1. A positioning signal processing method, wherein the method comprises:
receiving positioning reference signal (PRS) configuration information from a positioning device, wherein a PRS is received as a PRS resource set, each PRS resource set comprises one or more PRSs, and one access network device corresponds to one or more PRS resource sets;
determining PRS time domain information based on the PRS configuration information, wherein the time domain information comprises a periodicity (P) of the PRS and a symbol length of the PRS in the P;
receiving a plurality of PRSs based on the PRS time domain information;
wherein the determining the PRS time domain information based on the PRS configuration information comprises: determining a symbol length of a PRS in a first slot set, wherein the determining the symbol length of the PRS in the first slot set comprises:
determining a first symbol length of a PRS in each slot in the first slot set; and
determining the symbol length of the PRS in the first slot set based on the first symbol length;
configuring the symbol length of the PRS in the first slot set as the symbol length of the PRS in the P,
wherein the first slot set comprises a plurality of slots, and the plurality of slots are useable to transmit each PRS of the plurality of PRSs detected by the terminal device within a duration corresponding to the P.
