Claim 0:
1. A method performed by a terminal in a wireless communication system, the method comprising:
receiving, from a base station, configuration information on a reference signal for identifying beam failure recovery (BFR);
determining that the BFR for a serving cell associated with the base station is triggered based on the configuration information and is not cancelled;
identifying whether an uplink shared channel (UL-SCH) resource is available for a new transmission;
in case that the UL-SCH resource is available for the new transmission, identifying whether the UL-SCH resource is able to accommodate a non-truncated BFR medium access control (MAC) control element (CE) plus a subheader for the non-truncated BFR MAC CE;
in case that the UL-SCH resource is not able to accommodate the non-truncated BFR MAC CE plus the subheader for the non-truncated BFR MAC CE, identifying whether the UL-SCH resource is able to accommodate a truncated BFR MAC CE plus a subheader for the truncated BFR MAC CE; and
in case that the UL-SCH resource is not able to accommodate the truncated BFR MAC CE plus the subheader for the truncated BFR MAC CE, triggering a scheduling request (SR) for the BFR for the serving cell.
