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: 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.

Abstract: Embodiments of this application disclose a method for determining a data buffer status, and an apparatus. The method includes: A first MLD receives first indication information from a second MLD, and determines, based on the first indication information and a correspondence between an association identifier of the first MLD and a data type supported by the first MLD, a buffer status of bufferable data that corresponds to the at least one data type and that is in the second MLD, where the first indication information is used to indicate the buffer status of the bufferable data. According to the embodiments of this application, a data buffer status in a data type dimension can be determined. The embodiments of this application may be applied to a wireless local area network system that supports a next-generation Wi-Fi EHT protocol of the IEEE 802.11, that is, the 802.11 protocol such as 802.11be.

Abstract: This application discloses a multi-link communication probe request method and apparatus. The method includes: a non-access point multi-link device (non-AP MLD) generates a probe request frame, and sends the probe request frame to an access point multi-link device (AP MLD), and the AP MLD receives the probe request frame, and generates a probe response frame and sends to the non-AP MLD. The probe request frame includes a first multi-link element (MLE) that is used to request link information of the AP MLD and that includes a first link information field. The first link information field includes a first field. The first field indicates that the non-AP MLD requests the AP MLD to feed back complete information or partial information of a first link. The first link information field corresponds to the first link.

Abstract: This application provides a method for transmitting a wake-up packet in a communications system and a device. The communications system includes a transmit end device and a receive end device. The receive end device includes a wake-up receiver and a main transceiver. The method includes: sending, by the transmit end device, a first wake-up packet WUP to the wake-up receiver by using a first data rate; determining, by the transmit end device, a second data rate; and sending, by the transmit end device, a second WUP to the wake-up receiver by using the second data rate. The transmit end device can determine a proper data rate for sending a wake-up packet based on a specific transmission condition in a communication process, thereby improving transmission efficiency of the wake-up packet.
