PROBLEM TO BE SOLVED: To provide a radio communication device, an integrated circuit, a transmission method, a reception method and a communication method that can improve a reception characteristic when reception is performed while moving.SOLUTION: A radio communication device has a symbol mapper, a subcarrier mapper and an inverse Fourier Transform processor. The radio communication device is connected to plural antennas. The symbol mapper maps a data sequence containing contents for mobiles onto modulation symbols. The subcarrier mapper allocates the modulation symbols to plural subcarriers contained in transmission signals transmitted from the respective antennas. At this time, the modulation symbols are allocated to subcarriers which are selected at a predetermined interval from sequential subcarriers contained in a frequency band for transmission of the contents for the mobiles out of the plural subcarriers, and 0 is allocated to the other subcarriers of the frequency band. The inverse Fourier Transform processor is provided every antenna, and transforms the signals of the plural subcarriers to transmission signals by inverse Fourier Transform.SELECTED DRAWING: Figure 5 |
