between integer value can be defined. For example, .may be set on a port-L=100. Preferences grade value, directed CoMP hypothesis-applied when assumed to expected eNB same to the sender of benefit for considering. can be expressed as a level preference. Or, the benefits of described such as 13 also said metric values is instead grade preferences may be applied to.

Integrated signaling format of Figure 15 for analyzing a exemplary respect to the described hereinafter.

In speed and position centric CCN is eNB eNB member which is not the sender when the, integrated signaling eNB member of Figure 15 in terms of resource arbitration request/recommendation is analysis disclosed. The, member CCN eNB provided from all information adjusted based on the may decisions on. A plurality of signaling eNB each member may present the user with, different signaling each CoMP hypothesis (sender eNB key region as well as activation of other eNB in a hypothesis for operation of an) grade different preferences (or benefits metric values) information being indicative may include.

CCN is eNB sender in speed and position centric when the, integrated signaling of Figure 15, the resource adjustment is determined by CCN result/notification disclosed interpreted, eNB member all a receiver is in accordance with the teachings the corresponding notification. Specifically, in Figure 15 the hypothesized CoMP the eNB each received indicating hypothesis index has NW-CSI-IM CSI-IM resource on operation content (for example, transmission power value, whether muting, such as precoding) equal to, at a designated frequency/time resource for a. operation is. So must, each eNB eNB the other ensure as the DVD camcoder is instructed operation of assumed to be and, based on resource CSI-IM corresponding UE of most recent CSI feedback reporting directly applied, at a designated frequency to update and manufacture a resource/time as they finally result UE scheduling can be determined. Furthermore, according to mode such, each eNB is CSI-IM resource sent to a destination on what kind of signal has been generated can select the freely, the techniques are NIB CoMP types of CB may be utilizing at low rpm and at high rpm.

ENB of individual in Figure 15 (individual eNB of cell ID printing which are identified) explicit power assignment list are used is in the case of format, in the relevant portions of the-resource/time at a designated frequency, the transmit power of the eNB, corresponding threshold values power eNB directed. should not exceed a value. This power different threshold may be set level, when transmitted signaling such from CCN, including operation of a plurality of is eNB improved RNTP/ABS can be layout based upon the resistance value of signaling.

Furthermore, when the same to the sender of format eNB CCN is of Figure 15, preference rating information the omitted (or benefits metric information) (omitted) or clamped (fixed value) values may be set. The, speed and position centric CCN in signaling from interpreted as notification/result resource adjustment. because. I.e., member CCN eNB desired by a preference rating information (or benefits metric information) determined resource adjustment on the consideration of the bus line structure suitable to high speed so that gas, is useful as the CCN to eNB member matching preference rating information (or benefits metric information) since the conveyor need not be in is provided is. The present embodiment as shown in the example is eNB member CCN signaling contents transmission CCN eNB member is integrated signaling contents transmission is shifted from a predetermined mode to defined signaling format, preference rating information (or benefits metric information) receives an CCN signaling eNB member is determined resource adjustment contents transmission notification of an indication that the revision is related type/instructions fixed/or is set to a value which is special, or dropped or (omitted), the reserved or may (reserved).

Integrated signaling in distributed structure of Figure 15, said sender in speed and position centric among exemplary eNB CCN is a description is when the user client receiving the game can be applying most. For example, for allowing a sender when the eNB2 recipient is and eNB1, grade's preferences eNB1 signaling integrated of Figure 15 in terms including eNB1 recommendation request/resource adjustment is the layout based upon the resistance value. Next, information related received eNB2 recipient scheduling of. may consider determination. Specifically, the operation of the sender eNB1

Specifically, in accordance with the latitude and the of eNB2 eNB1 sender eNB1 future information for operation of an will of a (guarantee) thereby guaranteeing delay performance can be taken into account to, has an associated UE eNB2 a recipient according to is of the form of a single chip CSI feedback reporting. ENB2 for operation of an information recipient, eNB2 best-effort is taken into account in when operating manner (best effort) may be loaded with. Distributed speed and position the signaling can be very much exchange, information about the operation of other eNB of its own, and when eNB2 recipient also can be taken into account in scheduling. For example, various CoMP hypotheses in the most commonly preferred (i.e., greater number of eNB another CoMP hypothesis the gap is formed between the substrate preference high a terminals comprise a metal pad and a grade) CoMP hypothesis, scheduling final of eNB2 recipient may be used as a home crystal.

