Abstract: A positioning method and apparatus. A location management network element sends first indication information to a network device, where the first indication information is useable by the network device to measure a signal that is sent by a terminal device and that is reflected by a reflection panel. After receiving the first indication information, the network device measures the signal reflected by the reflection panel, and reports a measurement result to the location management network element. The location management network element determines a location of the terminal device based on location information of the network device, location information of the reflection panel, and the measurement result. In response to a line-of-sight (LOS) path between the terminal device and the network device being blocked, a signal on the LOS path cannot be directly transmitted and measured.
