Abstract
(EN)
In a wireless local area network (LAN) system, a station (STA) can receive a first signal from a first shared access point (AP) and a second signal from a second shared AP. The STA can check a channel state on the basis of the first and second signals. The STA can transmit a signal that requests sounding from a sharing AP on the basis of the channel state.
(FR)
L'invention concerne un système de réseau local sans fil (LAN) dans lequel une station (STA) peut recevoir un premier signal provenant d'un premier point d'accès (AP) partagé et un second signal provenant d'un second AP partagé. La STA peut vérifier un état de canal sur la base des premier et second signaux. La STA peut émettre un signal qui demande un sondage à partir d'un AP de partage sur la base de l'état de canal.
(KO)
무선랜(Wireless Local Area Network) 시스템에서, STA(station)은 제1 셰어드(shared) AP(access point)로부터 제1 신호를, 제2 셰어드 AP로부터 제2 신호를 수신할 수 있다. 상기 STA은 상기 제1 및 제2 신호를 기초로 채널 상태를 확인할 수 있다. 상기 STA은 상기 채널 상태를 기초로 셰어링(sharing) AP에게 사운딩을 요청하는 신호를 전송할 수 있다.
