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: APPDU-based communication method and apparatus are disclosed, are used in a wireless local area network system that supports 802.11 series protocols such as a next-generation Wi-Fi protocol of IEEE 802.11ax, for example, 802.11be, Wi-Fi 7, or EHT, and a next-generation protocol of 802.11be, for example, Wi-Fi 8. A transmit end generates a PPDU, and sends the PPDU on a first high frequency channel. Correspondingly, a receive end receives the PPDU on the first high frequency channel, and processes the PPDU. The first high frequency channel may include a first pilot subcarrier and a first data subcarrier, a quantity of first pilot subcarriers is greater than a quantity of second pilot subcarriers, and a quantity of first data subcarriers is equal to a quantity of second data subcarriers. This can effectively improve demodulation accuracy of the receive end.

Abstract: A communication method includes an access point (AP) multi-link device (MLD) that generates first signaling via an affiliated AP affiliated to the AP MLD, where the first signaling indicates a mapping relationship between a traffic identifier and a link, and the mapping relationship indicated by the first signaling periodically takes effect; and the AP MLD sends, via the affiliated AP, the first signaling to a non-AP MLD associated with the AP MLD. The mapping relationship indicated by the sent first signaling periodically takes effect.

Abstract: An access point receives restricted target wake time setup request information sent by a station. The restricted target wake time setup request information is used to request to set up a restricted target wake time. The access point sends restricted target wake time response information to the station. The restricted target wake time response information is used to respond to the restricted target wake time setup request information. The restricted target wake time setup request information or the restricted target wake time response information includes indication information of a first access category corresponding to low-latency traffic of the station. The station or the access point can independently and selectively configure the access category for the low-latency traffic.
