Limited duty cycle fdd system

Номер: US20120002578A1

Автор: Peter Gaal, Tingfang JI

Принадлежит: Qualcomm Inc

Acknowledgment bundling has been defined for Long Term Evolution (LTE) Time Division Duplex (TDD) systems due to asymmetric DL/UL partitioning. In the case of Frequency Division Duplex (FDD) with a limited uplink (UL) duty cycle, there may be asymmetry associated with a downlink transmission and an associated uplink acknowledgment. For example, there may be a physical downlink shared channel (PDSCH) and a physical uplink control channel (PUCCH) hybrid automatic repeat request acknowledgment (HARQ-ACK) asymmetry. Interference between downlink and uplink transmissions may be a factor contributing to the limited UL duty cycle in an FDD system. For an FDD system having a limited mobile transmission duty cycle, both DL and UL performance may be significantly degraded without proper mitigation techniques. According to certain embodiments of the present disclosure, various HARQ and scheduling techniques may be utilized for minimizing loss due to the limited UL duty cycle.

A communication device transmits frames having a long preamble under a state where signals will not reach unless a beam pattern is formed, thereby enabling access control based on physical carrier sense, and under a state where signals will sufficiently reach without a beam pattern being formed transmits frames having a shorter preamble, thereby suppressing transmission overhead. Also, a beam pattern and preamble type are decided based on transmission/reception history of access control following CSMA/CA procedures.

High Performance and Low Complexity Scheduling Method for Adaptive Resource Usage in OFDMA Wireless Relay Networks

Номер: US20120026932A1

Автор: Karthikeyan Sundaresan, Sampath Rangarajan

Принадлежит: NEC Laboratories America Inc

A method for scheduling transmissions in wireless network includes receiving information ranging from conventional data to real-time streaming applications into a basestation of an OFDMA wireless relay network and scheduling transmission of the information from the basestation by influencing adaptive frame segmentation and access hop reuse in the transmission of the information for achieving higher transmission flow of the information, Where the scheduling is formulated as an integer program, the scheduling includes solving a linear programming relaxation of the integer program and rounding to integral allocations with allocation to at least one of a subset of wireless users and subsets of relays in the network for obtaining frame segmentation and reuse. Where the scheduling is formulated by following a bisection approach to guide adaptation of the frame segmentation, the scheduling determines a subset of users with maximum flow per unit resource for a given frame segmentation and the resulting flow from current and previous scheduling being used to guide adaptation of frame segmentation towards convergence.

Disclosed are channel management methods in a multicarrier structure in a mobile communication system. Uplink (UL) and downlink (DL) channel management methods in a carrier aggregation environment are used as the channel management methods. In DL, a base station determines a component carrier (CC) of an unstable radio channel state, stops data retransmission by the CC, and notifies a terminal of retransmission stop. In UL, the base station determines a CC of an unstable radio channel state and instructs the terminal to stop data retransmission by the CC, and the terminal stops the data retransmission and initializes a retransmission buffer. Using the channel management methods in the mobile communication system employing the multicarrier structure, an increase in the number of unnecessary retransmissions is prevented, so that unnecessary retransmission and power consumption of the terminal can be reduced and the waste of radio resources and the degradation of base station performance due to unnecessary retransmission can be prevented.

The invention relates to methods for scheduling of uplink transmission and generating transport blocks according to multiple received uplink assignments Furthermore, the invention is also related to the implementation of these methods in hardware and software. To propose strategies for generating plural transport blocks within a given time constraint, the invention introduces prioritization of the uplink assignments, so that multiple uplink assignments can be ranked in the mobile terminal in a priority order. The prioritization of the uplink assignments is used to determine the order in which the individual transport blocks corresponding to the uplink assignments are filled, respectively how the data of different logical channels is multiplexed to the transport blocks for transmission in the uplink. Another aspect of the invention is to suggest joint logical channel procedures that operate on virtual transport blocks accumulated from the received uplink assignments. One or more such joint logical channel procedure can be performed in parallel.

Embodiments of the invention provide coexistence among independent networks through active superframe interleaving. Network hubs and devices exchange signals over a selected channel only during active superframes of their network. Network hubs broadcast coexistence information during their active superframes. A hub of network B desiring to use the selected channel first attempts to fit its active superframes within network A's inactive superframes, if available. If network A is not providing inactive superframes, then the network B hub determines whether network A is willing to coexist using active superframe interleaving on the channel. If so, the network B hub sends an interleave request message to the network A hub, which may accept the message and send back an interleave response message. The network A hub then offers new inactive superframes, and the network B hub adapts the transmissions and receptions of network B to fit within these inactive superframes.

That is, the present invention introduces a resource arrangement method which allows different users to share the same resource, without even using an SDMA, and a method for informing the fractional RB allocation and how to use the same. A method for introducing multiplexation into an RB and changing the RE arrangement is proposed to support the downlink fractional RB allocation. A method for changing the RE arrangement is also proposed to support the uplink fractional RB allocation. According to the present invention, to provide a consistent service with a small amount of traffic generated as in the VoIP, resources of a smaller amount than a single RB can be used for a terminal with a good channel state. In the present invention, the occupancy of resources for the terminals of an excellent channel state is reduced so that the capacity of the VoIP can be improved.

It is described a method for partitioning radio transmission resources within a telecommunication network. The method includes (a) preparing a handover of a user equipment from a source access point being assigned to a source side of the telecommunication network to a target access point being assigned to a target side of the telecommunication network, (b) transferring a pre-announcement message from the source side to the target side indicating the handover, wherein the pre-announcement message is indicative for the amount of data traffic being associated with the user equipment, and (c) partitioning the radio transmission resources on the target side based on the pre-announcement message. It is further described a source side network element and a target side network element for controlling a partitioning of radio transmission resources within a telecommunication network. Furthermore, a computer program for controlling the above described method is described.

A position of a device within a cluster of multiple devices is determined and stored in a memory. An uplink radio resource is mapped from a downlink radio resource in dependence on the determined position of the device within the cluster of multiple devices. In an embodiment the respective uplink and downlink radio resource is a PUCCH and PDCCH of a cellular network, and the cluster is a D2D network. In one embodiment the device position is an index j which is used to offset from a predetermined mapping pattern. In another embodiment the position of the device corresponds to an individual field of a transmission on the PDCCH and the mapping is in dependence on a bit value in the individual field.
