Patent ID: 8527827

Claim:
An orthogonal frequency division multiplexing transmission method that transmits an orthogonal frequency division multiplexing (OFDM) signal, comprising: generating a data symbol; generating a control information signal including a modulation scheme information and an error correction scheme information of a data symbol; and forming the OFDM signal including the data symbol and the control information signal, wherein the control information signal is arranged in a first plurality of subcarriers in a time period and a second plurality of subcarriers in the time period, and the data symbol is arranged in a location different from the control information signal in the first plurality of subcarriers in the time period and the second plurality of subcarriers in the time period, the first plurality of subcarriers and the second plurality of subcarriers are subcarriers included in the OFDM signal in the time period, and the first plurality of subcarriers are different from the second plurality of subcarriers.
