Claim 1:
2. The method of claim 1, wherein the determining, by the receiving device, the TOA measurement value according to the PRS, received within the same predetermined period as the at least two C-PRSs, comprises:
when the receiving device receives a PRS from a transmitting device, determining a non-differential TOA measurement value according to the PRS through a TOA measurement algorithm operation; or
when the receiving device receives PRSs from at least two transmitting devices, one of the at least two transmitting devices is a reference transmitting device, and one of the at least two transmitting devices other than the reference transmitting device is a non-reference transmitting device, obtaining at least two non-differential TOA measurement values according to the PRSs through a TOA measurement algorithm operation, and determining a single-differential TOA measurement value by performing a differential operation on the at least two non-differential TOA measurement values of the reference transmitting device and the non-reference transmitting device; or
when at least two transmitting devices transmit PRSs to multiple receiving devices and one of the at least two transmitting devices is a reference transmitting device and one of the multiple receiving devices is a reference receiving device with a known location, performing, by each of the multiple receiving devices, TOA measurement algorithm operations and single differential operations on the PRSs transmitted by the at least two transmitting devices to obtain a single-differential TOA measurement value of each of the multiple receiving devices, and then performing a differential operation on the single-differential TOA measurement value of each of the multiple receiving devices to obtain a dual-differential TOA measurement value.
