    摘要： Systems and methodologies are described that facilitate identifying resources upon which an acknowledgment can be sent or received in a wireless communication environment that leverages coordinated multi-point (CoMP). The resources can be identified based upon a criterion that can be identifiable to a non-anchor cell base station (as well as an anchor cell base station, a mobile device, etc.). The criterion can be an identifier corresponding to a mobile device, where the identifier maps to a predetermined set of resources. Examples of the identifier can include a media access control identifier (MACID), a cell radio network temporary identifier (C-RNTI), a short C-RNTI, etc. Further, the criterion can be physical resources corresponding to a transmission, where the acknowledgment is responsive to the transmission. Moreover, the acknowledgment can be sent or received in connection with a cooperation technique (e.g., joint transmission via inter-site packet sharing, cooperative beamforming, cooperative silence, . . . ).

    摘要： A communication system comprises evolved base nodes (eNBs) communicating via an over-the-air (OTA) link with low mobility user equipment (UE). A network can utilize the eNBs for cooperative beam shaping for interference nulling based upon a number of factors UE (e.g., coordinated multi-point (CoMP) optimization for feedback, quality of service (QoS), fairness, etc.). The UE advantageously transmits multiple description coding (MDC) that supports a determination by the eNBs that coherent channel conditions (e.g., frequency and/or time invariance) exists for combining feedback reports to realize reduced quantization error. In addition, the MDC feedback reports still support incoherent channel states in which each report can be used individually for interference nulling/beamforming. MDC can be performed with one codebook or a plurality of codebooks.

    摘要： Techniques for supporting Coordinated MultiPoint (CoMP) transmission are described. For CoMP transmission, multiple cells may simultaneously send one or more data streams to one or more UEs on the same time-frequency resources based on short-term channel feedback from at least one UE to at least two cells. In an aspect, a semi-static configuration may be used by a set of cells for CoMP transmission to a UE. The semi-static configuration may indicate resource elements available to the set of cells to send CoMP transmission to the UE. The available resource elements may be determined based on a maximum number of TDM control symbols for all cells in the set and resource elements used for cell-specific reference signals by the cells in the set. A cell in the set may send data on the available resource elements to the UE for the CoMP transmission.

    摘要： Systems and methodologies are described herein that facilitate Hybrid Automatic Repeat Request (H-ARQ) scheduling and coordination in a wireless communication system. As described herein, a network node capable of cooperation with other nodes for communication to respective users can coordinate a cooperation strategy across nodes based on a H-ARQ protocol to be utilized for a given user. In the case of a synchronous H-ARQ protocol, communication can be scheduled as described herein such that initial transmissions to a user are conducted cooperatively and re-transmissions are conducted without inter-node cooperation. In the case of a H-ARQ protocol utilizing persistent assignments, transmission intervals can be calculated and utilized based on application latency requirements, backhaul link latency, or other factors. In the case of an asynchronous H-ARQ protocol, repeat transmissions can be coordinated in a similar manner to initial transmissions or conducted without inter-node cooperation based on latency sensitivity of an associated application.

    摘要： A communication system comprises evolved base nodes (eNBs) communicating via an over-the-air (OTA) link with low mobility user equipment (UE). A network can utilize the eNBs for cooperative beam shaping for interference nulling based upon a number of factors UE (e.g., coordinated multi-point (COMP) optimization for feedback, quality of service (QoS), fairness, etc.). The UE advantageously transmits adaptive rate and payload channel state feedback, trading accuracy versus delay based upon mobility of the UE. Channel coherence across a transmission interval (frequency and/or time invariance) provides an opportunity with sufficiently low mobility for transmitting a larger accuracy feedback report over one or more feedback reports for decoding at the eNB. Reduced quantization error can be realized via multi-level coding, one codebook multiple description coding (MDC), and use of N-best code representations from one codebook with MDC.
