Abstract
An aspect of the invention provides a wireless communication apparatus that includes a generator configured to generate modulated signals; a mapping unit configured to map the modulated signals on at least one subcarrier in a frequency domain, the subcarrier being in a first subcarrier group corresponding to one of a plurality of subcarrier groups, wherein frequencies of the subcarrier mapped by the mapping unit is predefined by a pattern with slot, each slot including symbols in a time domain, the predefined pattern of the frequencies of each slot depending on a base station; and a transmitter configured to transmit the modulated signals mapped by the mapping unit.
