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 disclosure provides a communication method and a communication apparatus. In some aspects, a network device receives first indication information from a core network device, where the first indication information indicates the network device to trigger, after receiving uplink data from a first terminal device, a second terminal device to access the network device. After the network device receives first uplink data from the first terminal device, the network device triggers the second terminal device to access the network device. According to the method, complexity of data transmission and processing procedures of an inventory taking procedure transplanted to a cellular network can be reduced, so that an inventory taking rate of terminal devices and a communication capacity of a system are effectively improved.
