Abstract:
A method for performing a beam failure recovery procedure in a wireless communication system according to an embodiment of the present disclosure, the method performed by a user equipment (UE) includes receiving configuration information related to the BFR, receiving a downlink reference signal (DL RS) based on the configuration information, detecting a beam failure based on measurement for the DL RS, and transmitting a request message for the BFR. The request message for the BFR is transmitted based on a PUCCH resource related to a scheduling request (SR). 1) The PUCCH resource related to the SR is one of a plurality of PUCCH resources configured for the beam failure recovery, and 2) the beam failure is based on being related to one or more cells: the PUCCH resource related to the SR is a specific PUCCH resource determined based on a preconfigured criterion among the plurality of PUCCH resources.
