1. An operating method of a Relay Station (RS) supporting a Layer-3 (L3) relay communication in a wireless communication system, the method comprising: establishing a first connection with a Base Station (BS) by performing a network entry procedure as a Mobile Station (MS); establishing a second connection with a MS by performing a network entry procedure as a BS; receiving at least one Media Access Control (MAC) Protocol Data Unit (PDU) including traffic from the MS through the second connection; generating an L3 packet, which is fragmented into the at least one MAC PDU, from the at least one MAC PDU, wherein the L3 packet comprises an Internet Protocol (IP) packet; generating at least one relay MAC PDU including the L3 packet generated from the at least one MAC PDU, without at least one header of the at least one MAC PDU; and transmitting the at least one relay MAC PDU including the L3 packet using a RS Service Flow (SF) for a traffic, of a same Quality of Service (QoS) as QoS required by MS SFs carrying the L3 packet from the MS to the RS to the BS through the first connection.
