Patent ID: 11683142

Abstract:
A method of deriving a Quasi-CoLocation (QCL) assumption for a user equipment (UE) in multi-panel transmission is disclosed. The method comprises obtaining a plurality of control resource set (CORESET) groups from a network of the wireless communication system, determining a default QCL assumption for demodulation reference signal (DM-RS) port(s) of at least one physical downlink share channel (PDSCH), reception scheduled by a scheduling physical downlink control channel (PDCCH) according to a CORESET of one of the plurality of CORESET groups when a time offset between a reception of downlink control information (DCI), in the scheduling PDCCH and the at least one PDSCH reception is less than a threshold, wherein at least one of the plurality of CORESET groups includes at least one CORESET for indicating a QCL assumption, and applying the default QCL assumption for reception of the DM-RS port(s) of the at least one PDSCH.
