Abstract: This application provides a channel sounding method and apparatus. The method includes: A first communication device sends a first frame to a second communication device, where the first frame is used to indicate the second communication device to perform channel sounding on a part of antennas of the first communication device. The first communication device sends a second frame to the second communication device, where the second frame is used by the second communication device to perform channel sounding on the part of antennas. The first communication device receives a third frame from the second communication device, where the third frame is used to indicate a result of performing channel sounding on the part of antennas.

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: A communication method and apparatus are provided, which relate to the field of communication technologies, to determine an interaction procedure in an ATI in an AP coordination scenario. The method includes: A C-AP generates a first indication frame, where the first indication frame indicates an interaction procedure between an M-AP, the C-AP, and a STA in the ATI; and the C-AP sends the first indication frame to a plurality of M-APs, so that the plurality of M-APs perform the interaction procedure in the ATI based on the first indication frame.

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 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.
