SYNCHRONIZATION METHOD AND BASE STATION
First Claim
1. A synchronization method, comprising:
- receiving, by a first base station, on at least one part of channels in a receiving band supported by the first base station, at least one first downlink synchronization signal sent by at least one second base station;
selecting, by the first base station, a first downlink synchronization signal from the at least one first downlink synchronization signal; and
executing, by the first base station, time synchronization according to the selected first downlink synchronization signal.

Abstract
Embodiments of the present application provide a synchronization method and a base station. In the embodiments of the present application, a first base station receives, on at least one part of channels in a receiving band supported by the first base station, at least one first downlink synchronization signal sent by at least one second base station, and selects a first downlink synchronization signal from the at least one first downlink synchronization signal, to enable the first base station to execute time synchronization according to the selected first downlink synchronization signal, which can avoid a problem in the prior art of low reliability of time synchronization caused by low availability of a GPS signal, and relieve interference suffered by a base station from another base station caused by a problem of asynchronous receiving and sending time or inaccurate time synchronization, thereby improving signal quality of an air interface.
