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.

Abstract: This application relates to the field of wireless communication, and in particular, to individually addressed traffic indication methods and apparatuses applicable to multiple links, for example, in a wireless local area network supporting an 802.11be standard. In an example method, a first access point (AP) of a first access point multi-link device (AP MLD) generates and sends individually addressed traffic indication information. The individually addressed traffic indication information is used to indicate whether a non-AP MLD associated with the first AP MLD has a downlink individually addressed traffic and whether a non-AP MLD associated with a second AP MLD has a downlink individually addressed traffic. The second AP MLD is an AP MLD to which a non-transmitted AP belongs. The non-transmitted AP is in a multiple basic service set identifier (BSSID) set in which the first AP is located.

Abstract: The present disclosure relates to communication methods and apparatuses, and relates to the field of communication technologies. In one example method, a first communication apparatus generates a physical layer protocol data unit (PPDU), and sends the PPDU to a second communication apparatus. The PPDU includes a first field with 26 bits, and the first field includes a one-bit unsolicited modulation and coding scheme (MCS) feedback (MFB) subfield and a one-bit first indication information. When a value of the unsolicited MFB subfield is a first value, the first indication information indicates an MCS request (MRQ). When a value of the unsolicited MFB subfield is a second value, the first indication information indicates an uplink extremely high throughput trigger-based PPDU MFB (UL EHT TB PPDU MFB).

Abstract: This application discloses a communication method and apparatus. The method includes: transmitting, by a second station in a second multi-link device, a first frame to a first station in a first multi-link device, where the first frame is used to request to tear down a TWT agreement for a first link, and the first link is any link in one or more links for which a TWT agreement is set up between the first multi-link device and the second multi-link device; and transmitting, by the first station, a second frame to the second station in response to the first frame. The first station may be any station, and is not limited to a station requesting to set up the TWT agreement.

Abstract: Provided are a method for performing feedback based on channel state information (CSI), a device, and a medium. In an example method, a sensing response device obtains CSI data based on channel estimation, and generates power delay profile (PDP) data based on the CSI data. Then, the sensing response device feeds back a part of PDP data in the generated PDP data. Therefore, feedback overheads are reduced. In addition, sensing performance is ensured to some extent.

Abstract: The embodiments of this application provides a cyclic shift diversity sequence-based communication method. In the method, a first communication apparatus generates a physical layer protocol data unit (PPDU) and sends the PPDU to a second communication apparatus. The PPDU includes a short training field (STF), a long training field (LTF), and a data field that are determined based on a cyclic shift diversity (CSD) sequence. After receiving the PPDU from the first communication apparatus, the second communication apparatus performs processing based on the PPDU. The CSD sequence includes L elements. L is a maximum number of spatial streams supported by the first communication apparatus and the second communication apparatus. The maximum number of spatial streams is greater than or equal to 16.

The method includes generating a PPDU, where the PPDU includes an extremely high throughput-long training field (EHT-LTF). The EHT-LTF is obtained based on a P matrix and a predefined EHT-LTF sequence. The P matrix is an n×n orthogonal matrix, n is an integer greater than 8, and a first row of the P matrix includes at least one element whose value is 1 and at least one element whose value is −1. The method further includes sending the PPDU. This application may be applied to a wireless local area network (WLAN) system supporting a next-generation wireless fidelity (Wi-Fi) extremely high throughput (EHT) protocol of IEEE 802.11, for example, 802.11 protocols such as 802.11be.

Abstract: This application provides example object locating methods and apparatuses. One example method includes performing, by a first device, pulse measurement on a target object with assistance of a second device, where the pulse measurement is performed on the target object by using two types of pulse signals, and pulse repetition frequencies of the two types of pulse signals are different. The first device can then locate the target object based on a pulse measurement result of the pulse measurement.
