Abstract: This application discloses channel sounding methods and communication apparatuses. One method includes: receiving, by a second access point, a user association frame from a first access point, wherein the user association frame carries identification information of a first station and is used to determine a first channel sounding result of the first station associated with the first access point, and determining, by the second access point, the first channel sounding result from a plurality of second channel sounding results based on the user association frame, wherein the plurality of second channel sounding results are obtained by the second access point by performing sounding on a plurality of channel sounding frames from a plurality of stations.

Abstract: A communications system is disclosed. The communications system includes a first access point and a second access point whose operating channels overlap. The first access point and the second access point each measure a signal strength of a response frame sent by a terminal device associated with the first access point, to obtain a first signal strength and a second signal strength. The first access point determines, based on the first signal strength and the second signal strength, a power, a power upper limit, or a power adjustment value to be used by the second access point when the second access point and the first access point perform concurrent transmission. The communications system can perform a step of measuring the signal strength in the concurrent transmission between the access points, and reduce dependence on the terminal device.
