Claim 3:
4. The method of claim 3, wherein the determining, by the receiving device, the actual phase measurement value corresponding to each C-PRS of the at least two C-PRSs, comprises:
when the receiving device receives at least one C-PRS from a transmitting device, determining a non-differential actual phase measurement value according to the at least one C-PRS through a carrier phase measurement algorithm operation; or
when the receiving device receives the at least two C-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 carrier phase measurement values according to the at least two C-PRSs through carrier phase measurement algorithm operations, and determining a single-differential actual phase measurement value by performing a differential operation on the at least two non-differential carrier phase measurement values of the reference transmitting device and the non-reference transmitting device; or
when at least two transmitting devices transmit the at least two C-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, carrier phase measurement algorithm operations and single differential operations on the at least two C-PRSs transmitted by the at least two transmitting devices to obtain a single-differential carrier phase measurement value of each of the multiple receiving devices, and then performing a differential operation on the single-differential carrier phase measurement value of each of the multiple receiving devices to obtain a dual-differential actual phase measurement value.
