    Abstract: This application provides a bandwidth indication method applied in a wireless local area network supporting the 802.11be standard and a communication apparatus. The method includes: An access point generates a physical layer protocol data unit PPDU, where a transmission bandwidth of the PPDU is divided into a plurality of segments, the PPDU includes a universal signal U-SIG field carried on a segment, the U-SIG field includes a bandwidth field, and the bandwidth field indicates a channel bandwidth of a resource unit allocated to a station parked in the segment; and the access point sends the PPDU to the station. The method in this application can be used to reduce signaling overheads of PPDU transmission, and resources across segments can be allocated to the station, so that resources can be more flexibly allocated.

    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.
