Abstract: PURPOSE: A method for performing direct communications between terminals and the terminal supporting the same are provided to obtain synchronization between the terminals performing direct communications by improving a synchronization channel structure. CONSTITUTION: Direct communications is performed with one or more second terminals using allocated resources for the direct communications between terminals. The resources include a synchronous channel which is used for frequency synchronization and time synchronization between the terminals. The synchronization channel includes a synchronization channel preamble which is used for either preamble detection, time offset estimation, frequency offset estimation, or channel estimation. The synchronization channel preamble is either a first sequence repeating a basic pattern or a second sequence combining the basic pattern with a pattern multiplying the basic pattern by (-1). One or more OFDM(orthogonal frequency division multiplexing) symbols are used for transmitting the synchronization channel preamble.

Abstract: PURPOSE: A femto cell search method for macro to femto handover is provided to minimize the MAC(Media Access Control) overhead by excluding the neighbor femto cell list within the base station advertise message MOB NBR ADV(Mobile Neighbor Advertisement) message which the macro cell transmits. CONSTITUTION: A terminal broadcasts the respective dummy preamble to the exclusive symbol assigned in the first base station(S130). The terminal decides the dummy preamble coincides for the triggering condition(S150). The terminal creates the femto cell information request message in the first base station(S160). The first base station transmits the femto cell information response message in the terminal(S190). The femto cell information response message comprises the neighbor femto cell list about obtained femto cell IDs. The terminal looks for the candidate base station(S200).
