In a terminal (200), a radio transmitter (209) transmits a signal, and a controller (204) determines an allocation resource to which a signal is assigned in a predetermined frequency band. The predetermined frequency band herein is divided into a plurality of bands, and each of the plurality of bands includes a plurality of frequency resources which are base units of resource allocation for the signal. Furthermore, the allocation resource to which the signal is assigned is composed of at least one of the base units of each of the plurality of bands. Furthermore, a configuration method of the at least one of the base units forming the allocation resource is different for each of the plurality of bands.
