1. A method performed by a user equipment (UE) in a wireless communication system, the method comprising:
receiving configuration information for transmission configuration indication (TCI) states;
receiving a media access control (MAC) control element (CE) indicating a subset of the TCI states;
receiving downlink control information (DCI) indicating a TCI state selection;
in case that two TCI states are indicated from the subset by at least one of the MAC CE and DCI, determining, according to the TCI state selection, whether to apply one of the two TCI states to all antenna ports for a physical downlink shared channel (PDSCH), or to apply the two TCI states respectively to two sub-groups of antenna ports for the PDSCH; and
receiving the PDSCH based on the determination.
