PURPOSE: A method and a device for transmitting data in a wireless communication system, and a transmitter are provided to improve communication efficiency by variably setting an interval of subcarriers. CONSTITUTION: The first data converted into a time domain signal by subcarriers with a first subcarrier interval is transmitted to at least one terminal or more. The second data converted to the time domain signal by the subcarriers with a second subcarrier interval different from the first subcarrier interval is transmitted to at least one terminal or more. The first data and the second data are transmitted in the different cells. A symbol mapping module(12) outputs the symbol sequence by symbol-mapping the binary data. A frequency-time conversion module converts the symbol sequence into the time domain symbol using a plurality of subcarriers with variable subcarrier intervals. A cyclic prefix adding module adds the cyclic prefix to the time domain symbol. A protection section insertion module(16) generates the protection section by inserting the cyclic prefix or cyclic postfix to the symbol outputted from a P/S conversion module(15). |
