Abstract

Embodiments of the present application provide a resource setting method and a communication device. According to the method provided in the present application, a network device receives first reference SRS resource information from a location management device, and based on the first reference SRS resource information, sets a second SRS resource for a terminal device to be positioned, and the network device sets a second SRS resource having at least one overlapping time domain unit with the first SRS resource related to the first reference SRS resource information for the terminal device to be positioned. Further, by measuring the SRS signal transmitted by the reference terminal device on the first SRS resource and the SRS signal transmitted by the terminal device to be positioned, when the terminal device to be positioned is positioned, the phase shift present in the phase measured by the network device on the first SRS resource in the time domain and the phase shift present in the phase measured by the network device on the second SRS resource in the time domain are the same or similar. This helps to remove or reduce the error introduced by the phase shift and improve the positioning accuracy.
