Abstract
(EN)
An embodiment is a method for performing an operation for a first terminal in a wireless communication system, the method including the steps of: transmitting a PSCCH (Physical Sidelink Control Channel) including SCI (Sidelink Control Information) to a second terminal; and receiving an HARQ (Hybrid Automatic Repeat Request) feedback or a CSI (Channel State Information) report from the second terminal on the basis of the SCI, wherein the SCI includes information indicating that the second terminal is woken up during an OnDuration interval, and information for requesting the HARQ feedback or the SCI report.
(FR)
Selon un mode de réalisation, l'invention concerne un procédé permettant d'effectuer une opération pour un premier terminal dans un système de communication sans fil, le procédé comprenant les étapes suivantes : la transmission d'un canal de commande de liaison latérale physique (PSCCH) comprenant des informations de commande de liaison latérale (SCI) à un second terminal ; et la réception d'une rétroaction de demande de répétition automatique hybride (HARQ) ou d'un rapport d'informations d'état de canal (CSI) du second terminal sur la base des SCI, les SCI comprenant des informations indiquant que le second terminal est réveillé pendant un intervalle de durée d'activation, et des informations pour demander la rétroaction HARQ ou le rapport SCI.
