INTERACTION OF SOUNDING REFERENCE SIGNALS WITH UPLINK CHANNELS FOR COORDINATED MULTI POINT OPERATIONS

摘要

Certain aspects of the present disclosure provide methods and apparatus for facilitating interaction of sounding reference signals (SRS) with uplink channels while supporting coordinated multipoint (CoMP) transmission/reception operations. One method generally includes receiving from one or more nodes participating in the CoMP operations with a user equipment (UE) signaling indicating at least one of cell specific SRS configurations or formats for uplink channels and determining based at least in part upon the signaling whether at least one last symbol of a subframe is available for transmitting one or more of the uplink channels from the UE.
