Claim 3:
4. A transmission method comprising:
generating, based on data, a first signal to be transmitted according to single carrier block transmission;
generating, based a known signal, a second signal to be transmitted according to orthogonal frequency division multiplex transmission;
controlling generation of the second signal such that, in a first transmission period, the known signal is a reference signal used for demodulating the first signal in the second transmission period and is arranged in discontinuous frequency bands assigned by a receiving apparatus for transmitting the known signal from a transmitting apparatus among frequency bands available in the orthogonal frequency division multiplex transmission;
selecting and outputting the second signal in the first transmission period and the first signal in a second transmission period notified by the receiving apparatus; and
transmitting the first signal and the second signal.
