Abstract: front page image
(EN)The present invention relates to a wireless communication system and, in particular, to a method and apparatus for transmitting/receiving a feedback trigger frame in a wireless LAN system. The method for transmitting a feedback trigger frame by means of a request station (STA) in a wireless communication system according to one embodiment of the present invention includes the steps of: transmitting the feedback trigger frame including an acknowledgement (ACK) indication field to a response STA; and receiving a feedback frame from the response STA, wherein the ACK indication field can be set as a value indicating a first type associated with ACK, a second type associated with block ACK (BA), a third type associated with no ACK, or a fourth type associated with an ACK other than those of the first, second, and third types.
(FR)La présente invention concerne un système de communication sans fil et, en particulier, un procédé et un appareil d'émission/réception d'une trame de déclenchement de rétroaction dans un système de réseau local sans fil (WLAN). Selon l'invention, le procédé d'émission d'une trame de déclenchement de rétroaction au moyen d'une station de requête (STA) dans un système de communication sans fil d'un mode de réalisation comprend les étapes consistant : à émettre la trame de déclenchement de rétroaction comprenant un champ d'indication d'accusé de réception (ACK) à une STA de réponse ; et à recevoir une trame de rétroaction de la STA de réponse, le champ d'indication d'ACK pouvant être défini comme une valeur indiquant un premier type associé à un ACK, un deuxième type associé à un ACK de bloc (BA), un troisième type n'étant pas associé à un ACK, ou un quatrième type associé à un ACK autre que ceux des premier, deuxième et troisième types.
(KO)본 발명은 무선 통신 시스템에 대한 것으로, 보다 상세하게는 무선랜 시스템에서 피드백 트리거 프레임을 송신/수신하는 방법 및 장치가 개시된다. 본 발명의 일 실시예에 따른 무선 통신 시스템의 요청 스테이션(STA)에서 피드백 트리거 프레임을 전송하는 방법은, ACK 지시(acknowledgement indication) 필드를 포함하는 상기 피드백 트리거 프레임을 응답 STA에게 전송하는 단계; 및 상기 응답 STA으로부터 피드백 프레임을 수신하는 단계를 포함하고, 상기 ACK 지시 필드는, ACK에 관련된 제 1 유형, 블록 ACK(BA)에 관련된 제 2 유형, ACK 없음(No ACK)에 관련된 제 3 유형, 또는 상기 제 1 유형, 상기 제 2 유형 또는 상기 제 3 유형 이외의 유형에 관련된 제 4 유형 중의 하나를 지시하는 값으로 설정될 수 있다.
