Title (EN) METHOD FOR A USER TERMINAL TO RANDOM ACCESS A CARRIER AGGREGATION MOBILE COMMUNICATION SYSTEM
(FR) PROCÉDÉ DESTINÉ À UN TERMINAL UTILISATEUR, POUR UN ACCÈS ALÉATOIRE À UN SYSTÈME DE COMMUNICATION MOBILE À AGRÉGATION DE PORTEUSES
(KO) 반송파 조합 방식 이동통신 시스템에서 단말의 임의접속 방법
Abstract:
(EN) Disclosed is a method by which a user terminal carries out a process for random access to a base station in a carrier aggregation mobile communication system which performs communications using a plurality of component carriers (CCs), and to a terminal device for the method. The method considers an uplink grant signal to be a contention resolution message only when the uplink grant signal is received through a downlink CC which corresponds to the downlink CC used in a random access preamble transmission and/or in a third message transmission, to thereby prevent an erroneous contention resolution process from being ended when the user equipment receives the uplink grant signal from the base station in carrying out a contention-based random access process in a carrier aggregation mobile communication system.
(FR) L'invention concerne un procédé selon lequel un terminal utilisateur effectue un processus pour un accès aléatoire à une station de base dans un système de communication mobile à agrégation de porteuses qui établit des communications à l'aide de plusieurs porteuses, et un dispositif terminal destiné au procédé selon l'invention. Selon ce procédé, on considère qu'un signal d'autorisation de liaison montante est un message de résolution de conflits seulement lorsque le signal d'autorisation de liaison montante est reçu par une liaison descendante CC qui correspond à la liaison descendante CC utilisée dans une transmission de préambule d'accès aléatoire et/ou dans une troisième transmission de message, afin d'éviter l'interruption d'un processus de résolution de conflits erroné lorsqu'un équipement utilisateur reçoit le signal d'autorisation de liaison montante de la station de base dans un processus d'accès aléatoire basé sur les conflits, dans un système de communication mobile à agrégation de porteuses.
(KO) 본 문서는 복수의 구성 반송파(Component Carrier: CC)를 이용하여 통신을 수행하는 반송파 조합(Carrier Aggregation: CA) 방식 이동통신 시스템에서 단말이 기지국에 임의접속 절차를 수행하는 방법 및 이를 위한 단말 장치에 대한 것이다. CA 기술이 적용된 이동통신 시스템에서 단말이 경쟁 기반 임의접속 잘차를 수행함에 있어, 기지국으로부터 상향링크 승인 신호를 수신하였을 때 해당 상향링크 승인 신호가 임의접속 프리엠블 전송 및/또는 제 3 메시지 전송에 이용된 상향링크 CC와 대응 관계를 가지는 하향링크 CC를 통해 수신된 경우에 한하여 이를 충돌 해결 메시지로 간주함으로써 잘못된 충돌 해결 절차 종료를 방지할 수 있다.
