1. An integrated circuit comprising:
reception circuitry, which in operation, controls receiving, from a base station, control information including cluster information and frequency resource information, wherein the cluster information indicates one or more clusters, and the frequency resource information indicates one or more frequency bands corresponding to the one or more clusters, wherein a size of each of the one or more frequency bands is a multiple of a product of two or more powers of prime numbers wherein the multiple is 2 or more;
transformation circuitry, which in operation, controls transforming a time signal into a frequency signal with a discrete Fourier transform (DFT) and mapping the frequency signal on the one or more frequency bands; and
transmission circuitry, which in operation, controls transmitting a transmission signal generated from the mapped frequency signal.
