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: Embodiments of this application disclose a communication method between multi-link devices and an apparatus, and relate to the field of communications technologies, to reduce power consumption of a station multi-link device. A specific solution is as follows: A multi-link device includes a plurality of STAs, one STA operates on one of a plurality of links, and the STA determines a primary link in the plurality of links. A STA operating on the primary link in the multi-link device may receive information sent by the AP indicating whether the STA operating on the primary link has a downlink traffic, and/or information indicating whether a STA operating on a link other than the primary link has a downlink traffic. Therefore, the STA operating on the primary link may determine a link on which the STA having a downlink traffic operates in the multi-link device.

Abstract: This application provides a beacon frame transmission control method and a related apparatus. The method includes: generating, by a master access point AP, indication information used to indicate a transmission time period of a beacon frame of at least one secondary AP; and sending, by the master AP, the indication information to the at least one secondary AP, where the master AP and the at least one secondary AP belong to a same AP collaboration group, and transmission time periods of beacon frames of APs in the AP collaboration group are different. According to technical solutions provided in this application, transmission robustness of the beacon frame can be improved.

Abstract: Embodiments of this application disclose a spatial reuse indication method and a wireless communications apparatus, thereby reducing a quantity of nodes that can participate in spatial reuse, reducing mutual interference between nodes in spatial reuse, and improving spatial reuse system performance. The method in some implementations includes a first access point generates a spatial reuse limitation indication and a spatial reuse group indication. The spatial reuse limitation indication can be used to indicate whether only a node in a spatial reuse group is allowed for spatial reuse and to indicate the spatial reuse group. The spatial reuse group includes one or more basic service sets. The first access point sends the spatial reuse limitation indication and the spatial reuse group indication.

Abstract: A method includes: A first device sends a block acknowledgment request frame to a second device. The block acknowledgment request frame is used to request the second device to send a block acknowledgment frame. The block acknowledgment frame indicates a receiving status of an access control layer protocol data unit in first transmission. The first transmission is suspended at a first moment, and the first moment is earlier than a transmission end moment when the first transmission is not suspended. The first device receives the block acknowledgment frame. The first device starts, at a second moment, to perform second transmission.

Abstract: This application relates to the field of wireless communication, and in particular, to an orthogonal frequency division multiple access (OFDMA) hybrid transmission method and apparatus. The method includes: An access point may send a trigger frame, to schedule stations supporting different standards to perform OFDMA uplink transmission, where the stations supporting different standards support different bandwidth sizes. The stations receiving the trigger frame send a trigger-based physical layer protocol data unit (TB PPDU) to the access point, where the TB PPDU includes uplink data of the stations supporting different standards, and the stations of different standards may send the uplink data by using RUs located in bandwidths respectively supported by the stations. Therefore, a channel can be fully utilized to improve frequency domain resource utilization.
