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.

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.
