Abstract: This application provides a positioning reference signal PRS association method and a communication apparatus. The method includes: A terminal device receives second configuration information sent by a positioning management device, where the second configuration information indicates an association relationship between PRSs on at least two frequencies; and the terminal device measures the PRSs having the association relationship, where the PRSs having the association relationship share a same antenna port or the PRSs having the association relationship have a phase difference. By implementing this application, large-bandwidth PRS configuration can be implemented.

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: The technology of this application relates to a positioning method and apparatus. In one example embodiment, a network server can receive N pieces of phase information sent by a first communication device, where the N pieces of phase information are obtained based on one or more reference signals sent by a second communication device, and then determine a distance between the first communication device and the second communication device based on the N pieces of phase information. According to the positioning method provided in this application, measurement accuracy of the measured distance between the first communication device and the second communication device can be improved.
