<p>Embodiments of the present invention provide a timing synchronization method and apparatus, a user equipment, and a communications system, which relate to the field of communications. The method comprises: a first base station sending first signaling to a UE; the UE sending second signaling to a second base station; the second base station sending third signaling to the UE; the UE sending to fourth signaling to the first base station; the first base station obtaining a timing deviation between the first base station and the second base station according to the time of sending or receiving the first signaling, the second signaling, the third signaling and the fourth signaling; and the first base station or the second base station adjusting timing by using the timing deviation. In the present invention, signaling is transmitted between two base stations and a UE, and a timing deviation between the two base stations is determined according to sending time and receiving time of the signaling, and further timing of the base stations are adjusted to implement timing synchronization of the two base stations, thereby avoiding the problem in the prior art that mutual interference exists between synchronization reference signal reception and synchronization reference signal sending when timing synchronization is performed by using a synchronization reference signal.</p> |
