Title (EN) METHOD AND APPARATUS FOR TRANSMITTING FRAME IN WIRELESS LAN
(FR) PROCÉDÉ ET APPAREIL POUR ÉMETTRE UNE TRAME DANS UN RÉSEAU LOCAL (LAN) SANS FIL
(KO) 무선랜에서 프레임을 전송하는 방법 및 장치
Abstract:
(EN) A method for transmitting a frame in a wireless LAN according to an embodiment of the present specification includes: receiving an RTS frame for medium protection from an AP, the RTS frame including common information commonly allocated to a plurality of user STAs and STA-specific information individually allocated to the plurality of user STAs, and a step of the common information including an indicator for indicating any one of a static bandwidth operation and a dynamic bandwidth operation; a step of forming a CTS frame in response to the RTS frame according to the indicator; and a step of transmitting the CTS frame to the AP.
(FR) Un procédé d’émission d’une trame dans un LAN sans fil selon un mode de réalisation de la présente invention comprend les étapes suivantes : réception d’une trame RTS pour la protection de support en provenance d’un AP, la trame RTS contenant des informations communes attribuées de manière commune à une pluralité de STA d’utilisateur et des informations spécifiques à des STA attribuées de manière individuelle à la pluralité de stations d’utilisateur, et une étape des informations communes contenant un indicateur servant à indiquer une opération quelconque parmi une opération de largeur de bande statique et une opération de largeur de bande dynamique ; une étape de formation d’une trame CTS en réponse à la trame RTS à partir de l’indicateur ; et une étape d’envoi de la trame CTS à l’AP.
(KO) 본 명세서의 일 실시 예에 따른 무선랜에서 프레임을 전송하는 방법은, 매체 보호를 위한 RTS 프레임을 AP로부터 수신하되, RTS 프레임은 복수의 사용자 STA을 위해 공통으로 할당된 공통 정보 및 복수의 사용자 STA을 위해 개별적으로 할당된 STA-특정(STA-specific) 정보를 포함하고, 공통 정보는 정적(static) 대역동작(bandwidth operation) 및 동적(dynamic) 대역동작 중 어느 하나를 지시하는 지시자(indicator)를 포함하는 단계, 지시자에 따라 RTS 프레임에 대한 응답으로 CTS 프레임을 구성하는 단계 및 AP로 CTS 프레임을 전송하는 단계를 포함한다.
