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.

Abstract: An antenna pattern selection method includes a first communication device sending a plurality of packets to a second communication device. Then, the first communication device measures, in each of a plurality of antenna patterns, signal quality of a plurality of acknowledgment frames with which the second communication device separately responds to the plurality of packets, and finally selects a dominant antenna pattern from the plurality of antenna patterns based on signal quality corresponding to each of the plurality of antenna patterns. According to the antenna pattern selection method, when normal communication is not affected, the first communication device may determine, based on signal quality of an acknowledgment frame, whether an antenna pattern used by the first communication device is proper.