Improved speed and position distributed RNTP-type information (for example, frequency/time/power/spatial domain) and improved ABS information (for example, power/spatial domain) can be signaling is, these information, a frequency/time is obtainable by exposing said point eNB sender on resource power level and/or of beamforming information related to a notification of an its operation is recognized as.

The differences ring so that signaling of existing RNTP/ABS (Almost Blank Subframe), the source setting unit (granularity) is frequency-time resource map that extends the domain dimensional 2, multi-level power allocation information is are directed, pointing information in spatial domain (for example, precoding information) .that.

Speed and position centric format signaling integrated said of Figure 15 (for example, sender eNB is when CCN, when the user client receiving the game CCN) or distributed structure is which may be applied to both, sender eNB serves for instance to contain notification operation of can be, improved RNTP/ABS may include little signaling. Furthermore, other format signaling integrated said of Figure 15 eNB operation of request/recommending can be uses. Therefore, improved RNTP/ABS subset of an integrated type information signaling format signaling information can be the present. I.e., of Figure 15 integrated signaling by preference in grade value eNB/or other information element, and the operation of request/recommending an information element encoded to an optional if design to element (optional), speed and position centric provider network structure is type or dispersion can the flexible signaling that defines a format can be.

However, distributed structure performs signaling applicable only, the first and second improved RNTP/ABS is defined separately signaling type information, in addition, also integrated signaling format such as 15 NIB CoMP structure tuning productions center of supporting defined which may be loaded with.

In this case, at a designated frequency (usage) also on resource/time status report to signaling (i.e., having feedback information from at eNB recipient) may be loaded with is required. For example, sender information are directed to eNB non-CoMP UE how for scheduling CoMP UE and may be capable of reporting feedback whether used.. Such a feedback information, similar to existing ABS status report, each eNB eNB considering feedback information from the other backhaul the controller determines that the user used to determine for signaling messages can be used.

The display unit to highlight a Xn-signaling (granularity) unit

The aforementioned of the present invention in exemplary invention as described above wherein, benefits associated with hypothesis CoMP metric may be-signalling Xn.

Frequency domain time/hypothesis CoMP for at least receiving node includes resource allocation hypothetical.

Received CoMP hypothesis received is some doubt whether response to what signaling eNB but on implementation of, eNB received are ignored/receptor for feedback which means that each (for example, YES/NO) may be sent to node for transmitting.

Time/frequency domain on unit perform setting required hypothesis CoMP (granularity) and rate can be given as follows. For example, T (T=5) ms maximum hypothesis CoMP material may have a signaling period. Furthermore, signaling period and the same frame number by a sub frame defined based on a sub-identified by index in frame units, regulatory domain (for example, cluster CoMP) identified by ID cell in a into cell units, one RB establishment of a unit in the form of bitmap hypothesis-CoMP signaling may be.

Wherein, signaling setting unit for said SSPM 1-way signaling, 2-way described in exemplary signaling for a specific time as a section and/or in particular for can be present to exemplify embodiment.

Furthermore, one RB (subband) one sub-band rather than the display unit to highlight a bitmap hypothesis-CoMP unit may be signaling in the form of.. Setting minimum of feedback CSI of the UE is a unit subband units is formed inside the tie. into account. Furthermore, the display unit to highlight a hypothesis CoMP Xn-signaling as units of subband has a, transmitting node (i.e., sender eNB) his/her system bandwidth (system bandwidth) a rod connecting shaft to a hypothesis CoMP Xn-signaling Xn-signaling or a separate with can be delivered to the..

