The present disclosure relates to a method and apparatus for transmitting an uplink channel in a wireless communication system. The method for transmitting an uplink channel by a terminal may comprise the steps of: determining a transmission resource of at least one physical uplink control channel (PUCCH) to transmit uplink control information (UCI); determining a transmission resource of a first physical uplink shared channel (PUSCH) to be transmitted to a first transmission and reception point (TRP), the transmission resource overlapping at least one PUCCH in the time domain; determining a transmission resource of a second PUSCH to be transmitted to a second TRP, the transmission resource overlapping at least one PUCCH in the time domain; multiplexing the UCI to at least one of the first PUSCH and the second PUSCH; transmitting the first PUSCH to the first TRP; and transmitting the second PUSCH to the second TRP. La présente divulgation concerne un procédé et un appareil permettant de transmettre un canal de liaison montante dans un système de communication sans fil. Le procédé permettant de transmettre un canal de liaison montante par un terminal peut faire appel aux étapes suivantes de : détermination d'une ressource de transmission d'au moins un canal de commande de liaison montante physique (PUCCH) afin de transmettre des informations de commande de liaison montante (UCI) ; détermination d'une ressource de transmission d'un premier canal partagé de liaison montante physique (PUSCH) à transmettre à un premier point de transmission et de réception (TRP), la ressource de transmission chevauchant au moins un PUCCH dans le domaine temporel ; détermination d'une ressource de transmission d'un second PUSCH à transmettre à un second TRP, la ressource de transmission chevauchant au moins un PUCCH dans le domaine temporel ; multiplexage des UCI vers au moins l'un du premier PUSCH et du second PUSCH ; transmission du premier PUSCH au premier TRP ; et transmission du second PUSCH au second TRP. 본 개시는 무선 통신 시스템에서 상향 링크 채널을 전송하는 방법 및 장치에 관한 것으로, 단말이 상향 링크 채널을 전송하는 방법은, UCI(uplink control information)를 전송하기 위한 적어도 하나의 PUCCH (physical uplink control channel)의 전송 자원을 결정하는 단계, 적어도 하나의 PUCCH와 시간 자원 상에서 중첩되는, 제1 TRP(transmission and reception point)로 전송할 제1 PUSCH (physical uplink shared channel)의 전송 자원을 결정하는 단계, 적어도 하나의 PUCCH와 시간 자원 상에서 중첩되는, 제2 TRP로 전송할 제2 PUSCH의 전송 자원을 결정하는 단계, 제1 PUSCH와 제2 PUSCH 중, 적어도 하나의 PUSCH에 UCI를 다중화(multiplexing)하는 단계, 제1 PUSCH를 제1 TRP로 전송하는 단계, 및 제2 PUSCH를 제2 TRP로 전송하는 단계를 포함할 수 있다.
