Title (EN) METHOD FOR PERFORMING INITIAL ACCESS IN WIRELESS COMMUNICATION SYSTEM, AND APPARATUS THEREFOR
(FR) PROCÉDÉ D'EXÉCUTION D'ACCÈS INITIAL DANS UN SYSTÈME DE COMMUNICATION SANS FIL, ET APPAREIL CORRESPONDANT

Abstract:
(EN) Disclosed are a method for performing an initial access in a wireless communication system, and an apparatus therefor. Specifically, a method by which a terminal performs an initial access comprises the steps of: receiving, from a base station, configuration information indicating one or more physical random access channel (PRACH) configurations; receiving, from the base station, downlink control information including information indicating a specific PRACH configuration among the one or more PRACH configurations, through a physical downlink control channel; and transmitting a preamble and/or data, which are related to the initial access, to the base station through a PRACH on the basis of the specific PRACH configuration.
(FR) L’invention concerne un procédé d'exécution d'un accès initial dans un système de communication sans fil, et un appareil correspondant. De façon plus spécifique, un procédé par lequel un terminal exécute un accès initial comprend les étapes consistant à : recevoir, d'une station de base, des informations de configuration indiquant une ou plusieurs configurations de canal d'accès aléatoire physique (PRACH) ; recevoir, de la station de base, des informations de commande de liaison descendante comprenant des informations indiquant une configuration PRACH spécifique parmi la ou les configurations PRACH, via un canal de commande de liaison descendante physique ; et transmettre un préambule et/ou des données, relatifs à l'accès initial, à la station de base, via un PRACH, sur la base de la configuration PRACH spécifique.
(KO) 본 발명에서는 무선 통신 시스템에서 초기 접속을 수행하는 방법 및 이를 위한 장치가 개시된다. 구체적으로, 단말이 초기 접속을 수행하는 방법에 있어서, 상기 방법은, 기지국으로부터, 하나 이상의 물리 랜덤 액세스 채널(Physical Random Access Channel, PRACH) 설정(configuration)들을 나타내는 설정 정보를 수신하는 과정과, 물리 하향링크 제어 채널(Physical Downlink Control Channel)을 통해, 상기 하나 이상의 PRACH 설정들 중 특정 PRACH 설정을 지시하는 정보를 포함하는 하향링크 제어 정보(Downlink Control Information)를 상기 기지국으로부터 수신하는 과정과, 상기 특정 PRACH 설정에 기반하여, PRACH를 통해, 상기 초기 접속과 관련된 프리앰블(preamble) 또는 데이터(data) 중 적어도 하나를 상기 기지국으로 전송하는 과정을 포함할 수 있다.
