BASE STATION, TERMINAL DEVICE, CONTROL CHANNEL ALLOCATION METHOD, AND AREA SIZE DETERMINATION METHOD

摘要

It is an object to improve the frequency use efficiency of the overall system. In order to solve the object, a base station that performs radio data communication with terminal devices by using a plurality of bands of which each has a data channel region to which a data channel is assigned and a control channel region to which a control channel is assigned. The base station includes a control channel assigning unit that assigns a control channel for the terminal device at a location in the control channel region of any band of the plurality of bands according to a band to which a data channel assigned to the terminal device belongs, and a control channel transmitting unit that transmits the control channel to the terminal device at the location assigned by the control channel assigning unit.
