Abstract: In a channel listening method, a non-simultaneous transmit and receive multi-link device (NSTR MLD) receives a first response frame on a first link and a second response frame on a second link, wherein an end time of the first response frame is later than an end time of the second response frame, and the first link and the second link belong to a NSTR link pair. The NSTR MLD determines that at least one of the first response frame and the second response frame fails to be received. In response to the determination, the NSTR MLD performs channel listening in a first interframe space after the first response frame ends, wherein a duration of the first interframe space is less than or equal to a duration of a point coordination function interframe space (PIFS).

Abstract: This application discloses a multi-link establishment method and a related device. A multi-link association response frame carries radio bitmap information, to indicate an AP allowed to be associated with a radio of a STA MLD or a link allowed to be established by using a radio of a STA MLD, so that the radio subsequently switches between different APs or links. The multi-link association response frame carries link establishment status information, to indicate a link establishment status of each link that the STA MLD requests to establish, so that multi-link establishment is more flexible. The multi-link association response frame carries reassociation information, to indicate whether each parameter in association configuration information is reserved, so that a problem that signaling overheads are relatively large due to a reassociation operation is avoided. It can be learned that, in the multi-link establishment method, the foregoing information is carried to improve multi-link establishment flexibility.

Abstract: This application provides a spatial reuse method and apparatus based on multi-access point (AP) coordination, and a system. In the method, a first access point AP sends a radio frame including identification information to a second access point AP. The identification information is used to indicate the second access point AP to perform spatial reuse during uplink data transmission performed by at least one first station associated with the first access point. The second access point sends a downlink frame to at least one second station based on the identification information. Through coordination between access points APs, the first AP may configure a spatial reuse transmission opportunity for another specific AP to perform spatial reuse transmission, so that a transmission time in the spatial reuse transmission opportunity is fully used, thereby avoiding a conflict and improving transmission efficiency.
