Abstract: PURPOSE: A synchronization acquisition method and apparatus thereof are provided to reduce interference between the terminals which receive services from an infrastructure of a neighbor area and a terminal in an environment where the infrastructure is not operated. CONSTITUTION: When a transmission unit(404) does not receive a preamble signal from a BS(base station), the BS transmits the first preamble signal to a synchronization point. A control unit(402) synchronizes with one or more neighbor terminals by using the first preamble signal. The control unit communicates with the one or more neighbor terminals. The first preamble signal implicitly indicates a result which the BS is collapsed. The first preamble signal is transmitted to a point which is the same as a preamble transmission point of the BS.
