Abstract: An interference information detection method and a related apparatus are disclosed. The method includes: A server collects information about the plurality of frames from the plurality of stations, where information about some of the plurality of frames includes sending time, contention time, and frame duration, and the contention time indicates time at which a corresponding frame starts to wait to be sent or duration in which the corresponding frame waits to be sent; and the server determines the interference information about the plurality of stations based on the information about the plurality of frames.

Abstract: A method, an apparatus, and a system for setting up a direct link, and a method and an apparatus for sending a wireless local area network frame. The method includes: a first multi-link device sets up, based on parameters of a plurality of stations belonging to the first multi-link device and device information of a second multi-link device, at least one direct link between the first multi-link device and the second multi-link device. Each of the at least one direct link is connected to one of the plurality of stations belonging to the first multi-link device and one station belonging to the second multi-link device.

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.
