摘要: Embodiments of this application provide a multistation coordination-based data transmission method and apparatus. The method includes: receiving, by a station, second data of another station, different from the station, in a coordination group to which the station belongs; sending, by the station, first data to the other station, so that the other station generates a second aggregated frame that includes the first data and the second data; and sending, by the station, a first aggregated frame to an access point. The first aggregated frame includes the first data and the second data. This reduces a transmit power of a single station, and prolongs a service lifespan of the station.

摘要: Embodiments of this application describe a communication method, a first station (STA), a second STA, and an access point (AP). The method includes: determining, by a first STA, a first basic service set (BSS) color; generating, by the first STA, a data frame when the first station STA and a second STA perform D2D transmission, where the data frame includes the first BSS color; and sending, by the first STA, the data frame to the second STA. The first BSS color is carried in the D2D data frame, so that when receiving the data frame, another receiving station in a BSS to which the first STA and the second STA belong can determine that the frame is a frame from a neighboring cell.

摘要: 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.
