Abstract: A method for transmitting a synchronization signal by a terminal in a direct communication network between terminals. The method for transmitting a synchronization signal by a terminal includes; randomly selecting one from a plurality of second windows included in a first window to determine the selected second window as a synchronization reception window; selecting a first synchronization slot from a plurality of synchronization slots included in the second window; transmitting a first synchronization signal from a first synchronization slot included in remaining second windows among the second windows; detecting a second synchronization signal transmitted from other terminal from the first synchronization slot included in the synchronization reception window; and determining collision of a synchronization signal based on the detection result. [Reference numerals] (AA) Synchronization slot T_sync+0; (BB) Synchronization slot T_sync+1; (CC) Synchronization slot T_sync+2; (DD,EE,FF) Super frame; (GG) T_sync window

Abstract: Provided are multicast services to a direct communication terminal not connected to a base station. Upon receiving a multicast packet from the base station, a forwarding terminal connected to the base station establishes a multicast connection with at least one direct communication terminal having a direct communication group identifier mapped to a multicast IP address of the multicast packet, and transmits the multicast packet to the at least one direct communication terminal.

Abstract: A reception terminal receives information about whether a service flow needs sequential transmission and a maximum time period, which is required to wait for non-received data when sequential transmission is needed, from a transmission terminal; restores a service data unit (SDU) from each of multiple protocol data units (PDU) received from the transmission terminal for the corresponding service flow; and sequentially transmits the restored SDUs to an upper layer according to the sequence numbers of the received PDUs. [Reference numerals] (100) First terminal;(200) Second terminal;(S300) Preamble;(S310) Transmit a link setting request message along with a RTS message (In-order delivery indicator, SDU reordering timeout);(S330) Preamble;(S350) Transmit a link setting response message along with a CTS message;(S370) Transmit a service setting message (In-order delivery indicator, SDU reordering timeout)