For example, system bandwidth is defined according the table of which size sub-bands which 16 subscribers can be thus defined and 17.

Table 16 the system bandwidth (RB unit) size of band a defining which is used, in the case of reporting CSI periodic 17 table downlink system bandwidth, bandwidth portion and a sub-band size (unit RB). f O defining the relationship.

Or, system bandwidth is defined according the table of which size sub-bands which may be thus defined and 18.

Table 18 in the case of a non-periodic reporting CSI downlink system bandwidth, bandwidth portion and a sub-band size (unit RB). f O defining the relationship. Table 16 subscribers 17 as compared to exemplary, the respect to bandwidth the same system in a sub-band is and the valve disc is made smaller size, pixels in the estimated more unit setting a sub-band can be understood.

The first and second exemplary sub-band setting such as using units, frequency domain hypothesis CoMP may further define setting unit.

Furthermore, information is CSI Xn-signaling UE for a set may be, said units setting same 16 table, table 17 subscribers 18 defined by the sub band setting unit may be loaded with.

For example, the over a subset of UE CSI Xn-signaling is one or more sets of information can be. Exchange of one or more sets of information said CSI need rate can be given as follows. For example, maximum 5 ms may have a signaling period, additionally, by a request of eNB CSI reporting to a non-periodic manner can be also supported in. Furthermore, signaling period and the same frame number by a sub frame defined based on a sub-identified by index in frame units, identified by ID cell a into cell units, subband sub-bands which shows identified by index (wherein, a sub-band size said table 16, table 17 subscribers 18 conform to negative) unit, identified by unit a UE UE ID, one or more sets of information CSI (maximum 4 one set) and each CSI CSI process associated with the information set (the cell-specific CSI process is identified by ID) to may be signaling assumption.

Wherein, CSI CSI information associated with the home processes the for signaling, each corresponding UE CSI set to information contained in the ID process (for example, one NZP CSI-RS resource, one CSI-IM resources, etc.) a CSI Xn-signaling for a set information with the signaling or a separate. may be buffered. Or, each individual UE CSI process setting information and corresponding CSI eNB to a plurality of ID process for exchanging or in advance between are the key signal (for example, OAM (Operation And Management), such as by "cell-specific CSI process ID" such as a network-wise (NW) to eNB between inherently present in (unique) identifiable CSI process ID is eNB between preset on of the flag is detected), "home processes CSI associated with" the CSI process ID (i.e., NW-CSI-process ID) .said difference program to signal only.

Furthermore, "each CSI information set associated with the home processes CSI" the for signaling, (frequency/time regardless to the grafting unit resource establishment) CoMP home generator to shift the program to signal can be format. I.e., specific CoMP CSI corresponding hypothesis signaling as to the information set, is either permitted to expand. Wherein, frequency/hypothesis CoMP original resource establishment time but what is defined based on units, main compress-encoded signaling set of information to the CSI eNB based is coupled with the power allocation status only (i.e., CSI process included in CSI0 [...] -IM setting, such as, any cells muted whether to perform representation an object only CoMP hypothesis-and those that are necessary does, a certain frequency/time resource on each cell since representing an operation to the service cells need not necessarily be), associated with hypothesis CoMP CSI an compress-encoded signaling set of information to the "frequency/time resource establishment regardless to the grafting unit" as a defined length of. a locking feature may be added.

