Abstract: Disclosed is a signaling method for a terminal that performs direct communication between terminals. A transmitting terminal transmits a link establishment request message for establishing a link to a receiving terminal, and the receiving terminal transmits a link establishment response message responding to this message to the transmitting terminal. The link establishment request message includes a field indicating a flow to use if the receiving terminal acquires a token.

Abstract: Provided is a permutated channel structure based on a block structure in talk-around direct communication. A dedicated subchannel interferes with only one adjacent dedicated subchannel, even with a large synchronization error, by permuting the dedicated subchannels by cyclic shifts, whereby a diversity gain can be maintained and interference between adjacent channels can be minimized.

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).
