WIRELESS COMMUNICATION METHOD WIRELESS COMMUNICATION APPARATUS AND COMPUTER READABLE STORAGE MEDIUM FOR SELECTING ANTENNA PORTS IN WIRELESS NETWORKS WITH REMOTE RADIO HEADS

摘要

The wireless networks may include remote radio heads (RRHs) for extending the coverage of the macrocell. The macrocell may be connected to the RRHs by, for example, an optical fiber, and there may be a negligible latency between the macrocell and the RRHs. As the user equipment UE moves within the macrocell or between other macrocells, the mobility procedures that the UE follows follow the release of the UE (e.g., Rel-8/9, Rel-10, And more). A macro cell can handle all scheduling within a cell, for itself and RRHs. The method includes: receiving CSI feedback from a user equipment based on CSI feedback; selecting one or more antenna ports for transmitting reference signals, wherein one or more of the antenna ports are connected to at least antenna ports of the base station And determining whether to update the selection of one or more antenna ports based at least in part on the change or mobility in the location of the user equipment.