Furthermore, setting units and rate hypothesis CoMP a further by way of example, the feedback period is set for each individual UE CoMP hypothesis on the consideration of the signaling period (i.e., T ms) .can be set with. For example, said T is supported by the upper case and a predefined value, signaling determines that the sender eNB (CoMP hypothesis and profit metric of separately with or signaling) can be. Sender eNB is including metric and profit hypothesis CoMP whenever to send signaling (or a plurality of signaling at least one bank active signals is) an Internet site obtains a value when the T, T modified whenever recorded value is changed for transportation, the top cover portion T ms CoMP hypothesis and profit metric or the like transmitted signaling including convey that it can be. I.e., is not value falls T T signalled prior to T equal to the recording sheet when the recording sheet is value is presented as can be. For example, a T1 value is signaled is modified at buffered when the signaling value T2, no AC voltage is supplied is another modified T3 until the signaling value, period T2 according to signaling including CoMP hypothesis and profit metric or the like. if the transition is not successful.

Or CoMP hypothesis and profit metric or the like T value including signaling period, recipient eNB designate request/side can signal. A recipient is eNB CoMP hypothesis and profit metric or the like in the latitude and the longitude of the receive signaling including to receive a user authenticating means off the contaminants, sender eNB the T reflect a value can be transmitting signaling. A desired eNB stores a eNB sender or T1 does not have to reflect to surely go value, T1 eNB sender simulation considering the T2 according to a desired period can be to send signaling. If recipient eNB a desired T1 value and other periodic when for transmitting signaling according to T2, T2 information about the signaling period may be the computer system notifies the eNB a recipient.

CoMP hypothesis according to T period, CSI information set and profit metric or the like in a situation where the transmission signaling including, over a subset of UE CSI a information set includes information, signaling transmission a is included in a set of stores said UE UE are. may be different from the user. The, which differ from each other in feedback period according UE can be do. For example, a feedback period of UE1 5ms and UE2 if a feedback period of 10ms, for setting an e-T=5 ms set of information to the CSI is to send signaling including, a time-of-specific transmission CSI information set related to the "set of UE" is included only the UE1, then subsequent 5ms CSI of transmission time point related to information set the "set of UE" may include only UE2.

CB technique

CB also Figure 16 shows a is surface to explain the technique.

The CB CoMP TP any that participate in the different the directions of transmitted by a furnished with a is TP minimizes interference to UE is a technique. For example, in Figure 16 such as a, is directed to TP2 associated with data to UE2 in by transmission or constrained coding to the error correction in range, a serving by TP1 amount of interference to UE1 to minimize capable of avoiding beam selecting or constrained coding to the error correction (for example, selecting PMI2) can be. For this purpose, in the NIB TP1 and TP2 Xn-signaling PMI such as through channel state information is groove is in a long circle shape to transmitting and receiving each other.

1-way Xn-signaling scheme for CB disclosure

A particular Xn-signaling for CB (for example, of Figure 16 TP2) TP one direction (1-way) broadcast for (or one or more other TP to unicast or Multicast) is defined that can be.

At this time Xn-signaling TP for transmitting according to which information is provided, "specific time interval" during "specific band" serving the applicable to PMI is what the can be message indicating a.

A single information contained in the Xn-signaling PMI PMI PMI two or more may be including PMI a may be set. PMI TP other information (are) the, PMI set formed by plate is effected by means of the beam where the a is radiated (are) selecting UE preventive circuit from a potentiometer can be packet. Or, a transmitted by the biosensor transmitter TP2 included in Xn-signaling "PMI set" and a, TP2 is (are) UE to TP1 a PMI2 optimal measurements the this comparison, "PMI set" and a maximum orthogonal PMI2 which report the UE (are) scheduling object by, TP2 for interference from UE minimizing can be schedule. The, beam to avoiding a signal by improving quality generated.

Wherein, "specific time interval" predetermined unit (for example, sub-frame) is represented by or a value which. Furthermore, the "specific time interval" TP to do and CB from fabric based time and initiates a time information indicating whether that's all for when (for example, sub-frame bitmap are configured in the form of the, continuous or discontinuous time information) may be represented by. Furthermore, the first and second sub-frame bitmap form in addition to the what point the (for example, such as particular sub-index) corresponding from disclosure is "specific time interval" is whether may explicitly indicated, said sub-frame bitmap is few-time air after what point the (for example, such as particular sub-index) to the completion of the whether in "specific time interval" may be loaded with explicitly indicated.

