一种频率同步的方法、基站和系统技术方案

本发明专利技术实施例涉及通信领域，尤其基站的频率同步。在一种频率同步的方法中，第一基站获取第二基站的第二频率偏移量，以及确定第一基站和第二基站之间的频率差，并根据第二频率偏移量和该频率差确定第一基站的第一频率偏移量，以及根据第一频率偏移量进行频率同步。通过本发明专利技术实施例的方案，第一基站可以在不依赖同步以太网的情况下，通过第一基站与第二基站之间的交互确定第一基站的第一频率偏移量，从而进行频率同步。

A Frequency Synchronization Method, Base Station and System

The embodiment of the present invention relates to the field of communication, especially the frequency synchronization of base stations. In a method of frequency synchronization, the first base station obtains the second frequency offset of the second base station and determines the frequency difference between the first base station and the second base station, and determines the first frequency offset of the first base station based on the second frequency offset and the frequency difference, as well as frequency synchronization based on the first frequency offset. According to the scheme of the embodiment of the present invention, the first base station can determine the first frequency offset of the first base station through the interaction between the first base station and the second base station without relying on the synchronous ethernet, thus frequency synchronization can be carried out.
