ABSTRACT:
Method and system by which a base station without a Global Positioning System (GPS) receiver acquires time synchronization in a Broadband Wireless Access (BWA) communication system. The method includes scanning neighbor base stations around a first base station and requesting time synchronization information from the scanned neighbor base stations by the first base station; receiving responses from predetermined neighbor base stations having already acquired time synchronization from among the neighbor base stations, the responses including time synchronization information of the predetermined neighbor base stations; and selecting a second base station from among the predetermined neighbor base stations and acquiring time synchronization based on the time synchronization information of the second base station.
