1. A user equipment (UE) in a wireless communication system, the UE comprising:

a transceiver; and

a controller configured to:

receive, from a base station via the transceiver, configuration information including a set of one or more transmission configuration indicator (TCI) states and a parameter indicating whether downlink control information (DCI) for TCI state indication is enabled,

receive, from the base station via the transceiver, DCI including a TCI field which indicates a TCI state in the set of one or more TCI states,

identify whether the DCI is with downlink assignment or is for the TCI state indication, and

apply the indicated TCI state for a reception of at least one of a physical downlink shared channel (PDSCH) and a physical downlink control channel (PDCCH), based on the identification.
