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.

Abstract: Example methods for reporting user equipment location information and apparatus are described. In one example method, user equipment receives a first message, where the first message comprises a paging trigger indication, and the paging trigger indication is used to trigger the user equipment to report, when receiving a paging message, a measurement result of a positioning reference signal. The user equipment receives the paging message in an idle state or an inactive state. The measurement result of the positioning reference signal is reported by the user equipment based on the paging message.
