Abstract
Embodiments of the present invention provide a synchronization method, a synchronization apparatus, and a base station, which can implement strict synchronization between base stations with relatively low costs and relatively high security and reliability. The method includes: determining reference user equipment UE, where the reference UE can communicate with a reference base station and a to-be-synchronized base station at the same time, and the reference base station and the to-be-synchronized base station have completed frequency synchronization relative to a same clock reference source; determining timing offset between the to-be-synchronized base station and the reference base station according to a moment at which the reference base station and the to-be-synchronized base station receive a synchronization reference signal that is sent by the reference UE; and performing calibration on the to-be-synchronized base station according to the timing offset.
