METHOD AND APPARATUS FOR TRANSMITTING DATA IN A DEVICE TO DEVICE COMMUNITION SERVICE SYSTEM

摘要

PURPOSE: A data transmission method and a device thereof are provided to effectively transmit data in a D2D(Device to Device) service. CONSTITUTION: A control unit(605) overhears data transmitted from a first device to a third device through a reception unit. The control unit overhears a response signal transmitted from the third device to the first device. The control unit confirms a transmission failure data block of the first device. When data transmission resources are remained in a data transmission point according to predetermined scheduling, the control unit generates transmission data by including the transmission failure data block of the first device in the transmission data of the second device.
