Abstract
A method of a user equipment (UE) for a beam failure recovery procedure in a wireless communication system is provided. The method comprises receiving, from a base station (BS), at least one beam failure detection reference signal (RS) and at least one new candidate beam RS over a downlink channel; identifying a set of RS resources including an index for the at least one beam failure detection RS; identifying a set of RS resources including an index for the at least one new candidate beam RS; identifying a dedicated control-resource set (CORESET) received from the BS for a beam failure recovery request; transmitting, to the BS, the beam failure recovery request associated with a quality measurement of the at least one beam failure detection RS over a physical random access channel (PRACH); and receiving, from the BS, a beam failure response in response to the beam failure recovery request based on the dedicated CORESET indicated to the UE.
