Abstract

Embodiments of the present disclosure describe devices, methods, computer-readable media and system configurations for transmission point indication in a coordinated multipoint (CoMP) system. User equipment (UE) may receive common reference signal (CRS) parameters associated with individual base stations of a CoMP measurement set. The UE may also receive a transmission point index corresponding to the first base station of the CoMP measurement set that is scheduled for communication with the UE. A mapping module of the UE may produce a physical downlink shared channel (PDSCH) mapping pattern based on the CRS parameters associated with the scheduled base station.
