Abstract: The present invention relates to a method for transmitting information for synchronization of a user equipment by a base station in a wireless communication system and apparatus for the same. In one embodiment of the present invention, a source base station transmits a request message requesting uplink synchronization information according to a predetermined reference to a target base station, receives a response message including the synchronization information from the target base station in response to the requested message, and transmits the received synchronization information to one or more user equipments which are to move to a cell serviced by the target base station. The synchronization information is used when the user equipments move to the cell serviced by the target base station without a process of acquiring the synchronization information.
