First Claim
Patent Images
1. A method for wireless communications by a user equipment (UE), comprising:
- receiving signaling indicating different reference signal (RS) configurations for a set of base stations participating in Coordinated Multipoint (CoMP) operations to the user equipment (UE), each configuration identifying resources for use by one or more of the base stations in transmitting reference signals;
receiving a downlink transmission in a subframe; and
determining how to perform rate matching for the downlink transmission based on one or more of the RS configurations.
