Abstract:
(EN) Provided are a method and a device for transmitting a feedback frame in a wireless LAN system. Particularly, a first wireless station receives, from a second wireless station, a feedback request field including an LTF. The first wireless station configures feedback information on a wireless channel corresponding to a preset frequency band by using the feedback request field. The first wireless station transmits the feedback information to the second wireless station .
(FR) L’invention concerne un procédé et un dispositif pour transmettre une trame de rétroaction dans un système de réseau local (LAN) sans fil. En particulier, une première station sans fil reçoit, à partir d’une seconde station sans fil, un champ de requête de rétroaction comprenant un champ d’apprentissage long (LTF). La première station sans fil configure des informations de rétroaction sur un canal sans fil correspondant à une bande de fréquences préétablie par utilisation du champ de requête de rétroaction. La première station sans fil transmet les informations de rétroaction à la seconde station sans fil.
(KO) 무선랜 시스템에서 피드백 프레임을 송신하는 방법 및 장치를 제공한다. 구체적으로, 제1 무선 스테이션은 제2 무선 스테이션으로부터, LTF를 포함하는 피드백 요청 필드를 수신한다. 제1 무선 스테이션은 피드백 요청 필드를 사용하여 기설정된 주파수 대역에 상응하는 무선 채널에 관한 피드백 정보를 구성한다. 제1 무선 스테이션은 상기 피드백 정보를 상기 제2 무선 스테이션으로 송신한다.
