A method and apparatus for frame synchronization in a communication network is provided. The communication network includes a plurality of base stations. The method includes determining the start time of reception of a downlink frame received from each of at least a second base station. The method also includes determining the radio frequency propagation delay associated with the downlink frame received from the each of at least a second base station. Further, the method includes determining the reference downlink frame transmission time at the first base station, based on the reception start time of the downlink frame and the radio frequency propagation delay associated with one of the at least a second base station.
