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: An association establishment method and apparatus, for carrying out the method are described. The association establishment method includes



broadcasting, by an access point (AP), a trigger frame, wherein the trigger frame is used to trigger one or more unassociated stations STAs to perform uplink data transmission and indicate one or more available subchannels for random accessing of the unassociated STAs. The method further includes receiving, by the AP, one or more association request messages sent on available subchannels acquired by the unassociated STAs. Thereafter, the AP broadcasts a multi-block acknowledgement M-BA frame, wherein the M-BA frame includes one or more pieces of association acknowledgement information and the association acknowledgement information is acknowledgement information of the association request message.

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).
