Abstract: front page image
(EN)The present invention relates to a method for performing random access in a wireless LAN system and a device for same. To this end, a station receives from an AP a frame comprising resource allocation information for random access and performs backoff, on the basis of a predetermined contention window size, in resources allocated on the basis of the resource allocation information for random access. In addition, the station transmits, at a first point in which a backoff counter reaches 0, a second frame by means of randomly selected resources which have been randomly selected among the resources that have been allocated as specified, wherein the STA performs clear channel assessment (CCA) for the resources that have been allocated on the basis of the resource allocation information for random access and thus controls the transmission of the second frame by means of the randomly selected resources on the basis of a CCA result.
(FR)La présente invention concerne un procédé permettant d'effectuer un accès aléatoire dans un système de réseau local sans fil et un dispositif pour celui-ci. A cet effet, une station (STA) reçoit en provenance d'un point d'accès (AP) une trame comprenant des informations d'allocation de ressources pour un accès aléatoire et effectue, en se basant sur une taille de fenêtre de contention prédéfinie, une réduction de puissance des ressources allouées sur la base des informations d'allocation de ressources pour un accès aléatoire. En outre, la station transmet, au niveau d'un premier point où un compteur de réduction de puissance atteint 0, une seconde trame au moyen de ressources sélectionnées de façon aléatoire qui ont été sélectionnées de manière aléatoire parmi les ressources qui ont été allouées conformément à des spécifications, la STA effectuant l'évaluation de canal libre (CCA) pour les ressources qui ont été allouées en se basant sur les informations d'allocation de ressources pour un accès aléatoire et commandant ainsi la transmission de la seconde trame au moyen des ressources sélectionnées de manière aléatoire sur la base du résultat de la CCA.
(KO)본 문서는 무선랜 시스템에서 랜덤 액세스를 수행하는 방법 및 이를 위한 장치에 대한 것이다. 이를 위해 스테이션은 AP로부터 랜덤 액세스용 자원 할당 정보를 포함하는 프레임을 수신하고, 랜덤 액세스용 자원 할당 정보에 따라 할당된 자원에서 소정 경쟁 윈도우 (Contention Window) 크기에 기반한 백오프를 수행한다. 또한, 스테이션은 백오프의 카운터가 0에 도달한 제 1 시점에서 상술한 바와 같이 할당된 자원 중 임의로 선택된 임의선택자원을 통해 제 2 프레임을 전송하되, STA은 랜덤 액세스용 자원 할당 정보에 따라 할당된 자원에 대한 CCA(Clear Channel Assessment)를 수행하여, 이 CCA 결과에 따라 임의선택자원을 통한 제 2 프레임 전송을 조절하는 것을 특징으로 한다.
