1. A user equipment (UE), comprising:
a transceiver configured to receive, via higher layer signaling, a first configuration of a plurality of transmission configuration indication (TCI) states and a second configuration of a control resource set (CORESET); and
a processor operably coupled to the transceiver, the processor configured to:
perform physical downlink control channel (PDCCH) monitoring on the CORESET based on two TCI states of the CORESET,
identify a beam failure detection (BFD) reference signal (RS) set including RS indexes in RSs associated with the two TCI states, and
detect beam failure based on the BFD RS set.
