Classification: CPC H | IPC H

Claim 0:
1. A method performed by a user equipment (UE) in a wireless communication system, the method comprising:
receiving information related to a cell group that includes two configurations for PUCCH transmission;
receiving information including two Beam Failure Detection-Reference Signal sets (BFD-RS sets);
detecting a beam failure based on a beam failure instance (BFI) counter being equal to or greater than a beam failure instance max count,
wherein the BFI counter is set for each of the two BFD-RS sets; and
transmitting a Physical Uplink Control Channel (PUCCH) related to the beam failure, based on one of the two configurations,
wherein the two BFD-RS sets are related to a serving cell which is a Primary Cell (PCell), a Primary Secondary Cell (PSCell) or a Secondary Cell (SCell),
wherein, based on 1) the two BFD-RS sets being related to the PCell or the PSCell and 2) the two configurations including a first configuration associated with a first BFD-RS set of the two BFD-RS sets and a second configuration associated with a second BFD-RS set of the two BFD-RS sets:
based on the BFI counter of the first BFD-RS set being equal to or greater than the beam failure instance max count, the first configuration is used for the transmission of the PUCCH related to the beam failure,
based on the BFI counter of the second BFD-RS set being equal to or greater than the beam failure instance max count, the second configuration is used for the transmission of the PUCCH related to the beam failure.
