Zusammenfassung:	A wireless communication method is provided for a transmission apparatus that transmits an OFDM (orthogonal frequency division multiplexing) signal using a communication band that comprises a plurality of subcarrier groups each including a plurality of subcarriers. The method includes specifying which subcarrier group and how many subcarriers are to be used to transmit the OFDM signal and determining a configuration of a transmission frame, generating the OFDM signal by mapping data symbols according to the determined configuration of the transmission frame, and transmitting the generated OFDM signal. The number of subcarriers to be used to transmit the OFDM signal is variable, the OFDM signal may be generated using a plurality of modulation schemes including QPSK and 16QAM, and a plurality of mapping patterns are prepared for each of the plurality of modulation schemes.
