Abstract: front page image
(EN) The present invention relates to a method for transmitting and receiving a traffic indication map in a wireless communication system, and to an apparatus for same. More particularly, the method includes a step of transmitting a traffic indication map (TIM) to a station (STA) through a beacon frame, wherein the TIM can include a bitmap field configured of one or more sub-block bitmaps for indicating whether buffered downlink data exists for an STA which is grouped to one or more sub-blocks, and a block control field indicating an encoding scheme of the bitmap field.
(FR) La présente invention concerne un procédé d'émission et de réception d'une carte d'indication de trafic dans un système de communication sans fil, et un appareil correspondant. Plus particulièrement, le procédé comprend une étape d'émission d'une carte d'indication de trafic (TIM) vers une station (STA) par l'intermédiaire d'une trame de balise, la TIM pouvant comprendre un champ de table de bits constitué d'une ou de plusieurs tables de bits de sous-blocs destinées à indiquer si des données de liaison descendante en mémoire tampon existent pour une STA groupée à un ou plusieurs sous-blocs, et un champ de commande de bloc indiquant un schéma d'encodage du champ de table de bits.
(KO) 본 발명에서는 무선 통신 시스템에서 트래픽 지시 맵(TIM: Traffic Indication Map)을 송수신하는 방법 및 이를 지원하는 장치가 개시된다. 구체적으로, 비콘 프레임을 통해 TIM을 STA에게 전송하는 단계를 포함하고, TIM은 하나 이상의 서브 블록으로 그룹핑된 STA에 대하여 버퍼된 하향링크 데이터의 존재 여부를 지시하기 위한 하나 이상의 서브-블록 비트맵으로 구성되는 비트맵(bitmap) 필드와 비트맵 필드의 인코딩 방법을 지시하는 블록 제어(block control) 필드를 포함할 수 있다.
