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 cell configuration method using a multi-function terminal is provided to construct cells by enabling a terminal to conduct a role of a base station in a communication system. CONSTITUTION: A terminal(110) searches bands. The terminal determines states of the bands. In case the band is an idle state, the terminal transmits a downlink frame including preamble. Other terminals(111) located within one-hop from the terminal conducts a network entry process with the terminal. The terminal optimizes transmission power. The idle band is determined when RSSI(Received Signal Strength Indication) does not over threshold values.

Abstract: PURPOSE: An idle mode management method in mobile wireless connection system and apparatus thereof are provided to offer reliable services to a user by effectively managing an idle mode. CONSTITUTION: A base station provides MBS(Multicast and Broadcast Service) to a terminal(S110). When the terminal receives the MBS, the base station creates a first idle mode starting permission message including first combination values(S120). When the terminal does not receive the MBS, the base station creates a second idle mode starting permission message including second combination values(S130). The base station transmits the first idle mode starting permission message or the second idle mode starting permission message to the terminal(S140).
