Abstract
(EN)
The present invention relates to a method for operating a first communication node in a wireless local area network (WLAN) supporting a multi-link operation, comprising the steps of: setting a first transmit window size of a first link for transmitting a plurality of frames to a second communication node; transmitting the plurality of frames through the first link; when the state of a channel detected through channel sensing in the second link is an idle state, setting a transmit opportunity (TXOP) in the channel; and when the transmit opportunity is set, performing an agreement with the second communication node on the size of a second transmit window for transmitting the plurality of frames. Therefore, it is possible to improve the performance of a communication system.

La présente invention concerne un procédé de commande d’un premier nœud de communication dans un réseau local sans fil (WLAN) prenant en charge une opération multi-liaison. Le procédé comprend les étapes consistant à : définir une taille d’une première fenêtre de transmission d'une première liaison pour transmettre une pluralité de trames à un second nœud de communication ; transmettre la pluralité de trames via la première liaison ; lorsque l'état d'un canal détecté au moyen d’une détection de canal dans la seconde liaison est un état de repos, définir une opportunité de transmission (TXOP) dans le canal ; et lorsque l'opportunité de transmission est définie, réaliser un accord avec le second nœud de communication sur la taille d'une seconde fenêtre de transmission pour transmettre la pluralité de trames. La solution selon l'invention permet d'améliorer les performances d'un système de communication.

본 발명은 다중 링크(multi-link) 동작을 지원하는 WLAN(Wireless Local Area Network)에서 제1 통신 노드의 동작 방법으로, 제2 통신 노드로 복수의 프레임들을 전송하기 위한 제1 링크의 제1 전송 윈도우 크기(Transmit window size)를 설정하는 단계, 상기 제1 링크를 통하여 상기 복수의 프레임들을 전송하는 단계, 제2 링크에서의 채널 센싱을 통하여 검출된 채널의 상태가 아이들(Idle) 상태인 경우, 상기 채널에 전송 기회(Transmit Opportunity, TXOP)를 설정하는 단계 및 상기 전송 기회가 설정된 경우, 상기 제2 통신 노드와 상기 복수의 프레임들을 전송하기 위한 제2 전송 윈도우 크기를 합의(agreement)하는 단계를 포함한다. 따라서 통신 시스템의 성능을 향상시킬 수 있다.
