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.
