Abstract: A communication method includes a first communication device that sends, to a second communication device, a physical layer protocol data unit (PPDU) including indication information and M link adaptation blocks, where the indication information indicates a resource used for link adaptation, the M link adaptation blocks use different transmission parameters, and the resource is used to transmit the M link adaptation blocks. The second communication device returns, to the first communication device, a feedback result determined based on a measurement result corresponding to the M link adaptation blocks, so that the first communication device sends, based on the feedback result, a PPDU used for data transmission. Hence, the two communication devices complete link adaptation through one interaction, and do not need to perform a plurality of interactions.

Abstract: Embodiments of this application relates to a multi-link communication setup method and a related apparatus. The method includes: a non-AP MLD sends an association request frame on a first link, to request multi-link setup. An AP MLD returns an association response frame on the first link, to notify whether multi-link setup succeeds. The AP MLD sets a second status code field of a multi-link element of the association response frame to a newly defined value, to indicate that a cause why a link is not accepted is that the first link is not accepted. This application is applied to a WLAN system that supports a next generation Wi-Fi protocol of 802.11ax, for example, 802.11be, Wi-Fi 7, or EHT, and other 802.11 series protocols; and for another example, a next generation protocol of 802.11be: Wi-Fi 8.

Abstract: An AID allocation method for a multi-link device, includes: An access point multi-link device generates and sends a first frame. Correspondingly, a station device receives and parses the first frame to obtain an AID that is allocated to the station device and carried in the first frame. The AID is neither a BSSID that can be supported by a first-type access point in the access point multi-link device nor an identifier of an access point in the access point multi-link device. The first-type access point is an access point for establishing a link between the station device and the access point multi-link device.
