Abstract: This application provides a beam information obtaining method and an apparatus, relates to the field of communications technologies, and resolves a problem that resources of positioning reference signals are wasted because the positioning reference signals need to be omnidirectionally sent because of an unknown direction, of a terminal, caused by use of a beam, when the terminal is positioned in, e.g., a 5G system. The method in this application resolves the problem and saves overheads of sending a reference signal. The method includes: The terminal receives a beam information request sent by a location management device, where the beam information request is used to request the terminal to provide measurement information of a downlink beam. The terminal obtains beam information, where the beam information includes information about a reference signal that is sent by at least one network device and that is measured by the terminal.

Abstract: This application provides a positioning method and a communication apparatus. When reporting, to a network device, measurement information of a plurality of paths that is obtained through positioning measurement, a terminal device associates each path with a positioning reference signal PRS resource identifier or related information of a beam (for example, an angle of a transmit beam or a direction of the transmit beam) corresponding to the PRS resource identifier. While learning of the measurement information of each path, the network device can further learn of information about a beam corresponding to the path. This helps the network device improve positioning accuracy.

Abstract: This application provides a positioning reference signal sending method and a related apparatus. The method includes: receiving identification information, positioning reference signal (PRS) indication information, and PRS identification information of a terminal device from a location management function network element; sending the PRS identification information to the terminal device; and sending a first PRS to the terminal device. Based on the foregoing technical solutions, the terminal device may receive a PRS of another type other than a periodic PRS. Therefore, more PRSs are used for location measurement. In this way, positioning precision can be improved.
