1. A method performed by a terminal in a wireless communication system, the method comprising:
detecting a beam failure for a special cell (SpCell); and
in case that a physical random access channel (PRACH) occasion is not configured for an active uplink (UL) bandwidth part (BWP) of the SpCell,
switching the active UL BWP to an initial UL BWP and an active downlink (DL) BWP to an initial DL BWP; and
performing a random access procedure for a beam failure recovery of the SpCell based on a first beam failure recovery configuration of the initial UL BWP.
