Abstract: Example communication methods and apparatus are described. One example method includes sending one or more configuration indications by a first station. One configuration indication in the one or more configuration indications corresponds to one second station in one or more second stations. The configuration indication includes an identifier of the second station and a transmit beam indication, and the transmit beam indication is used to indicate a transmit beam used by the second station to send data. The second station receiving the configuration indication sends the data to the first station through the transmit beam indicated by the transmit beam indication. According to the embodiments of this application, the first station can control the second station to perform data transmission.

Abstract: This application provides a data communications method and apparatus. The method includes: A first STA receives time adjustment information, where the time adjustment information is used to indicate a sending moment at which a signal is sent by using each of at least two beams. The first STA may send data at a corresponding sending moment based on the time adjustment information by using a corresponding beam. In this way, an AP can simultaneously receive data sent by at least one station by using the at least two beams. This ensures data validity and improves data communication efficiency.

Abstract: This application provides a data transmission method. When performing data transmission with a first station in a bandwidth power saving mode by using an operating channel of the first station, an access point performs data transmission with a second station by using an operating channel of the second station. Therefore, even if the operating channel of the first station includes a primary channel, the access point can still perform data transmission with the second station by using another channel. Further, for the access point, although the operating channel of the first station occupies only a part of available bandwidth resources of the access point, the access point can still perform data transmission with the second station by using a remaining channel.
