Abstract: A positioning information reporting method and an apparatus reduces a measurement error in a positioning technology and improves positioning precision. The method includes: a terminal device obtains request location information that is of a location management network element and that includes angle assistance information. The angle assistance information may indicate an angle between an access network element and the terminal device. The terminal device sends, to the location management network element, provide location information including a measurement result and first indication information corresponding to the measurement result. The measurement result may be a result of measuring, by the terminal device based on the angle assistance information, a signal sent by the access network element. The first indication information may indicate whether an angle corresponding to the measurement result is within the angle indicated by the angle assistance information.

Abstract: An uplink positioning method and a communication apparatus are provided, to reduce power consumption of a terminal in a positioning process, and meet a requirement for low power consumption. The method includes: A terminal receives first indication information and a first message, and sends, in a positioning area indicated by the first indication information, a reference signal based on resource configuration information corresponding to the positioning area. The first indication information indicates one or more positioning areas, the first message includes one or more pieces of resource configuration information, one piece of resource configuration information corresponds to one positioning area, each piece of resource configuration information is used to configure a resource for the terminal to send the reference signal, and the reference signal is used to determine a location of the terminal.

Abstract: This application provides a signal transmission method and apparatus, to help a terminal device determine a receive beam for a positioning reference signal. This can reduce overheads of performing receive beam sweeping by the terminal device, and save resources. The method includes: A terminal device receives a first positioning reference signal PRS resource set and a second PRS resource set that are sent by a network device, and learns that N first PRS resources in the first PRS resource set and N second PRS resources in the second PRS resource set satisfy a quasi-colocation QCL relationship.

Abstract: This application provides example signal transmission methods and example apparatuses. One example method includes receiving random access channel (RACH) configuration information of a neighboring cell from a location management device or a serving cell, where the RACH configuration information includes information about an RACH resource and a preamble. The preamble can then be sent to the neighboring cell by using the RACH resource. An uplink TA of the neighboring cell that is determined by the neighboring cell based on the preamble can then be received.

Abstract: This application provides a signal transmission method and apparatus. The method includes: A neighboring cell sends downlink reference signal resource configuration information to a serving cell. The serving cell sends a downlink reference signal measurement request including downlink reference signal resource configuration information to a terminal device. The neighboring cell and the terminal device transmit a downlink reference signal based on the downlink reference signal resource configuration information. The terminal device obtains a downlink reference signal measurement result. The terminal device sends the downlink reference signal measurement result to the serving cell. The serving cell sends the downlink reference signal measurement result to the neighboring cell, or sends, to the neighboring cell, beam information that is about a beam between the neighboring cell and the terminal device and that is determined based on the downlink reference signal measurement result.

Abstract: A positioning method relating to the field of communications technologies includes: a positioning device obtains a positioning parameter set and sends the positioning parameter set to a positioning center, where the positioning parameter set includes multipath information of a to-be-positioned terminal, and the multipath information is used to position the to-be-positioned terminal. The positioning center may position the to-be-positioned terminal by using the multipath information of the to-be-positioned terminal.
