Abstract
(EN) The present disclosure relates to a wireless communication system, and specifically provides a method and a device therefor, the method comprising: receiving first configuration information for transmitting a sounding reference signal (SRS); performing a channel access procedure (CAP) on the basis of the first configuration information; acquiring a time period for the SRS transmission from an Nth symbol on the basis of a successful CAP in the Nth symbol; performing the SRS transmission within the time period; transmitting, within the time period, second configuration information for triggering positioning reference signal (PRS) transmission in at least one base station included in a cell group; and receiving a PRS from the at least one base station within the time period.
(FR) La présente invention concerne un système de communication sans fil, et concerne spécifiquement un procédé et un dispositif associé, le procédé comprenant: la réception de premières informations de configuration pour la transmission d'un signal de référence de sondage (SRS); la réalisation d'une procédure d'accès au canal (CAP) sur la base des premières informations de configuration; l'acquisition d'une période de temps pour la transmission de SRS à partir d'un nième symbole sur la base d'une CAP réussie dans le nième symbole; la réalisation de la transmission du SRS dans la période de temps; la transmission, dans la période de temps, de secondes informations de configuration pour déclencher une transmission de signal de référence de positionnement (PRS) dans au moins une station de base incluse dans un groupe de cellules; et la réception d'un recevoir un PRS provenant de la ou des stations de base dans la période de temps.
(KO) 본 개시는 무선 통신 시스템에 관한 것으로서, 구체적으로 SRS (sounding reference signal) 전송을 위한 제1 구성 정보를 수신하고, 상기 제1 구성 정보에 기반하여 CAP (channel access procedure)를 수행하고, N번째 심볼에서 CAP에 성공한 것에 기반하여 N번째 심볼부터 상기 SRS 전송을 위한 시간 구간 획득하고, 상기 시간 구간 내에서 상기 SRS 전송을 수행하고, 상기 시간 구간 내에서 셀 그룹에 포함된 적어도 하나의 기지국의 PRS (positioning reference signal) 전송을 트리거하기 위한 제2 구성 정보를 전송하고, 상기 시간 구간 내에서 상기 적어도 하나의 기지국으로부터 PRS를 수신하는 방법 및 이를 위한 장치가 제공된다.
