SELECTING ANTENNA PORTS FOR REFERENCE SIGNAL BASED ON MOBILITY AND CSI FEEDBACK IN WIRELESS NETWORKS WITH DISTRIBUTED REMOTE RADIO HEADS

摘要

Wireless networks may include remote radio heads (RRHs) for extending the coverage of a macro cell. The macro cell may be connected to the RRHs, for example, by optical fiber, and there may be negligible latency between the macro cell and the RRHs. As a user equipment (UE) moves within the macro cell, or between other macro cells, mobility procedures followed by the UE may vary based on the release of the UE (e.g., Rel-8/9, Rel-10, or Rel-11 and beyond). The macro cell may handle all the scheduling within the cell, for itself and the RRHs.
