1. A user equipment (UE), comprising:
a transceiver; and
a processor operably coupled to the transceiver, the processor configured to:
identify first configuration information for at least two beam failure detection (BFD) reference signal (RS) sets each comprising one or more BFD RS resources;
identify second configuration information for at least two new beam identification (NBI) RS sets each comprising one or more NBI RS resources, wherein a one-to-one association exists between the at least two NBI RS sets and the at least two BFD RS sets;
detect, based on a measurement of the one or more BFD RS resources, a beam failure event for one of the at least two BFD RS sets;
identify, based on a measurement of the one or more NBI RS resources, one or more NBI RS resources for a new beam recovery; and
trigger, in response to detection of the beam failure event for the one BFD RS set and identification of the one or more NBI RS resources, a beam failure recovery (BFR) event,
wherein the transceiver is further configured to receive one or more transmission configuration indication (TCI) states for one or more physical downlink control channels (PDCCHs); and
the processor is further configured to determine, based on the one or more TCI states, the one or more BFD RS resources for each of the at least two BFD RS sets.
