There are disclosed a wireless communication apparatus and a wireless communication method whereby a flexible frequency scheduling can be performed without increasing the circuit scale of DFT (Discrete Fourier Transform). In a terminal (200), a number-of-allocated-RBs setting unit (209) sets a number of allocated RBs, which is to be used for an actual transmission band corresponding to the number of notified RBs, to a number of resource blocks that can be expressed by one of “2n×3m×5l”. The allocated RB selecting unit (210) selects, based on the resource allocation information and the number of allocated RBs, either an unused one of the notified RBs that is not used as the transmission band or an additional RB that is added to the notified RBs and used as the transmission band.
