Summary:Disclosed are a method and a device for operating a non-AP station which communicates with an access point (AP). Specifically, a non-AP STA according to the present invention may obtain a transmission opportunity (TXOP) through a back off procedure, and transmit an initiation frame for sharing the obtained TXOP to an AP associated with the non-AP station. The initiation frame may include access category information indicating an access category (AC) according to the back off procedure. Thereafter, the non-AP STA may receive a specific frame for obtaining the TXOP from the associated AP on the basis of the initiation frame. Un procédé et un dispositif pour faire fonctionner une station non AP qui communique avec un point d'accès (AP) sont divulgués. Spécifiquement, une STA non AP selon la présente invention peut obtenir une opportunité de transmission (TXOP) par l'intermédiaire d'une procédure de réduction de puissance, et transmettre une trame d'initiation pour partager la TXOP obtenue à un AP associé à la station non AP. La trame d'initiation peut comprendre des informations de catégorie d'accès indiquant une catégorie d'accès (AC) selon la procédure de réduction de puissance. Ensuite, la STA non AP peut recevoir une trame spécifique pour obtenir la TXOP à partir de l'AP associé sur la base de la trame d'initiation. 본 발명은 AP(access point)와 통신하는 non-AP 스테이션의 동작 방법 및 장치를 개시한다. 구체적으로, 본 발명에 의한 non-AP STA은 백 오프 절차(back off procedure)를 통해서 전송 기회(transmission opportunity: TXOP)을 획득할 수 있으며, 획득된 TXOP를 공유(sharing)하기 위한 개시 프레임(initiate frame)을 상기 non-AP 스테이션과 연관된(associated) AP에게 전송할 수 있다. 개시 프레임은 상기 백 오프 절차에 의한 접속 카테고리(Access Category: AC)를 지시하는 접속 카테고리 정보를 포함할 수 있다. 이후, non-AP STA은 개시 프레임에 기초하여 상기 TXOP를 획득하기 위한 특정 프레임을 상기 연관된 AP로부터 수신할 수 있다.
