The method includes: 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 DMRS sending method, a DMRS receiving method, and a communication apparatus. The method includes: receiving indication information indicating a scheduled DMRS port; and sending a DMRS on the scheduled DMRS port. The scheduled DMRS port belongs to a DMRS port set, the DMRS port set includes M DMRS ports, the M DMRS ports correspond to a first time domain position and a second time domain position, and a first DMRS port set corresponding to the first time domain position is different from a second DMRS port set corresponding to the second time domain position. In this way, different DMRS port sets are mapped to the first time domain position and the second time domain position, so that more orthogonal DMRS ports can be supported, thereby improving a system capacity.

Abstract: This application provides a protocol data unit PPDU transmission method and apparatus, and relates to the field of communication technologies, to indicate, to a STA, a channel for sending a CTS frame. In the method, a first device may send a first data unit. The first data unit may include at least a second data unit and a third data unit. The second data unit is used to carry a first MU-RTS frame. The third data unit is used to carry a second MU-RTS frame. The first MU-RTS frame and the second MU-RTS frame use a same scrambling code initialization value. Based on the foregoing solution, an AP may indicate, to a plurality of STAs by using a plurality of MU-RTS frames, channels for replying CTS frames. The AP may indicate the first MU-RTS frame and the second MU-RTS frame to use the same scrambling code initialization value.

Abstract: In a power control method in a wireless local area network, a beamformer sends a null data packet (NDP) via a plurality of spatial streams to beamformees. After receiving the NDP, a beamformee determines a first parameter for power control based on RSSIs of a plurality of receive antennas when the beamformee receives the NDP, or based on SNRs of a plurality of spatial streams when the beamformee receives the NDP. The beamformee then generates a beamforming report comprising the first parameter, and sends the beamforming report to the beamformer.
