Summary: | One embodiment of the present invention relates to a method for a first terminal to transmit and receive a sidelink signal in a wireless communication system, the method comprising: a step in which the first terminal determines whether there is a collision in each subchannel within a time window; and a step in which the first terminal transmits collision-related information associated with a result of the determination, wherein the collision-related information includes a signal generated from a K-sparse signal, and the K-sparse signal is a signal in which the number of subchannels, from among all subchannels within the time window, determined to have a collision occurring therein is limited to K.
Un mode de réalisation de la présente invention concerne un procédé permettant à un premier terminal d'émettre et de recevoir un signal de liaison latérale dans un système de communication sans fil, le procédé comprenant: une étape dans laquelle le premier terminal détermine s'il existe une collision dans chaque sous-canal à l'intérieur d'une fenêtre temporelle; et une étape dans laquelle le premier terminal transmet des informations associées à une collision associées à un résultat de la détermination, les informations relatives à une collision comprenant un signal généré à partir d'un signal à faible densité K, et le signal à K clairsemé étant un signal dans lequel le nombre de sous-canaux, parmi tous les sous-canaux à l'intérieur de la fenêtre temporelle, déterminés comme ayant une collision s'y produisant est limité à K
본 발명의 일 실시예는, 무선통신시스템에서 제1 단말이 사이드링크(Sidelink) 신호를 송수신하는 방법에 있어서, 상기 제1 단말이 타임 윈도 내에서 서브채널 별로 충돌 여부를 판단하는 단계; 및 상기 제1 단말이 상기 판단 결과에 관련된 충돌 관련 정보를 전송하는 단계를 포함하며, 상기 충돌 관련 정보는, K-sparse signal로부터 생성된 신호를 포함하며, 상기 K-sparse signal은 상기 타임 윈도 내 모든 서브채널 중 충돌이 발생한 것으로 판단된 서브채널의 개수가 K개로 제한된 신호인, 사이드링크 신호 송수신 방법이다. |
