Autonomous quasi co-location status redefinition by receiver in coordinated multipoint downlink

摘要

User Equipment, UE (30), in a wireless radiocommunication network (10) supporting Coordinated Multi-Point, CoMP, transmissions may autonomously adopt an assumption of the quasi co-located (QCL) status of two (or more) antenna ports that is different from the default QCL status defined or signaled by the network (10), in response to one or more estimates of certain operating parameter values. The altered QCL status assumption allows the UE (30) to correct parameter estimates more accurately, and/or to reduce complexity in the parameter estimation correction.
