SYNCHRONIZATION METHOD, BASE STATION, NETWORK SERVER AND COMMUNICATION SYSTEM

摘要

A synchronization method, a base station, a network server and a communication system. The method involves receiving a preamble signal from a clock reference base station by a clock slave base station, detecting the preamble signal and determining a phase offset to the clock reference base station, determining a frequency offset to the clock reference base station according to the phase offset, and performing time synchronization using the determined phase offset, performing frequency synchronization using the frequency offset so as to realize the synchronization with the clock reference base station.
