Disclosed in the present specification is a method for operating in a TXOP power save mode in a wireless LAN system. In particular, a first station receives an MU-RTS frame from a second station during a TXOP. When the AID of the first station is not included in the MU-RTS frame, the first station determines shifting to a doze state for the remaining period of the TXOP. La présente invention concerne un procédé de fonctionnement dans un mode d'économie d'énergie TXOP dans un système de réseau local sans fil. En particulier, une première station reçoit une trame MU-RTS en provenance d'une seconde station pendant une TXOP. Lorsque l'AID de la première station n'est pas inclus dans la trame MU-RTS, la première station détermine le passage à un état de repos pour la période restante de la TXOP. 본 명세서는 무선 랜 시스템에서 TXOP 파워 세이브 모드로 동작하는 방법을 제안한다. 구체적으로, 제1 스테이션은 제2 스테이션으로부터 TXOP 동안 MU-RTS 프레임을 수신한다. MU-RTS 프레임에 제1 스테이션의 AID가 없다면, 제1 스테이션은 TXOP의 남은 구간 동안 도즈 상태로 천이를 결정한다.
