Claim 13:
14. The device of claim 13, wherein the processor is configured to:
when a PRS is received from a transmitting device, determine a non-differential TOA measurement value according to the PRS through a TOA measurement algorithm operation; or
when PRSs are received 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, obtain at least two non-differential TOA measurement values according to the PRSs through a TOA measurement algorithm operation, and determine 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 PRSs are received by multiple receiving devices from at least two transmitting 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, perform 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 perform 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.
