Abstract:
(EN) An uplink transmission method for a terminal supporting a short transmission time interval (TTI) length in a wireless communication system according to one embodiment of the present invention is performed by the terminal and may comprise the steps of: receiving downlink control information including an uplink grant; and if a transmission time point of an uplink signal corresponding to the uplink grant overlaps a transmission time point of a semi-persistent (SPS) uplink signal, when a TTI length of a first channel, through which the uplink signal corresponding to the uplink grant is to be transmitted, is longer than a TTI length of a second channel through which the SPS uplink signal is to be transmitted, transmitting an uplink signal through only the second channel among the first channel and the second channel at the transmission time point.
(FR) Selon la présente invention, un procédé d'émission de liaison montante pour un terminal prenant en charge une longueur d'intervalle de temps d'émission court (TTI) dans un système de communication sans fil selon un mode de réalisation de la présente invention est exécuté par le terminal et peut comprendre les étapes consistant : à recevoir des informations de commande de liaison descendante comprenant un octroi de liaison montante ; et si un point de temps d'émission d'un signal de liaison montante correspondant à l'octroi de liaison montante chevauche un point de temps d'émission d'un signal de liaison montante semi-persistant (SPS), lorsqu'une longueur de TTI d'un premier canal, par l'intermédiaire duquel le signal de liaison montante correspondant à l'octroi de liaison montante doit être émis, est plus longue qu'une longueur de TTI d'un second canal par l'intermédiaire duquel le signal de liaison montante SPS doit être émis, à émettre un signal de liaison montante par l'intermédiaire uniquement du second canal parmi le premier canal et le second canal au point de temps d'émission.
(KO) 본 발명의 일 실시예에 따른 무선 통신 시스템에서 짧은 TTI(transmission time interval) 길이를 지원하는 단말을 위한 상향링크 전송 방법에 있어서, 상기 방법은 단말에 의해 수행되며, 상향링크 승인을 포함하는 하향링크 제어 정보를 수신하는 단계 및 상기 상향링크 승인에 대응하는 상향링크 신호의 전송 시점과 SPS(semi-persistent) 상향링크 신호의 전송 시점이 중첩하면, 상기 상향링크 승인에 대응하는 상향링크 신호가 전송될 제1 채널의 TTI 길이가 상기 SPS 상향링크 신호가 전송될 제2 채널의 TTI 길이보다 긴 경우, 상기 전송 시점에서 상기 제1 채널 및 상기 제2 채널 중 상기 제2 채널 상에서만 상향링크 신호 전송을 수행하는 단계를 포함할 수 있다.
