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.