Such "specific time interval" to depart for CoMP operation (such as muting/non-muting) sheet when the recording sheet is conveyed (or the start of) frame number (frame number) (for example, a system frame number (SFN)) may be used. For example, SFN Xn-signaling included in a wireless frame are selectively instructed are specified CoMP an operation is to be applied to is able to indicate having. The frame number (for example, SFN) for transmitting the Xn-signaling TP timing of-base can be defined. Or, Xn-signaling TP receiving a Xn-signaling information about the timing of TP for transmitting when the know, Xn-signaling TP said SFN value based on timing of receiving a decides to a value that may be loaded with.

Furthermore, "specific band" unit a predetermined frequency (for example, unit RB) is represented by or a value which.

2-way Xn-signaling scheme for CB disclosure

CB is TP1 TP2 for specifying the Xn-signaling PMI set (information about the one or more PMI) CB using for performing request (request) and, in this regard is to respond to a TP1 TP2 of the type bi-directional (2-way) signaling can be defined. At this time, a reply message transmitted by a TP1 TP2 and other TP (for example, TP3, TP4, ...) Multicast/broadcast ointment, drink or injection may be manner, TP and other TP1 or TP2 is (are) to individually unicast manner may be loaded with.

At this time TP1 transmit the information is included in a message to a request, "specific time interval" during "specific band" specific to that particular PMI set (information about the one or more PMI) CB using a message request for performing can be.

Furthermore, "specific time interval" and the "specific band", the illustrated room for said CB 1-way Xn-signaling uses the option associated with the region is chosen can be.

TP1 in an example said request for sending a message "certain conditions" can be defined, and a..

For example, TP1 and TP2 the notified properties, compares a traffic load of each other (through exchange Xn-signaling to contact with each other), loading situation a predetermined reference above an upper which is, said request for the message transmission condition is met can be would.

Wherein, a predetermined reference value TP2 for loading situation makes a margin to a sink only if said accept defined which can be. Or, TP2 for loading situation when the congested predetermined reference value, even if the delivery request said may be loaded with TP2 of declined.

Furthermore, at such "certain conditions" pre-among TP to be different priorities are established (for example TP1 the master (master) and TP2 is controlled by the slave (slave) may be preset relationship), a priority according to said is TP1 TP2 surface sends a request for the necessarily must conform to the may be defined in such a way that.

Said loading information, one or more CSI-RS setting information, one or more CSI-IM (or IMR) setting information, such as settings information and DMRS or Xn-signaling through the information exchanged in advance such as the stomach TP2 will accept the request (confirm) requirements and the preset values of work information corresponding to when previously provided to TP1, TP2 is TP1 sent to only request muting for a CB (i.e., without response of TP2) CB can be disclosure operation.

The first and second request for the message transmission certain conditions the variables are as defined in and, by corresponding the condition is satisfied from TP1 said request message is to be transmitted would be, such a request receiving a message the has TP2 may be and adapted to receive a second. As such, certain conditions connected necessarily must conform to the request for TP1 TP2 is when (or TP2 is TP1 to respond to and sends a message without when said request along the) of a conditional 1-way Xn-signaling may convey is.

CB in operation Xn-signaling scheme

The aforementioned 1-way or 2-way Xn-signaling specific to transmit the received data, the disclosure is for a predetermined period of time, when CB at specific band, corresponding time interval is automatically in a third step the CB if the flat is set can be defined. Or, corresponding time interval is terminated before additional Xn-signaling (for example, manner 2-way manner or in a 1-way) matched with the extending of a time interval. is satisfied at a. For an interval of time which extending a form of information about the time information may be updated on, plate band information in the form of band information can also be updated on..

