Abstract: 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.

Abstract: Example methods and apparatus for indicating downlink service data are described. One example method includes sending, by a first station (STA), a request frame to a wireless access point (AP). The request frame includes listen interval information, the listen interval information includes duration of a first listen interval, and the first STA is equipped with main radio and a wake-up receiver. The first STA receives a response frame sent by the AP, where the response frame carries an identity allocated by the AP to the first STA, and the identity of the first STA comprises an identity of the wake-up receiver of the first STA. The first STA controls the wake-up receiver to wake up within the first listen interval, and receives a wake-up beacon frame periodically sent by the AP.

Abstract: This application relates to the field of wireless communication, and in particular, to an orthogonal frequency division multiple access (OFDMA) hybrid transmission method and apparatus. The method includes: An access point may send a trigger frame, to schedule stations supporting different standards to perform OFDMA uplink transmission, where the stations supporting different standards support different bandwidth sizes. The stations receiving the trigger frame send a trigger-based physical layer protocol data unit (TB PPDU) to the access point, where the TB PPDU includes uplink data of the stations supporting different standards, and the stations of different standards may send the uplink data by using RUs located in bandwidths respectively supported by the stations. Therefore, a channel can be fully utilized to improve frequency domain resource utilization.

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 comprises 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.
