METHOD AND DEVICE FOR DATA MULTIPLEXING AND INFORMATION CONTROL IN WIRELESS COMMUNICATION SYSTEMS BASED ON FREQUENCY DIVISION MULTIPLE ACCESS

Abstract

A device for transmitting data in a frequency division multiple access system is disclosed. The device includes a symbol packet generator for generating a symbol packet in a predetermined symbol packet period within a TTI transmission time interval when there is control information to be transmitted during the TTI, a Fast Fourier Transform (FFT) unit on the symbol packet, and an Inverse Fast Fourier Transform (IFFT) unit for performing IFFT on signals output from the FFT unit and then transmitting the signals. The symbol packet includes control information and data to be transmitted. The transmission time interval includes multiple symbol packet periods.
