Title:
CLOCK OFFSET DETERMINATION METHOD, CLOCK OFFSET PROCESSING METHOD, DEVICE, AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/186959
Kind Code:
A1
Abstract:
The present application discloses a clock offset determination method, a clock offset processing method, a device, and a system, used to enable a base station to monitor reference signals, PRS and C-PRS, of a neighboring base station, so as to achieve time synchronization and frequency synchronization between base stations, and to resolve the issue in which a time offset caused by a frequency offset between the base stations results in the degradation of system positioning performance, thereby improving the positioning performance of the system. The clock offset determination method provided in the present application comprises: measuring a carrier-phase positioning reference signal (C-PRS) used to position a carrier phase and transmitted by a transmitter end of a positioning reference signal, so as to obtain a phase measurement value; and determining, on the basis of the phase measurement value, a clock offset between a receiver end and the transmitter end of the positioning reference signal.
