1. A positioning method, comprising:
determining, by a receiving device, a virtual phase measurement value according to at least two received Carrier phase Positioning Reference Signals (C-PRSs);
determining, by the receiving device, a Time Of Arrival (TOA) measurement value according to a Positioning Reference Signal (PRS) received within a same predetermined period as the at least two C-PRSs;
determining, by the receiving device, a virtual integer ambiguity for representing an integer multiple of a carrier wavelength contained in the virtual phase measurement value according to the TOA measurement value and the virtual phase measurement value; and
determining, by the receiving device, a location of the receiving device according to the virtual integer ambiguity.
