Title (EN) METHOD AND DEVICE FOR PROCESSING UPLINK SIGNAL IN WLAN SYSTEM
(FR) PROCÉDÉ ET DISPOSITIF DE TRAITEMENT D'UN SIGNAL DE LIAISON MONTANTE DANS UN SYSTÈME WLAN
(KO) 무선랜 시스템에서 상향링크 신호를 처리하는 방법 및 장치
Abstract: front page image
(EN)Provided are a method and device for processing an uplink (UL) signal in a WLAN system. An access point (AP) receives a request to send (RTS) frame from one station (STA) among a plurality of STAs, transmits a group identifier (ID) of a group to which STAs for performing UL multi user multiple-input multiple-output (MU-MIMO) transmission together with the one STA, among group IDs of a group to which the one STA belongs, and receives UL signals from the STAs which perform the UL MU-MIMO transmission such that the received UL signals are processed.
(FR)L'invention concerne un procédé et un dispositif de traitement d'un signal de liaison montante (UL) dans un système WLAN. Un point d'accès (AP) reçoit une demande d'émission (RTS) d'une trame à partir d'une station (STA) parmi une pluralité de STA; transmet aux STA, en collaboration avec ladite STA, un identifiant (ID) d'un groupe d'identifiants auquel appartient la STA pour effectuer une transmission UL multi-utilisateurs à entrées multiples-sorties multiples (MU-MIMO); et reçoit des signaux UL des STA qui effectuent la transmission UL MU-MIMO, ce qui permet de traiter les signaux UL reçus.
(KO)무선랜 시스템에서 상향링크(UL; uplink) 신호를 처리하는 방법 및 장치가 제공된다. 접속 포인트(AP; access point)는 복수의 STA들 중 하나의 스테이션(STA; station)으로부터 RTS(request to send) 프레임을 수신하고, 상기 하나의 STA가 속한 그룹의 그룹 ID(identifier) 중 상기 하나의 STA와 함께 UL MU(multi user)-MIMO(multiple-input multiple-output) 전송을 수행할 STA가 속한 그룹의 그룹 ID를 전송하고, 상기 UL MU-MIMO 전송을 수행하는 STA들로부터 UL 신호들을 수신하여 처리한다.
