Abstract
(EN) An uplink transmission and reception method and device in wireless communication system are disclosed. A method by which a terminal performs uplink transmission in a wireless communication system, according to one embodiment of the present disclosure, may comprise the steps of: receiving configuration information related to a plurality of sounding reference signal (SRS) resource sets; receiving downlink control information (DCI), which indicates at least one from among a first SRS resource set, a second SRS resource set, or the first SRS resource set and the second SRS resource set and includes information indicating at least one SRS resource in the indicated at least one SRS resource set; and performing the uplink transmission on the basis of the indicated at least one SRS resource.
(FR) Sont divulgués ici un procédé et un dispositif de transmission et de réception en liaison montante dans un système de communication sans fil. Un procédé permettant à un terminal d'effectuer une transmission en liaison montante dans un système de communication sans fil, selon un mode de réalisation de la présente divulgation, peut comprendre les étapes consistant à : recevoir des informations de configuration relatives à une pluralité d'ensembles de ressources de signal de référence de sondage (SRS) ; recevoir des informations de commande de liaison descendante (DCI), qui indiquent au moins l'un parmi un premier ensemble de ressources SRS, un second ensemble de ressources SRS, ou le premier ensemble de ressources SRS et le second ensemble de ressource SRS, et comprenant des informations indiquant au moins une ressource SRS dans l'au moins un ensemble de ressources SRS indiqué ; et effectuer la transmission en liaison montante sur la base de l'au moins une ressource SRS indiquée.
(KO) 무선 통신 시스템에서 상향링크 송수신 방법 및 장치가 개시된다. 본 개시의 일 실시예에 따른 무선 통신 시스템에서 단말이 상향링크 전송을 수행하는 방법은: 복수의 사운딩 참조 신호(sounding reference signal, SRS) 자원 세트와 관련된 설정 정보를 수신하는 단계 제1 SRS 자원 세트, 제2 SRS 자원 세트, 또는 상기 제1 SRS 자원 세트 및 상기 제2 SRS 자원 세트 중 적어도 하나를 지시하고, 상기 지시된 적어도 하나의 SRS 자원 세트에서 적어도 하나의 SRS 자원을 지시하는 정보를 포함하는, 다운링크 제어 정보(downlink control information, DCI)를 수신하는 단계 및 상기 지시된 적어도 하나의 SRS 자원에 기초하여 상기 상향링크 전송을 수행하는 단계를 포함할 수 있다.
