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.
