Abstract: A method for selecting a cyclic shift diversity sequence, and a related apparatus are disclosed. The method includes: sending a frame by using a cyclic shift diversity (CSD) sequence, comprising: generating a frame, wherein the frame comprises a first data subframe conforming to a first communication mechanism and a third data subframe conforming to the first communication mechanism; sending the frame, wherein the first data subframe and the third data subframe are sent by using a cyclic shift diversity sequence. Under an EHT standard, a preferred cyclic shift diversity sequence can be obtained through selection from massive combinations of CSD values. Work efficiency is improved, and an operation burden is reduced.

Abstract: Embodiments of this application provide an access point (AP) multi-link device discovery method and a related apparatus, for example, in a wireless local area network (WLAN) supporting IEEE 802.11be. In an example method, a reporting AP sends a first management frame to a station. The first management frame carries information about a reported AP. The reporting AP is affiliated with an AP multi-link device. The reported AP is affiliated with the same multi-link device as the reporting AP. Or the reported AP belongs to a same multiple basic service set identifier (BSSID) set as another AP in the multi-link device with which the reporting AP is affiliated.

Abstract: Provided are a spatial reuse method, an apparatus, a device, and a medium. In the method, a first spatial reuse device receives a portion or all of a PSRR PPDU sent by a second spatial reuse device on a first frequency band. The first frequency band includes one or more subbands with a same bandwidth. The first spatial reuse device determines, based on a value of a spatial reuse parameter SRP at a granularity of the bandwidth and a received power level RPL of the PSRR PPDU at a granularity of the bandwidth, a reference transmit power for sending a PSRT PPDU on a second frequency band. The second frequency band includes one or more subbands with the bandwidth. The second frequency band and the first frequency band at least partially overlap.

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.
