Abstract:
(EN) The present invention relates to an apparatus and method for performing random access in a wireless communication system. The method for performing random access in the terminal of the present invention includes the steps of: transmitting a random access preamble to a base station in a sub-serving cell; starting a random access window; receiving a downlink control channel on which downlink control information including a new data indicator indicating that a new transmission or retransmission of a random access response message is mapped from the base station in the sub-serving cell; and determining whether the random access response message is received in the period of the random access window, and whether the random access response message is successfully received through a physical downlink common channel in the sub-serving cell.
(FR) La présente invention concerne un appareil et un procédé permettant d'effectuer un accès aléatoire dans un système de communication sans fil. Le procédé pour effectuer un accès aléatoire dans le terminal de la présente invention comprend les étapes consistant à : transmettre un préambule d'accès aléatoire à une station de base dans une cellule de desserte secondaire ; lancer une fenêtre d'accès aléatoire ; recevoir un canal de contrôle descendant sur lequel des informations de contrôle dans le sens descendant comprenant un indicateur de nouvelles données indiquant une nouvelle transmission ou une retransmission d'un message de réponse pour l'accès aléatoire sont mises en correspondance, à partir de la station de base dans la cellule de desserte secondaire ; et déterminer si le message de réponse pour l'accès aléatoire est reçu dans la période de la fenêtre d'accès aléatoire, et si le message de réponse pour l'accès aléatoire est reçu avec succès par l'intermédiaire d'un canal physique commun descendant dans la cellule de desserte secondaire.
(KO) 본 발명은 무선 통신 시스템에서 랜덤 액세스의 수행장치 및 방법에 관한 것이다. 이러한 본 명세서는 랜덤 액세스 프리앰블을 부서빙셀상에서 상기 기지국으로 전송하는 단계, 랜덤 액세스 윈도우를 시작하는 단계, 랜덤 액세스 응답 메시지의 신규 전송 또는 재전송을 지시하는 신규 데이터 지시자를 포함하는 하향링크 제어정보가 맵핑된 물리 하향링크 제어채널을 상기 부서빙셀상에서 상기 기지국으로부터 수신하는 단계, 및 상기 랜덤 액세스 응답 메시지가 상기 랜덤 액세스 윈도우의 구간내에서 수신되는지 여부와, 상기 신규 데이터 지시자가 신규 전송을 지시하는지 여부를 기반으로, 상기 랜덤 액세스 응답 메시지가 상기 부서빙셀상의 물리 하향링크 공용채널을 통해 성공적으로 수신되는지를 판단하는 단계를 포함하는 단말에 의한 랜덤 액세스의 수행방법을 개시한다.
