Abstract: front page image
(EN)A method by which a station (STA) receives a Multi-STA BlockAck (M-BA) frame in a wireless LAN system supporting an OFDMA, according to one embodiment of the present invention, comprises the steps of: transmitting an uplink multi-user (ULMU) frame on the basis of a trigger frame; receiving an M-BA frame based on an OFDMA physical layer protocol data unit (PPDU) including an SIG B field; and acquiring a data stream including an ACK/NACK for the STA from the OFDMA PPDU-based M-BA frame, wherein the STA acquires the data stream according to an indication of a user field identified by a predetermined ID among a plurality of user fields included in the SIG B field, and the data stream indicated by the user field identified by the predetermined ID can be equally allocated to other STAs performing the UL MU transmission on the basis of the trigger frame.
(FR)La présente invention concerne, selon un mode de réalisation, un procédé par lequel une station (STA) reçoit une trame d'accusé de réception de bloc multi-STA (M-BA) dans un système de réseau local (LAN) sans fil prenant en charge l'accès multiple par répartition orthogonale de la fréquence (OFDMA), qui comprend les étapes consistant à : envoyer une trame multiutilisateur de liaison montante (MU UL) sur la base d'une trame de déclenchement ; recevoir une trame M-BA basée sur une unité de données de protocole de couche physique (PPDU) OFDMA comprenant un champ SIG B ; et acquérir un flux de données comprenant un accusé de réception/accusé de réception négatif (ACK/NACK) pour la STA à partir de la trame M-BA basée sur la PPDU OFDMA, la STA acquérant le flux de données conformément à une indication d'un champ utilisateur identifié par un identificateur (ID) prédéfini parmi une pluralité de champs utilisateurs inclus dans le champ SIG B, et le flux de données indiqué par le champ utilisateur identifié par l'ID prédéfini pouvant être attribué d'une manière égale à d'autres STA effectuant la transmission MU UL sur la base de la trame de déclenchement.
(KO)본 발명의 일 실시예에 따라서 OFDMA를 지원하는 무선랜 시스템에서 스테이션(STA)이 M-BA(Multi-STA BlockAck) 프레임을 수신하는 방법은, 트리거 프레임에 기초하여 UL MU(uplink multi-user) 프레임을 전송하는 단계; SIG B 필드를 포함하는 OFDMA PPDU(physical layer protocol data unit) 기반의 M-BA 프레임을 수신하는 단계; 및 상기 OFDMA PPDU 기반의 M-BA 프레임으로부터 상기 STA에 대한 ACK/NACK을 포함하는 데이터 스트림을 획득하는 단계를 포함하되, 상기 STA은, 상기 SIG B 필드에 포함된 다수의 사용자 필드들 중 소정의 ID에 의해 식별된 사용자 필드의 지시에 따라서 상기 데이터 스트림을 획득하고, 상기 소정의 ID에 의해 식별된 사용자 필드가 지시하는 상기 데이터 스트림은, 상기 트리거 프레임에 기초하여 UL MU 전송을 수행한 다른 STA들에도 동일하게 할당될 수 있다.
