Abstract
(EN)
Proposed are a method and a device for performing joint transmission in a wireless LAN system. Specifically, an M-AP selects first to third S-APs which are to participate in joint transmission. The M-AP manages a link with the first to third S-APs to share first information between the first to third S-APs. The M-AP performs joint transmission to an STA through the first to third S-APs on the basis of the first information.
(FR)
La présente invention concerne un procédé et un dispositif destinés à réaliser une transmission conjointe dans un système LAN sans fil. Plus précisément, un M-AP sélectionne des premier à troisième S-AP qui doivent participer à la transmission conjointe. Le M-AP gère une liaison avec les premier à troisième S-AP afin de partager des premières informations entre les premier à troisième S-AP. Le M-AP réalise une transmission conjointe vers une STA par l'intermédiaire des premier à troisième S-AP sur la base des premières informations.
(KO)
무선랜 시스템에서 조인트 전송을 수행하는 방법 및 장치가 제안된다. 구체적으로, M-AP는 조인트 전송에 참여할 제1 내지 제3 S-AP를 선택한다. M-AP는 제1 내지 제3 S-AP 간의 제1 정보를 공유하기 위해 제1 내지 제3 S-AP와의 연결을 관리한다. M-AP는 제1 정보를 기반으로 제1 내지 제3 S-AP를 통해 STA에게 조인트 전송을 수행한다.
