Abstract
(EN)
A method by which a first device performs wireless communication is presented. The method can comprise the steps in which: a first device performs at least one sidelink transmission to a second device; negative acknowledgement (NACK) information related to the at least one sidelink transmission is received from the second device; and whether to transmit a message for requesting a retransmission resource is determined on the basis of a preset latency time threshold value and a remaining latency budget related to the at least one sidelink transmission.
(FR)
La présente invention concerne un procédé par lequel un premier dispositif réalise une communication sans fil. Le procédé peut comprendre les étapes consistant : à effectuer, par le biais d'un premier dispositif, au moins une transmission de liaison latérale vers un second dispositif ; à recevoir des informations d'accusé de réception négatif (NACK) relatives auxdites transmissions de liaison latérale du second dispositif ; et à déterminer s'il faut transmettre un message afin de demander une ressource de retransmission sur la base d'une valeur seuil de temps de latence prédéfinie et d'un budget de latence restant associé auxdites transmissions de liaison latérale.

제 1 장치가 무선 통신을 수행하는 방법이 제안된다. 상기 방법은, 제 1 장치가 제 2 장치에게 적어도 하나의 사이드링크 전송을 수행하고, 상기 제 2 장치로부터 상기 적어도 하나의 사이드링크 전송과 관련된 NACK(negative acknowledgement) 정보를 수신하고, 상기 적어도 하나의 사이드링크 전송과 관련된 남은 레이턴시 버짓(latency budget) 및 사전 설정된 지연 시간 임계 값에 기반하여, 재전송 자원을 요청하기 위한 메시지를 전송할 지 여부를 결정하는 단계를 포함할 수 있다.
