Abstract
(EN)
In a wireless local area network (LAN) system, a first station (STA) may check the transfer failure of a first acknowledgement (ACK) signal for a first frame, the signal being received through a first link. The first STA may transmit report information related to the transfer failure of the first ACK signal to a second STA through a second link. Here, the report information may include identification information associated with the first link. The first STA may receive a second frame from the second STA through the first link. The first STA may transmit a second ACK signal for the second frame to the second STA through the first link on a narrowband.
(FR)
La présente invention concerne une première station (STA), dans un système de réseau local sans fil (LAN), pouvant vérifier la défaillance de transfert d'un premier signal d'accusé de réception (ACK) destiné à une première trame, le signal étant reçu par l'intermédiaire d'une première liaison. La première STA peut émettre des informations de rapport relatives à la défaillance de transfert du premier signal ACK à une seconde STA par l'intermédiaire d'une seconde liaison. Les informations de rapport peuvent comprendre des informations d'identification associées à la première liaison. La première STA peut recevoir une seconde trame de la seconde STA par l'intermédiaire de la première liaison. La première STA peut émettre un second signal ACK destiné à la seconde trame à la seconde STA par l'intermédiaire de la première liaison sur une bande étroite.

무선랜(Wireless Local Area Network) 시스템에서, 제1 STA(station)은 제1 링크를 통해 수신된 제1 프레임을 위한 제1 ACK(acknowledgement) 신호의 전달 실패를 확인할 수 있다. 상기 제1 STA은 제2 STA에게 상기 제1 ACK 신호의 전달 실패에 관련된 보고 정보를 제2 링크를 통해 송신할 수 있다. 여기서, 상기 보고 정보는 상기 제1 링크에 관련된 식별 정보를 포함할 수 있다. 상기 제1 STA은 상기 제2 STA으로부터 제2 프레임을 상기 제1 링크를 통해 수신할 수 있다. 상기 제1 STA은 상기 제2 STA에게 상기 제2 프레임을 위한 제2 ACK 신호를 상기 제1 링크를 통해 협대역(narrowband)으로 송신할 수 있다.
