1. A user equipment (UE), comprising:
a transceiver configured to:
receive first information for indicating one of: (i) a joint transmission configuration indicator (TCI) state configuration for downlink (DL) and uplink (UL) or (ii) a separate TCI state configuration for each of the DL and the UL,
receive second information on a first set of TCI states for the joint TCI state configuration or for the DL,
receive third information on a second set of TCI states for the UL in case that the first information indicates the separate TCI state configuration,
receive a message for activating at least one TCI state among the first set or the second set, via medium access control-control element (MAC CE) signaling, the at least one activated TCI state being mapped to one or more codepoints of a TCI field in downlink control information (DCI) based on the message, and
receive the DCI including the TCI field; and
a processor operably coupled to the transceiver and configured to identify a TCI state to apply to at least one of a DL channel or a UL channel,
wherein the transceiver is further configured to receive the DL channel or transmit the UL channel based on the identified TCI state, and
wherein, in case that a number of the one or more codepoints mapped to the at least one activated TCI state is one, the identified TCI state is the at least one activated TCI state.
