Title (EN) CHANNEL ACCESS METHOD IN WIRELESS COMMUNICATION SYSTEM AND APPARATUS THEREFOR
(FR) PROCÉDÉ D'ACCÈS À UN CANAL DANS UN SYSTÈME DE COMMUNICATION SANS FIL ET APPAREIL ASSOCIÉ
(KO) 무선 통신 시스템에서 채널 액세스 방법 및 이를 위한 장치
Abstract: front page image
(EN)A channel access method in a wireless communication system and an apparatus for supporting the same are disclosed. Particularly, the method comprises the steps of: transmitting a beacon frame containing a traffic indication map (TIM); and receiving a power pave (PS)- poll frame within a PS-Poll section set in a station (STA), to which downlink data is designated by the TIM, from the STA, wherein the PS-Poll section can be set differently for each STA within the entire PS-Poll section set in all STAs, to which downlink data is designated by the TIM.
(FR)La présente invention concerne un procédé d'accès à un canal dans un système de communication sans fil et un appareil destiné à supporter ledit procédé. En particulier, le procédé comprend les étapes consistant à : transmettre une trame de balise contenant une carte d'indication de trafic (TIM) ; et recevoir d'une station (STA) une trame d'interrogation d'économie d'énergie (PS) dans une section PS-Poll (section d'interrogation d'économie d'énergie) définie dans la station (STA), pour laquelle des données de liaison descendante sont désignées par la carte TIM, la section PS-Poll pouvant être définie différemment pour chaque station STA dans la section PS-Poll complète définie dans toutes les stations STA auxquelles des données de liaison descendante sont désignées par la carte TIM.
(KO)본 발명에서는 무선 통신 시스템에서 채널 액세스 방법 및 이를 지원하는 장치가 개시된다. 구체적으로, TIM(Traffic Indication Map)을 포함하는 비콘 프레임을 전송하는 단계 및 TIM에 의하여 하향링크 데이터가 지정된 스테이션(STA: Station)으로부터 STA에 설정된 PS(Power Save)-Poll 구간 내에서 PS-Poll 프레임을 수신하는 단계를 포함하고, PS-Poll 구간은 TIM에 의하여 하향링크 데이터가 지정된 모든 STA에게 설정된 총 PS-Poll 구간 내에서 각 STA 별로 상이하게 설정될 수 있다.
