Transmission point indication in coordinated multi-point system
First Claim
1. One or more non-transitory computer-readable media having instructions, stored thereon, that when executed cause a user equipment (UE) to:
- receive, via radio resource control (RRC) signaling, a plurality of parameter sets, wherein individual parameter sets of the plurality of parameter sets include a number of common reference signal (CRS) antenna ports, a CRS frequency shift and an index of a transmission point;
detect a physical downlink control channel (PDCCH) that includes a 2-bit value corresponding to the index of the transmission point scheduled for transmission and indicating one of the individual parameter sets;
identify the individual parameter set indicated by the 2-bit value; and
decode a physical downlink shared channel (PDSCH) based on the identified individual parameter set.

Abstract
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.
