Abstract
(EN)
According to various embodiments, a multi-link device including a first STA and a second STA may receive, via the first STA, at least one PPDU within a transmission opportunity (TXOP) configured in a first link. While the at least one PPDU is received, the state of the second STA may be set to a doze state. The multi-link device may receive, via the first STA, a first control frame for the truncation of the TXOP. The multi-link device may change the state of the second STA from the doze state to an awake state on the basis of the first control frame.
(FR)
Selon divers modes de réalisation de l'invention, un dispositif à liaisons multiples comprenant une première STA et une deuxième STA peut recevoir, par l'intermédiaire de la première STA, au moins une PPDU dans une opportunité de transmission (TXOP) configurée dans une première liaison. Pendant que la ou les PPDU sont reçues, l'état de la deuxième STA peut être réglé comme étant un état de sommeil. Le dispositif à liaisons multiples peut recevoir, par l'intermédiaire de la première STA, un premier cadre de commande pour la troncature de la TXOP. Le dispositif à liaisons multiples peut modifier l'état de la deuxième STA de l'état de sommeil à un état activé en fonction de la première trame de commande.
(KO)
다양한 실시 예들에 따르면, 제1 STA 및 제2 STA을 포함하는 멀티 링크 디바이스는 제1 STA을 통해 제1 링크에서 설정된 TXOP(transmission opportunity) 내에서 적어도 하나의 PPDU를 수신할 수 있다. 적어도 하나의 PPDU가 수신되는 동안, 제2 STA의 상태가 수면(doze) 상태로 설정될 수 있다. 멀티 링크 디바이스는 제1 STA을 통해 TXOP의 절단(truncation)을 위한 제1 제어 프레임을 수신할 수 있다. 멀티 링크 디바이스는 제1 제어 프레임에 기초하여, 상기 제2 STA의 상태를 수면 상태에서 어웨이크 상태로 변경할 수 있다.
