摘要： Briefly, in accordance with one or more embodiments, mobile station or user equipment receives pilot signals from two or more infrastructure nodes in a distributed antenna system, and calculates phase or timing information, or combinations thereof, from the pilot signals. The mobile station feeds back the phase or timing information, or combinations thereof, to the infrastructure nodes, and then receives one or more subsequent transmissions from the infrastructure nodes with phase shift or timing adjustments, or combinations thereof, calculated by the infrastructure nodes and applied to the spatial streams transmitted by the infrastructure nodes.

摘要： Embodiments herein provide a wireless communication system including a user equipment (UE) and a plurality of base stations (e.g., evolved NodeBs (eNBs)). The UE may generate feedback information based on channel conditions between the UE and two or more of the plurality of base stations. The UE may transmit the feedback information to one or more of the base stations. Two or more of the plurality of base stations may contemporaneously send different data streams to the UE, the data streams having properties based at least in part on the respective feedback information. The UE may decouple and decode the data streams from the two or more base stations using multi-antenna techniques.

摘要： In various embodiments, a first base station may communicate with a first user equipment (UE) over a wireless communication channel. The first base station may receive an interference indication from a second base station communicating with a second UE on the same wireless communication channel. In response to the interference indication, the first base station may transmit a request to the first UE for the first UE to send feedback information associated with the wireless communication channel to the first base station for one or more transmission ranks specified by the first base station. The first UE may determine the requested feedback information and transmit the determined feedback information to the first base station. Thereafter, the first base station may reduce a transmission rank of ongoing transmissions to the UE based on the interference indication and the determined feedback information.
