Abstract: front page image
(EN)According to an embodiment of the present invention, a method in which a station (STA) operates in a power saving (PS) mode in a wireless LAN system supporting a high efficiency physical layer protocol data unit (HE PPDU) comprises the steps of: receiving a trigger frame for allocating a resource for uplink multi-user (UL MU) PPDU transmission; and determining whether the STA shifts into a doze state, on the basis of the trigger frame, wherein the STA determines to shift into the doze state when the resource is not allocated to the STA through the trigger frame, and a time interval in which the STA operates in the doze sate may be determined on the basis of a PS mode field included in the trigger frame.
(FR)Selon un mode de réalisation de la présente invention, un procédé dans lequel une station (STA) fonctionne en mode d'économie d'énergie (PS) dans un système de réseau local (LAN) sans fil prenant en charge une unité de données de protocole de couche physique à efficacité élevée (HE PPDU) comprend les étapes consistant : à recevoir une trame de déclenchement pour attribuer une ressource pour une transmission PPDU multi-utilisateur à liaison montante (UL MU); et à déterminer le fait de savoir si la STA passe dans un état de veille, sur la base de la trame de déclenchement, la STA déterminant de passer en état de veille lorsque la ressource n'est pas attribuée à la STA à travers la trame de déclenchement, et un intervalle de temps, dans lequel la STA fonctionne en état de veille peut être déterminé sur la base d'un champ de mode PS compris dans la trame de déclenchement.
(KO)본 발명의 일 실시예에 HE PPDU(high efficiency physical layer protocol data unit)를 지원하는 무선 랜 시스템에서 스테이션(STA)이 PS(power saving) 모드로 동작하는 방법은, UL MU(uplink multi-user) PPDU 전송을 위한 자원을 할당하는 트리거 프레임을 수신하는 단계; 및 상기 트리거 프레임에 기초하여 도즈 상태(doze state)로 천이할지 여부를 결정하는 단계를 포함하되, 상기 STA은, 상기 트리거 프레임을 통해서 상기 STA에 자원이 할당되지 않은 경우, 상기 도즈 상태로 천이하는 것으로 결정하되, 상기 STA이 상기 도즈 상태로 동작하는 시간은, 상기 트리거 프레임에 포함된 PS 모드 필드에 기초하여 결정될 수 있다.
