Abstract: A method for identifying a line of sight path and a wireless device are disclosed. In the method, an access point (AP) receives radio signals sent by a to-be-identified terminal through a plurality of paths, and obtains an energy of the radio signal transmitted through each of the paths. When a ratio of an energy of the radio signal transmitted through a candidate path to a total energy of the radio signals transmitted through the plurality of paths is greater than a threshold, the AP determines that the candidate path of the plurality of paths is a line of sight path.

Abstract: A transmit power control method is disclosed. An example method includes obtaining a path loss between a to-be-adjusted wireless device and each of multiple wireless devices. A transmit power of the to-be-adjusted wireless device is adjusted according to a neighbor path loss and a target power. The neighbor path loss is a function of a neighbor path loss set. The neighbor path loss set is a set of path losses of a neighbor wireless device set. The neighbor wireless device set is a set of at least two wireless devices among the multiple wireless devices, where path losses between the at least two wireless devices and the to-be-adjusted wireless device are lowest. A layer closest to the to-be-adjusted wireless device is used as a reference to adjust the transmit power, and interference between wireless devices is reduced.
