CPC H04L 5/0053 (2013.01) [H04W 72/042 (2013.01)] | 18 Claims |
1. A method of deriving a Quasi-CoLocation (QCL) assumption in multi-panel transmission for a user equipment (UE), the method comprising:
reporting, to a network, capabilities of supporting a multi-transmit-receive point (TRP) operation for supporting simultaneous reception from multiple TRPs and a panel-specific default beam for at least one physical downlink shared channel (PDSCH) reception;
obtaining a plurality of control resource set (CORESET) groups from the network of a wireless communication system;
determining a default QCL assumption for demodulation reference signal (DM-RS) port(s) of the at least one 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 indicating the default QCL assumption; and
applying the default QCL assumption for reception of the DM-RS port(s) of the at least one PDSCH.
