Abstract
(EN)
A method and device for transmitting a frame in a wireless LAN system is proposed. Specifically, a first STA transmits, to a second STA, a link measurement request frame requesting TPC information. The first STA receives, from the second STA, a link measurement report frame transmitted as a response to the link measurement request frame. The link measurement request frame includes a TPC configuration field. The TPC configuration field includes a first subfield and a second subfield. The first subfield includes information as to whether the link measurement request frame is to be transmitted through a channel having been subjected to channel aggregation. The second subfield includes information on the number of transmit chains to be used in transmission of the link measurement request frame. The number of transmit chains is an even number if the link measurement request frame is transmitted through a channel having been subjected to channel aggregation.

La présente invention concerne un dispositif et un procédé d'émission d'une trame dans un système LAN sans fil. Spécifiquement, une première STA transmet, à une seconde STA, une trame de demande de mesure de liaison demandant des informations de TPC. La première STA reçoit, en provenance de la seconde STA, une trame de rapport de mesure de liaison transmise en réponse à la trame de demande de mesure de liaison. La trame de demande de mesure de liaison comprend un champ de configuration TPC. Le champ de configuration TPC comprend un premier sous-champ et un second sous-champ. Le premier sous-champ comprend des informations indiquant si la trame de demande de mesure de liaison doit être transmise par l'intermédiaire d'un canal ayant été soumis à une agrégation de canal. Le second sous-champ comprend des informations sur le nombre de chaînes de transmission à utiliser dans la transmission de la trame de demande de mesure de liaison. Le nombre de chaînes de transmission est un nombre pair si la trame de demande de mesure de liaison est transmise par l'intermédiaire d'un canal ayant été soumis à une agrégation de canal.

무선랜 시스템에서 프레임을 전송하는 방법 및 장치가 제안된다. 구체적으로, 제1 STA은 TPC 정보를 요청하는 링크 측정 요청 프레임을 제2 STA으로 전송한다. 제1 STA은 제2 STA으로부터 링크 측정 요청 프레임에 대한 응답으로 전송된 링크 측정 보고 프레임을 수신한다. 링크 측정 요청 프레임은 TPC 구성 필드를 포함한다. TPC 구성 필드는 제1 서브필드 및 제2 서브필드를 포함한다. 제1 서브필드는 링크 측정 요청 프레임이 채널 어그리게이션(channel aggregation)이 수행된 채널을 통해 전송되는지 여부에 대한 정보를 포함한다. 제2 서브필드는 링크 측정 요청 프레임의 전송에 사용되는 전송 체인(Transmit chain)의 수에 대한 정보를 포함한다. 링크 측정 요청 프레임이 채널 어그리게이션이 수행된 채널을 통해 전송되면, 전송 체인의 수는 짝수이다.
