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.
