Abstract: Embodiments of this application disclose a communication method, to optimize a channel access parameter. The method includes: A first station sends a request frame to an access point. The request frame is used to request to obtain a channel priority access right. The request frame carries a first parameter set. The first parameter set includes MU EDCA parameters that the first station intends to use to perform channel contention. The first station receives a response frame for the request frame. The first station is an EPCS station. The first station performs channel access by using an MU EDCA mechanism. In embodiments of this application, the first parameter set includes the MU EDCA parameters that the first station intends to use to perform channel contention. The request frame carrying the first parameter set is sent. In this way, channel contention is performed by using parameters with a higher channel access priority.

Abstract: This application discloses a multi-link communication method and apparatus. The method includes: A transmitter sends a first A-MPDU, and a receiver receives the first A-MPDU. The receiver obtains a locally recorded scoreboard context, and when the first A-MPDU meets at least one of the following conditions: a first condition, a second condition, a third condition, or a fourth condition, the receiver refreshes the scoreboard context based on an SN of the first A-MPDU. According to the method provided in this application, the receiver can properly and effectively refresh the local scoreboard context, to ensure that the receiver correctly feeds back receiving statuses of all MPDUs in an A-MPDU received by the receiver.

Abstract: The present disclosure relates to communication methods and apparatuses. In one example method, a non-access point multi-link device (non-AP MLD) receives a first frame from a first access point (AP) when performing a listening operation on a first link. The non-AP MLD switches some or all of spatial streams/antennas on each link of the non-AP MLD to the first link to perform a frame exchange with the first AP. When determining that any preset condition in a preset condition set is met, the non-AP MLD switches some spatial streams/antennas on the first link back to each link or another link to perform the listening operation.

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.
