Abstract:
The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates beyond 4th-Generation (4G) communication system such as long term evolution (LTE). A terminal in a wireless communication system is provided. The terminal includes a transceiver, and at least one processor configured to receive, from a base station (BS), a beam failure recovery configuration comprising at least one reference signal for identifying a candidate beam for the beam failure recovery and associated random access (RA) parameters, identify the candidate beam for the beam failure recovery using the at least one reference signal, and perform a physical random access channel (PRACH) using the at least one reference signal and the associated RA parameters on the candidate beam for the beam failure recovery.
