摘要： This application relates to the field of wireless communication, and is applied to a wireless local area network that supports the 802.11 series standards such as the 802.11bf standard, and in particular, to a measurement setup identifier determining method and a related apparatus. The method includes: A requesting STA requests an AP as a proxy of the requesting STA to perform sensing measurement. The AP obtains parameters used by the AP and a sensing responder (STA 3) in a proxy sensing procedure, and identifies the parameters. The AP uses an identifier different from an existing identifier at the AP when identifying the parameters. The AP then sends the parameters and the identifier to the sensing responder (STA 3). According to embodiments of this application, a problem of setting a measurement setup identifier in a proxy sensing scenario can be resolved, so that the measurement setup identifier set in the proxy sensing scenario can be distinguished from a measurement setup identifier set in a non-proxy sensing scenario.

The first information includes at least one of the following types of information: CSI measurement quantity indication information required for channel variation calculation, a CSI type and a rule that are for the channel variation calculation, or a feedback suggestion parameter. The feedback suggestion parameter indicates a suggested feedback form. The first information is used to select a second communication apparatus. The first communication apparatus may determine, based on the first information, a second communication apparatus/second communication apparatuses to be triggered, and send a second PPDU, to trigger the second communication apparatus/apparatuses to send a feedback result. Correspondingly, the first communication apparatus receives the feedback result. This application is applied to a wireless local area network system supporting IEEE 802.11ax next-generation Wi-Fi protocols, for example, 802.11 series protocols such as the 802.11be or the EHT.
