Title
(EN) METHOD AND DEVICE FOR DISCOVERY RESOURCE ALLOCATION IN WIRELESS COMMUNICATION SYSTEM
(FR) PROCÉDÉ ET DISPOSITIF POUR ALLOCATION DE RESSOURCES DE RECHERCHE DANS UN SYSTÈME DE COMMUNICATION SANS FIL
(KO) 무선 통신 시스템에서 디스커버리 자원 할당 방법 및 장치
Abstract
(EN) The present disclosure relates to a method for performing initial beam configuration by a first terminal in a wireless communication system, and the method may comprise the steps of: transmitting a discovery message on the basis of a plurality of transmission beams in a first section among discovery sections; receiving a response message from a second terminal on the basis of a plurality of reception beams in a second section among the discovery sections; and performing beam alignment with the second terminal on the basis of the response message, wherein the plurality of transmission beams and the plurality of receptions beams are mapped in a one-to-one manner.
(FR) La présente divulgation concerne un procédé permettant de réaliser une configuration de faisceau initiale au moyen d'un premier terminal dans un système de communication sans fil, et le procédé peut comprendre les étapes consistant à : transmettre un message de recherche sur la base d'une pluralité de faisceaux de transmission dans une première section parmi des sections de recherche ; recevoir un message de réponse d'un second terminal sur la base d'une pluralité de faisceaux de réception dans une seconde section parmi les sections de recherche ; et réaliser un alignement de faisceau avec le second terminal sur la base du message de réponse, la pluralité de faisceaux de transmission et la pluralité de faisceaux de réception étant mappées d'une manière biunivoque.
(KO) 본 개시는 무선 통신 시스템의 제 1 단말이 초기 빔 설정을 수행하는 방법에 있어서, 디스커버리 구간 중 제 1 구간에서 복수 개의 송신 빔에 기초하여 디스커버리 메시지를 전송하는 단계, 디스커버리 구간 중 제 2 구간에서 복수 개의 수신 빔에 기초하여 응답 메시지를 제 2 단말로부터 수신하는 단계 및 응답 메시지에 기초하여 제 2 단말과 빔 정렬을 수행하는 단계를 포함하되, 복수 개의 송신 빔과 복수 개의 수신 빔은 일대일로 매핑될 수 있다.
