Abstract

The present invention provide a synchronization method and base station, and the method includes: determining, by a base station, a synchronization status of the base station itself, where the synchronization status includes: a synchronized base station, or, a synchronization source base station; and configuring, by the base station, according to the determined synchronization status of the base station itself, a synchronization reference signal of the base station, in order that a first time is different from a second time, where the first time is a time when the synchronization reference signal of the base station is transmitted, and the second time is a time when an inter-station synchronization reference signal of the base station's synchronization source base station is transmitted. The embodiments of the present invention can improve the synchronization performance.

Claims18

Dependent claims

A synchronization method, comprising:

determining, by a base station, a synchronization status of the base station itself, wherein the synchronization status comprises one of:
a synchronization source base station;
which acts as a synchronization source during an inter-station synchronization;
or a synchronized base station which does not act as a synchronization source and needs to be synchronized through a synchronization source base station during an inter-station synchronization;
and
configuring, by the base station, a synchronization reference signal of the base station according to the determined synchronization status of the base station itself, the synchronization reference signal including a first synchronization tracking signal indicating a first time when the synchronization reference signal of the base station is transmitted, and a second synchronization tracking signal indicating a second time when an inter-station synchronization reference signal of the base station's synchronization source base station is received by the base station, wherein the first time is different from the second time.
