According to one embodiment of the present application, a method for transmitting a physical uplink control channel (PUCCH) by a terminal in a wireless communication system comprises a step of receiving setting information associated with a PUCCH, and a step of transmitting the PUCCH on the basis of the setting information. The PUCCH is transmitted from a specific PUCCH resource selected from among overlapped PUCCH resources. The specific PUCCH resource is characterized by being associated with beam failure recovery (BFR). Selon un mode de réalisation de la présente invention, un procédé de transmission d'un canal de commande physique de liaison montante (PUCCH), par un terminal dans un système de communication sans fil, comprend une étape de réception d'informations de réglage associées à un PUCCH, et une étape de transmission du PUCCH sur la base des informations de réglage. Le PUCCH est transmis à partir d'une ressource PUCCH spécifique sélectionnée parmi des ressources PUCCH se chevauchant. La ressource PUCCH spécifique est caractérisée en ce qu'elle est associée à une récupération de défaillance de faisceau (BFR). 본 명세서의 일 실시예에 따른 무선 통신 시스템에서 단말이 물리 상향링크 제어 채널(Physical Uplink Control Channel, PUCCH)을 전송하는 방법은 물리 상향링크 제어 채널(Physical Uplink Control Channel, PUCCH)과 관련된 설정 정보를 수신하는 단계 및 상기 설정 정보에 기반하여 상기 PUCCH를 전송하는 단계를 포함한다. 상기 PUCCH는 중첩된 PUCCH 자원들 중에서 결정된 특정 PUCCH 자원(specific PUCCH resource)에서 전송된다. 상기 특정 PUCCH 자원은 빔 실패 복구(beam failure recovery, BFR)와 관련된 것을 특징으로 한다.
