Abstract: Positioning methods and apparatus are provided to implement high-precision positioning while a device is in a moving state can implement high-precision positioning. The positioning method includes receiving a first receive-transmit time difference and a displacement vector of a second device, and determining a location of a first device based on the first receive-transmit time difference, the displacement vector of the second device, and a second receive-transmit time difference. The method may be applied to the first device. The first device may determine a transmission distance of a reference signal between the two devices based on the first receive-transmit time difference and the second receive-transmit time difference, and may determine a relative displacement between the two devices based on the displacement vector of the second device.

Abstract: This application provides a communication method and a communication apparatus. In comparison with an implementation in which a first device performs positioning based on measurement results corresponding to reference signals transmitted on a plurality of paths, a first measurement result sent to the first device is a measurement result corresponding to a first reference signal transmitted on a single path. In this way, interference of multipath transmission can be avoided in a process in which the first device performs positioning based on the first measurement result, and positioning accuracy is improved. In the method, the communication apparatus receives first request information from the first device, and the first request information is used to request to report the measurement result of the first reference signal. The communication apparatus measures the first reference signal transmitted on a first path, to obtain the first measurement result.

Abstract: A positioning signal processing method includes receiving positioning reference signal (PRS) configuration information from a positioning device. A PRS is received as a PRS resource set. Each PRS resource set includes one or more PRSs. One access network device corresponds to one or more PRS resource sets. The positioning signal processing method further includes determining PRS time domain information based on the PRS configuration information. The time domain information includes a periodicity (P) of the PRS and a symbol length of the PRS in the P. The positioning signal processing method further includes receiving a plurality of PRSs based on the PRS time domain information.

Abstract: The present disclosure relates to reference signal resource configuration methods and apparatus. In one example reference signal resource configuration method, a terminal receives sounding reference signal (SRS) resource configuration information from a base station. In response to determining that at least two SRS resources indicated by the SRS resource configuration information are located on a same orthogonal frequency division multiplexing (OFDM) symbol, the terminal maps one of the at least two SRS resources to the OFDM symbol.

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 relative angle-based positioning method and an apparatus. In the method, a network device can flexibly select a reference direction, and support linear array-based angle positioning. The method includes: A network device participating in positioning exchanges an uplink positioning configuration with a positioning center, a terminal device, and a serving cell that participate in positioning. The network device participating in positioning receives a first reference signal sent by the terminal device. The network device participating in positioning determines angle measurement information based on the first reference signal. The network device participating in positioning reports the angle measurement information to the positioning center, where the angle measurement information includes a set reference direction and an angle of a direction of the terminal device relative to the set reference direction. The positioning center determines a location of the terminal device based on the received angle measurement information.
