The method includes: a multi-link device includes a plurality of STAs, one STA operates on one of a plurality of links, and the STA determines a primary link in the plurality of links. A STA operating on the primary link in the multi-link device may receive information sent by the AP indicating whether the STA operating on the primary link has a downlink traffic, and/or information indicating whether a STA operating on a link other than the primary link has a downlink traffic. Therefore, the STA operating on the primary link may determine a link on which the STA having a downlink traffic operates in the multi-link device.

Data transmission method and apparatus

A ML entity performs a backoff procedure of the primary link based on the backoff counter of the primary link; and when a count value of the backoff counter is 0, the ML entity sends a first PPDU on each first link in K first links, where the K first links include the primary link and K−1 first nonprimary links, and the first nonprimary link is in an idle state in a first inter-frame space before a time point at which the count value of the backoff counter decreases to 0.

Communication method and apparatus

This application provides data transmission methods and apparatuses, to introduce a buffer status report (BSR) mechanism through multi-link (ML) cooperation, to improve performance of scheduling a station by an ML device. In an example method, a multi-link transmit end determines BSR signaling sent to a multi-link receive end, where the BSR signaling can enable the multi-link receive end to schedule a station of the multi-link transmit end over one or more links. Further, the multi-link transmit end sends the B SR signaling to the multi-link transmit end over the one or more links. This introduces a BSR mechanism through ML cooperation.

Flexible scheduling of a slave AP in a unified frame format in a multi-AP coordinated transmission scenario provides an information transmission method. A first access point (AP) generates a slave trigger frame, where the slave trigger frame includes trigger type information and AP indication information. The trigger type information is used to indicate a type of the slave trigger frame. The AP indication information includes an identifier of a second AP. The identifier of the second AP is used to indicate the second AP. The slave trigger frame is used to trigger the second AP to send a physical protocol data unit (PPDU). The PPDU carries a frame corresponding to a type of the slave trigger frame. The first AP sends the slave trigger frame to the second AP.

This application relates to the wireless communication field, and in particular, to critical basic service set (BSS) parameter management method applicable to multiple links and a related apparatus that are applied to, for example, a wireless local area network supporting the 802.11be standard. A first access point (AP) in a first access point multi-link device (AP MLD) generates and sends a first frame, where the first frame indicates critical BSS parameter update count values corresponding to a plurality of APs in the first AP MLD and critical BSS parameter update count values corresponding to a plurality of APs in a second AP MLD, and the second AP MLD is an AP MLD to which a nontransmitted AP belongs in a multiple basic service set identifier (BSSID) set including the first AP.

This application discloses methods and apparatuses applicable to multiple links, for example, in a wireless local area network supporting an 802.11be standard. In an example, a first station (STA) of a first non-access-point multi-link device (non-AP MLD) receives individually addressed traffic indication information that indicates whether the first non-AP MLD associated with a first access point multi-link device (AP MLD) has a downlink individually addressed traffic and whether a second non-AP MLD associated with a second AP MLD has a downlink individually addressed traffic. The second AP MLD is an AP MLD to which a non-transmitted AP belongs, and the non-transmitted AP is in a multiple basic service set identifier (BSSID) set in which the first AP is located. The first STA determines whether the first non-AP MLD has a downlink individually addressed traffic according to the individually addressed traffic indication information.
