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.

Abstract: The technology of this application relates to methods and apparatuses for sending and receiving a physical layer protocol data unit. The method includes generating a physical layer protocol data unit (PPDU), where the PPDU includes a short training field, a length of a frequency domain sequence of the short training field is greater than a first length, and the first length is a length, for example, 2048, of a frequency domain sequence of a short training field that is transmitted over a 160 MHz-bandwidth channel. The method further includes sending the PPDU over a target channel, where a bandwidth of the target channel is greater than 160 MHz. According to embodiments of this application, a larger actual channel bandwidth can be achieved, and backward compatibility is implemented.

Abstract: A non-AP MLD or a first STA in the non-AP MLD generates a first frame. The first frame includes indication information for indicating padding duration for a channel switch delay in an initial control frame. The padding duration is determined based on duration of a control response frame. The non-AP MLD or the first STA or another STA in the non-AP MLD transmits the first frame. An AP MLD or a first AP or another AP in the AP MLD receives the first frame. The AP MLD or the first AP determines the padding duration of the initial control frame based on the indication information.