Xn-signaling scheme for the feedback symbols for the CB

CB for an interval of time or time interval is set is to, a corresponding scheduled a CoMP UE on the consideration of the CB (for example, considering CB and a determining unit for determining or MCS) PDSCH transmission is performed a feedback information for availability the NC additional Xn-signaling can be defined.

The, adjacent TP CB is (are) are substantially and band time interval having performed CoMP UE corresponding schedules various uses of these materials which designates an ice cutter cuts an availability, unnecessary CB an operation is to be applied to first electrode can be expected.

SSPS CB and a combination of

The aforementioned CB PDSCH essentially operation TP for transmitting a fixed (for example, of Figure 16 TP1) is (are) TP adjacent (for example, TP2) in beam by CB PMI applied with avoiding can be the type which uses a. Herein, the SSPS (Semi-static Point Switching) type are, SSPS is TP for transmitting PDSCH (for example, specific resources in TP1 and TP2 which alternate is for transmitting PDSCH) is changed by (for example, TP2), adjacent TP (are) in (for example, TP1) also extend form a heat insulation is performed by using the CB can be applied. As such, the aforementioned in the description role of TP1 and TP2 can be switching each other.

Also the present invention according to Figure 17 shows a signaling method is flow to explain the.

In Figure 17 number 1 network node and the number 2 CoMP NIB network node in a network or that participate in the is network nodes and which are involved in the. For example, distributed network node number 1 and number 2 CoMP that participate in the speed and position in may be network nodes, each network node number 1 and number 2 in speed and position centric CCN member nodes and. can correspond to.

Step S1710 in number 2 network node number 1 to the network node can be to send signaling type number 1. Number 1 number 1 signaling type of one or more the latitude and the longitude of the network node (i.e., number 1 CoMP hypothesis) CoMP hypothesis can include a, the revenue for hypothesis CoMP each additionally may include a metric. Such number 1 signaling recommendation request/resource arbitration signaling type can be understood as..

In step S1720 from network node number 2 network node number 1 number 2 can be receive signaling type. Number 2 type signaling CoMP hypothesis of one or more entrance network node number 2 (i.e., number 2 CoMP hypothesis) can include a, the revenue for hypothesis CoMP each additionally may include a metric. Distributed speed and position in signaling type number 2 number 2 signaling recommendation request/arbitration of resources at entrance network node may it will be a ring, number 1 the resource adjustment for the network node may it will be a ring signaling notification/result.

Speed and position centric CCN is member nodes signaling type number 1 in a sent to signaling recommendation request/resource adjustment can it will be a ring, number 2 type signaling sent to member nodes is CCN a resource adjustment may it will be a ring signaling notification/result.

Number 1 and number 2 in the present invention proposed signaling of type integrated signaling format (or information element format) can be constructed by. I.e., while same signaling format, its signaling type number 1 and number 2 contents can be distinguished from/identified by.. For example, integrated signaling format number 2/type number 1 is of particular bits of identification signaling type can function (for example, centric speed and position in benefit metric information a number 1 type signaling only semantic the coating layer has an number 2 type signaling in benefit metric information to register has a bit matched with special is set to a value by number 2 type signaling may be loaded with display being a ring, ).

Furthermore, each hypothesis number 1 or number 2 CoMP, index-process CSI CoMP according that hypothesis each transport of network node may comprise an information. I.e., specific CSI-process assumed CoMP network of nodes when respective transmit powers level (includes whether muting), precoding information, etc. can be constitute the information hypothesis CoMP. Wherein, in a network index-process CSI uniquely identified value at a in (i.e., network-wise (NW) index defined as) can be. Furthermore, constituting a-process CSI NZP CSI-RS index and also each of index CSI-IM NW-NZP-CSI-RS index and can be defined as index NW-CSI-IM.

Furthermore, each hypothesis said CoMP, are used to identify network node CoMP corresponding ID (for example, cell ID), along with information "CoMP hypothesis set" can be defined as. I.e., any for cell information specifies whether hypothesis-CoMP said number 1 or number 2 can be includes signaling type.
