Abstract: Disclosed is a wireless communication base station device capable of reducing the power consumption of a terminal when broadband transmission is performed with only an uplink. With this device, a setting unit sets mutually different terminal IDs per a plurality of uplink unit bands for a terminal that communicates using a plurality of uplink unit bands and prescribed downlink unit bands which are fewer in number than the uplink unit bands; a control unit that respectively allocates resource allocation information per a plurality of uplink unit bands to a PDCCH arranged in a prescribed downlink unit band; and a PDCCH creation unit that creates a PDCCH signal by respectively masking the resource allocation information per a plurality of uplink unit bands with the terminal ID that has been set per a plurality of uplink unit bands.
