Abstract
(EN) In a wireless local area network (LAN) system, a transmission MLD may comprise a first station (STA) and a second station (STA), wherein the first STA operates in a first link, and the second STA operates in a second link. The transmission MLD may transmit a connection request frame to a reception MLD. The connection request frame may comprise capability information related to whether a restricted basic service set (BSS) mode is supported and information related to use of the restricted BSS mode. The information related to the use of the restricted BSS mode may comprise first information related to an STA which operates in the restricted BSS mode, among STAs included in the transmission MLD. The restricted BSS mode may mean a mode in which monitoring for signal reception is performed on the basis of acquisition of information, from an STA not operating in the restricted BSS mode, by the STA operating in the restricted BSS, the information indicating reception of a signal. The transmission MLD may receive a connection response frame from the reception MLD.
(FR) Dans un système de réseau local sans fil (LAN), un dispositif à liaisons multiples (MLD) de transmission peut comprendre une première station (STA) et une seconde station (STA), la première STA fonctionnant sur une première liaison, et la seconde STA fonctionnant sur une seconde liaison. Le MLD de transmission peut transmettre une trame de demande de connexion à un MLD de réception. La trame de demande de connexion peut comprendre des informations de capacité relatives à la question de savoir si un mode d'ensemble de services de base (BSS) restreint est pris en charge et des informations relatives à l'utilisation du mode BSS restreint. Les informations relatives à l'utilisation du mode BSS restreint peuvent comprendre des premières informations relatives à une STA qui fonctionne dans le mode BSS restreint, parmi des STA incluses dans le MLD de transmission. Le mode BSS restreint peut signifier un mode dans lequel une surveillance pour une réception de signal est effectuée sur la base de l'acquisition d'informations, à partir d'une STA ne fonctionnant pas dans le mode BSS restreint, par la STA fonctionnant dans le BSS restreint, les informations indiquant la réception d'un signal. Le MLD de transmission peut recevoir une trame de réponse de connexion provenant du MLD de réception.
(KO) 무선랜(Wireless Local Area Network) 시스템에서, 송신 MLD는 상기 송신 MLD는 제1 STA(station) 및 제2 STA을 포함하고, 상기 제1 STA은 제1 링크에서 동작하고, 상기 제2 STA은 제2 링크에서 동작할 수 있다. 송신 MLD는 수신 MLD에게 연결 요청 프레임을 전송할 수 있다. 상기 연결 요청 프레임은 제한된 BSS(basic service set) 모드 지원 여부에 관련된 캐퍼빌리티 정보 및 상기 제한된 BSS 모드 사용에 관련된 정보를 포함할 수 있다. 상기 제한된 BSS 모드 사용에 관련된 정보는 상기 송신 MLD에 포함된 STA들 중에서 어떤 STA이 제한된 BSS 모드로 동작하는지에 관련된 제1 정보를 포함할 수 있다. 상기 제한된 BSS 모드는, 상기 제한된 BSS로 동작하는 STA이 제한된 BSS 모드로 동작하지 않는 STA으로부터 신호를 수신하라는 정보를 획득함을 기초로 신호 수신을 위한 모니터링을 수행하는 모드를 의미할 수 있다. 송신 MLD는 수신 MLD로부터 연결 응답 프레임을 수신할 수 있다.
