Abstract
(EN)
Proposed is a method for a first device to perform wireless communication. The method can include a step of: receiving a plurality of first physical sidelink control channels (PSCCHs) or a plurality of first physical sidelink shared channels (PSSCHs); determining the priorities of a plurality of first physical sidelink feedback channels (PSFCHs) related to either the plurality of first PSCCHs or the plurality of first PSSCHs; and transmitting a hybrid automatic repeat request (HARQ) feedback through at least one first PSFCH among the first plurality of the first PSFCHs on the basis of the priorities of the plurality of first PSFCHs.
(FR)
L'invention concerne un procédé permettant à un premier dispositif d'exécuter une communication sans fil. Le procédé peut comprendre les étapes consistant à : recevoir une pluralité de premiers canaux de commande de liaison latérale physique (PSCCH) ou une pluralité de premiers canaux partagés de liaison latérale physique (PSSCH) ; déterminer les priorités d'une pluralité de premiers canaux de rétroaction de liaison latérale physique (PSFCH) se rapportant à la pluralité de premiers PSCCH ou à la pluralité de premiers PSSCH ; et transmettre une rétroaction de requête automatique de répétition hybride (HARQ) par l'intermédiaire d'au moins un premier PSFCH de la première pluralité de premiers PSFCH sur la base des priorités de la pluralité de premiers PSFCH.

제 1 장치가 무선 통신을 수행하는 방법이 제안된다. 상기 방법은, 복수의 제 1 PSCCH(physical sidelink control channel) 또는 복수의 제 1 PSSCH(physical sidelink shared channel)를 수신하고, 상기 복수의 제 1 PSCCH 또는 상기 복수의 제 1 PSSCH와 관련된 복수의 제 1 PSFCH(physical sidelink feedback channel)의 우선 순위를 결정하고, 상기 복수의 제 1 PSFCH의 우선 순위에 기반하여 상기 복수의 제 1 PSFCH 중 적어도 하나의 제 1 PSFCH를 통해, HARQ(hybrid automatic repeat request) 피드백을 전송하는 단계를 포함할 수 있다.
