Transmission point indication in coordinated multi-point system

摘要

Embodiments of the present disclosure describe devices, methods, computer-readable media and systems configurations for transmission point indication in a coordinated multipoint (CoMP) system. A 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 a first base station of the CoMP measurement set that is scheduled for communications 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.

主权项

1. An apparatus to be employed by a user equipment (UE), the apparatus comprising:
communications circuitry to:
receive, via radio resource control (RRC) signaling, common reference signal (CRS) parameters associated with individual evolved Node Bs (eNBs) of a coordinated multipoint (CoMP) measurement set including a plurality of eNBs, wherein the CRS parameters include a number of CRS antenna ports, a CRS frequency shift, and a transmission point index of the individual eNBs; andreceive a downlink control information (DCI) message including a transmission point index corresponding to a first eNB of the CoMP measurement set; and mapping circuitry coupled with the communications circuitry, the mapping circuitry to produce a physical downlink shared channel (PDSCH) mapping pattern based on the received CRS parameters associated with the first eNB; wherein the CRS parameters are received from a second eNB of the CoMP measurement set, and wherein the DCI message is received from the first or second eNB.
