To transmit resource allocation information on a plurality of radio resources to a terminal, a resource allocation device expresses a radio resource that is differently allocated from before the resource allocation information is transmitted among the plurality of radio resources in a radio resource pattern sequence, generates resource allocation information on the plurality of radio resources based on the radio resource pattern sequence, and transmits the radio resource pattern sequence and the resource allocation information, or a compressed pattern sequence corresponding to the radio resource pattern sequence and the resource allocation information, to the terminal through a frame.
