Abstract: A sensing result feedback method, an apparatus, a device, and a medium are provided. In an example method, a sensing initiating device sends an indication about truncation and feedback of a time domain channel estimation and sensing sequence to a first sensing responding device. The first sensing responding device truncates the received time domain channel estimation and sensing sequence based on the indication, and feeds back the truncated time domain channel estimation and sensing sequence. Therefore, a sensing sender may perform channel estimation and target sensing based on the truncated time domain channel estimation and sensing sequence. In this manner, feedback overheads can be significantly reduced, and sensing performance can be ensured to some extent.

Abstract: The present disclosure relates to feedback methods and apparatuses. In one example method, a first communication apparatus may receive first information. The first information includes at least one of channel state information (CSI) measurement quantity indication information 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, whether to trigger the second communication apparatus/apparatuses to send a feedback result. Correspondingly, the first communication apparatus receives the feedback result.

In an example method includes, a first access point (AP) in a first access point multi-link device (AP MLD) generates and sends a first frame. The first frame indicates critical BSS parameter update count values corresponding to a plurality of APs in the first AP MLD and critical BSS parameter update count values corresponding to a plurality of APs in a second AP MLD. The second AP MLD is an AP MLD to which a nontransmitted AP belongs. The nontransmitted AP is in a multiple basic service set identifier (BSSID) set including the first AP.
