ABSTRACT:
An apparatus and method for synchronization between uncoordinated Time Division Duplex (TDD) communication networks includes a first step (300) of measuring an interference level on channels available to a base station. A next step (302) includes choosing the channel having the lowest interference level. A next step (304) includes determining that the interference is from a base station. A next step (306) includes calculating an interference profile over the frame cycle. A next step (308) includes establishing a peak interference level. A next step (310) includes aligning the base station frame timing in response to the peak interference level.
