Abstract:
(EN) The present invention relates to a wireless communication system and, more specifically, provides a method and an apparatus therefor, the method comprising the steps of: detecting one or more SSBs in a cell; acquiring downlink synchronization on the basis of the one or more SSBs; and transmitting a RACH preamble by using a PRACH resource corresponding to the best SSB among the one or more SSBs, wherein the downlink synchronization is acquired on the basis of first SSB index information in each of the SSBs, and the PRACH resource is determined on the basis of second SSB index information configured for the best SSB by the cell.
(FR) La présente invention concerne un système de communication sans fil et, plus spécifiquement, un procédé et un appareil associés, le procédé comprenant les étapes consistant : à détecter un ou plusieurs blocs de séquence de synchronisation (SSB) dans une cellule; à acquérir une synchronisation de liaison descendante sur la base du ou des SSB; et à transmettre un préambule RACH à l'aide d'une ressource PRACH correspondant à la meilleure SSB parmi le ou les SSB, la synchronisation de liaison descendante étant acquise sur la base de premières informations d'index de SSB dans chacun des SSB, et la ressource PRACH étant déterminée sur la base de secondes informations d'index de SSB configurées pour le meilleur SSB par la cellule.
(KO) 본 발명은 무선 통신 시스템에 관한 것으로서, 구체적으로 셀에서 하나 이상의 SSB를 검출하는 단계; 상기 하나 이상의 SSB에 기반하여 하향링크 동기를 획득하는 단계; 및 상기 하나 이상의 SSB 중에서 베스트 SSB에 대응되는 PRACH 자원을 이용하여 RACH 프리앰블을 전송하는 단계를 포함하고, 상기 하향링크 동기는 각 SSB 내의 제1 SSB 인덱스 정보에 기반해 획득되고, 상기 PRACH 자원은 상기 셀에 의해 상기 베스트 SSB에 대해 설정된 제2 SSB 인덱스 정보에 기반하여 결정되는 방법, 및 이를 위한 장치가 제공된다.
