Abstract
A radio transmission device includes a transmitter () and a controller (). The transmitter () transmits a radio signal in which a demodulation reference signal is mapped. When a plurality of the demodulation reference signals are to be mapped respectively to first and second unit resources consecutive in a time domain of the radio signal, the controller () applies the same sequence to each of the plurality of the demodulation reference signals to be mapped to the first and the second unit resources.
