Title:
METHOD AND DEVICE FOR CONTROLLING PHASE SYNCHRONISATION, AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2016/061793
Kind Code:
A1
Abstract:
The present invention relates to a method and device for controlling phase synchronisation, and a system. The method comprises: determining a path from a non-reference base station to a preset reference base station and obtaining various first phase differences between various adjacent base stations on the path, obtaining a second phase difference between the reference base station and the non-reference base station according to the various first phase differences, and adjusting a non-reference phase of the non-reference base station to a reference phase of the reference base station according to the second phase difference. The method and device for controlling phase synchronisation and the system provided by the present invention implement phase synchronisation between base stations within a single-frequency network system without it being necessary for a GPS antenna to be installed, thereby reducing system costs.
