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.

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.

Abstract: Embodiments of this application provide a service data transmission method, an access point, and a station. The method includes: receiving, by a station, a control frame, where the control frame includes control information; contending for a resource based on the control information; and sending first-type service data of the station to an access point on the resource obtained by contention, where the control information is used to instruct the station to contend for the resource used to transmit the first-type service data. In the embodiments of this application, the access point triggers the station to perform a procedure of reporting uplink first-type service data, and this can improve transmission efficiency of service data.
