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: This application provides a resource allocation method, a communication apparatus, and a computer-readable storage medium. An access point determines and sends a band indication and a resource unit allocation indication based on an RU/MRU allocated to a PPDU. The band indication indicates an index of a band of the RU/MRU, and an index range corresponding to the band indication in a first bandwidth is reused for an index range corresponding to the RU/MRU in a bandwidth of the PPDU. The resource unit allocation indication indicates an RU/MRU index of the RU/MRU on the band, and an index range corresponding to the resource unit allocation indication in the first bandwidth is also reused for an index range corresponding to the resource unit allocation indication in the bandwidth of the PPDU. The first bandwidth is greater than the bandwidth of the PPDU.

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.

Abstract: Embodiments of this application provide an access point (AP) multi-link device discovery method and a related apparatus, for example, in a wireless local area network (WLAN) supporting IEEE 802. 1 1be. In an example method, a reporting AP sends a first management frame to a station. The first management frame carries information about a reported AP. The reporting AP is affiliated with an AP multi-link device. The reported AP is affiliated with the same multi-link device as the reporting AP. Or the reported AP belongs to a same multiple basic service set identifier (BSSID) set as another AP in the multi-link device with which the reporting AP is affiliated.
