METHOD OF TRANCEIVING FOR DEVICE-TO-DEVICE COMMUNICATION AND TERMINAL APPARATUS HAVING TRANCEIVER FOR THE SAME |
摘要 |
PURPOSE: A transmission and reception method for direct communication between the terminals is provided to directly support direct communication between the terminals in a mobile communication system. CONSTITUTION: A first switching unit(410) determines the application of DFT(Discrete Fourier Transform) according to a transmission method selected based on information for selecting a transmission method. A second switching unit(420) applies the P/S(Parallel-to-Serial) of a frequency surface or the P/S of a time surface according to the selected transmission method. The first switching unit controls the application of DFT for a modulation symbol outputted from a modulation symbol mapping unit. The second switching unit applies the P/S of the frequency surface of the P/S of a time surface to the output of a CP(Cyclic Prefix) adding unit.
