Abstract: The present invention provides a method for forwarding an uplink packet performed by a node in a wireless communication system, the method being characterized in that the uplink packet including a first cost is received, the first cost is compared with a second cost corresponding to a cost of the node to determine whether to forward the uplink packet, and on the basis of the determination the uplink packet is forwarded, the node forwards the uplink packet when a value of the second cost is smaller than a value of the first cost, and the node does not forward the uplink packet when the second cost value is not smaller than the first cost value.

Abstract: Disclosed are a method for transferring data in a wireless communication system that supports device-to-device communication, and an apparatus therefor. Specifically, a method for performing, by a device, data transfer in a wireless communication system that supports device-to-device communication, comprises the steps of: broadcasting, at a first sub-carrier, a ready-to-forward (RTF) signal for advertising that the device holds data to transfer; receiving, at a second sub-carrier, a forward-request (FR) signal for requesting transfer of the data from another device; and broadcasting the data after a predetermined time, wherein the first sub-carrier and the second sub-carrier are determined on the basis of sequence numbers of the data, respectively.
