Abstract
Embodiments of this application provide a channel sounding method and apparatus, and relate to the communication field. The method includes: A station STA receives channel sounding frames sent by a plurality of access points APs; the STA performs channel sounding based on the channel sounding frames to obtain channel state information of each AP; and the STA sends a channel measurement report frame, where the channel measurement report frame includes channel state information of some of the plurality of APs and identifiers of the some APs, and the channel measurement report frame is further used to indicate that the some APs are selected to participate in coordinated transmission. That the channel measurement report frame is used to indicate that an AP is selected to participate in coordinated transmission can not only feedback channel state information but also reduce signaling overheads.
