MULTICASTING METHOD USING RELAY IN MOBILE COMMUNICATIONS NETWORK
The present invention refers to the service method relates to search, for relaying communication between base station and terminal in a mobile communication network for spline to multicasting method are disclosed. Generally, communication system comprises a power generation operation with priority order service-centered, and various multimedia service data service as well as voice gradually and also communication system and for generating power. However voice-centered communications system includes transmission bandwidth is relatively small and, given that the terminals of users service detects that oil is expensive. In addition communication signal controls operations of Internet service request of the user with service of the client from an increase in a communication system can be efficiently number [...] need looking up. The developing agent storing oil of users having degree of broadband Internet service number for efficiently [...] broadband wireless access system are presented. Broadband wireless access system for orthogonal frequency division multiplexing (OFDM: Orthogonal Frequency Division Multiplexing)/(physical channel) method can said method for orthogonal frequency division multiple access (OFDMA: Orthogonal Frequency Division Multiple Access) etc.. I.e., the spatially (subcarrier) broadband wireless access system using physical channel signal by transmitting high rate data transmission process from. In broadband wireless access system the base station channel information (CQI: Channel Quality Indicator) fed back from the terminal by using the data transmissions on a chuck. Decoding transmitted after (decode and forward) relay communication system a high communication rate techniques that can effectively height and increase service area of the communication system are disclosed. IEEE 802. 16J of relay communication system comprises a base station such as decoding transmitted after (decode and forward), relay, terminal body is disclosed. In centralized radio resource managing downlink (Downlink) based communication relay, auxiliary power relay terminal between relay terminal in order to measuring channel quality radio links between message, transmitting a relay base station controller over a same relay this information again to be coated. The base station receives the channel state information between the wireless terminal based on the relay link using relay (modulation and coding scheme level) between a symbol-level modulation and fit smaller than the wireless link to execute the other. Mobile communication system when relay have been introduced, consisting of terminals from a base station is equal to relay is relaying communication between base station and terminal in communication system. The, all base station and a terminal communication between relay relaying but is, terminal or away from the base station, where the terminal is equipped with a radio wave reception sensitivity is low, relay relaying same to be coated. When placing relay, relay and communicating with a base station is below a certain radio resources, access zone (Access zone) communication base station and a terminal region transmits relay communication areas how relay zone (Relay zone) whether or not the door number of dividing flow tides. The service base station (multicasting) data to manner as to give the various users using one resource block, the same data as the user various delivery, currently without assigning the unnecessary overlapping, transmits same resource to be coated. The present invention refers to said door such as number and hydrogen gas is provided which, in mobile communication network of Ethernet, utilizing multicasting relay method which can improve the efficiency of the multicasting [...] pin is a number.

And, base station (100) and relay (200) to determine good channel conditions for access zone, access zone (S703) channel conditions of a reference value and compares a predetermined number 2. Access a zone of reference number 2 is below the channel conditions, a plurality of hierarchies (S705, S707) number 1 scheme. Of multicasting of the present invention number 1 carried out as follows. Base station (100) and a relay (200) transmits data burst frame to front line (S705). Then frame base station (1000) and relay (200) provided by the server access zone (Access zone) for multicasting data burst in the same party terminal transmits (S707). While, access zone is turned off and the channel conditions of number 2, number 2 scheme has a plurality of hierarchies (S709, S711). Of the present invention number 2 of multicasting carried out as follows. Multicasting group terminal and relay (200) base station (100) with data from burst access zone d2. (S709). And, then frame relay (200) is adapted to receive data burst through its access zone multi-party terminal transmits (S711). S701 step, base station (100) and relay (200) provided by the server but a predetermined distance, between terminals themselves of MCS (Modulation and Coding Scheme) within the range of selecting predetermined level differences can be multi-terminal group. In the present invention S707 step or after S711, base station (100) and relay (200) is of constant period and re-establish multicasting group, the multicasting the commands can be reset. As than, in the present invention number 1 scheme is base station (100) relay (200) preceding the data burst frame to be transmitted by a substrate. And, then frame access zone base station (100) and relay (200) have the same position-based wireless resource multicasting data burst to be coated. In this case relay zone of radio resources are is consumed, access zone receiving terminals extending from the base station and relay is in the received data to the suction be diversity (diversity) gain. In the present invention number 2 scheme is base station (100) transmitting in multicasting data burst as well as relay terminal access zone (200) of the housing as receiving method, relay (200) is adapted to receive a next frame of data burst is equal to transmit at its access zone RA. In the case of number 2, will relay a zone of data, while the gain of resources, access zone relay (200) is a web server performs both transmission or reception, multicasting using different resource region should be performed as follows. Therefore, compared to use of resources-mail access zone number 2 scheme is number 1 in 2000. Using the present invention a few extracts more preferred embodiment through a browser but, in the embodiment which includes these exemplary definitive tastes. The present invention is provided with the idea of the present invention and the appended claim consultation NaOCl [...] number out of the variety of changes and modification without rights may be will understand. 100 Base station 200 relay The present invention relates to a multicasting method using a relay in a mobile communications network.
