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.
