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 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: 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.
