发明名称 Method and apparatus for separable channel state feedback in a wireless communication system
摘要 Systems and methodologies are described herein that facilitate the generation and use of separable, hierarchical channel state feedback in a wireless communication system. As described herein, in the event that multiple network nodes cooperate to conduct downlink transmissions to a network user, channel state feedback as reported by the network user can be separated into intra-node feedback relating to per-node channel conditions and inter-node feedback relating to relative phase and/or amplitude between channels corresponding to respective nodes. Further, a network user can select to report intra-node feedback and/or inter-node feedback based on network instructions, a cooperation strategy to be utilized by respective network nodes, or the like. As additionally described herein, respective codebooks on which inter-node and intra-node channel feedback is based can be configured to convey information relating to a partial channel description and/or to vary based on resource units (e.g., sub-bands, resource blocks, etc.) utilized for downlink communication.

主权项 1. A method, comprising: analyzing parameters relating to both mobility of an associated user equipment (UE) unit and network conditions; selecting a downlink coordination strategy to be utilized across network nodes for communication with the associated UE unit based on the analyzed parameters; and instructing the associated UE unit to provide at least one of an intra-node channel state feedback or an inter-node channel state feedback to the network nodes based at least in part on the selected downlink coordination strategy.
