Provided are a scheduling device and a scheduling method, in which the amount of signaling of frequency resource allocation information can be reduced while the system throughput is maintained. In a base station device (100), a scheduling unit (113) selects, as an allocation resource for a terminal to which resources are to be allocated, at most one cluster band in each of a plurality of allocatable ranges set within a system band and generates allocation resource information including information relating to the selected cluster, and an encoding unit (114), a modulation unit (115), and a transmission RF unit (116) which serve as a transmission means transmit the allocation resource information generated by the scheduling unit (113) to the terminal to which the resources are to be allocated. Among the plurality of allocatable ranges, a first allocatable range is the entire system band, while a second allocatable range is a low frequency-side band or a high frequency-side band when the system band is divided into halves.
