The present invention is a wireless communication system having a mobile station and a wireless base station, wherein the wireless base station further having a scheduling processing unit which divides system bandwidth into a plurality of wireless resource blocks in a frequency domain, performs scheduling so that other channels are not assigned to the wireless resource blocks which are adjacent to a first channel when the first channel whose frequency characteristic is not orthogonal to the other channels is assigned to a certain wireless resource block resulting from the division, and creates scheduling information on the scheduling that is performed; and a transmission unit which transmits the scheduling information created by the scheduling processing unit to the mobile station, and the mobile station transmits a channel signal to the wireless base station on the basis of the scheduling information and the wireless base station receives the channel signal transmitted from the mobile station.
