Abstract:
In order to reduce radio resources allocated to PDCCHs and improve the data rate even when a plurality of component carriers are aggregated into a wide band, the present invention provides a base station apparatus having: a downlink control information generation section (306) configured to generate downlink control information (DCI) to demodulate PDSCHs that are sent independently in respective component carriers (CCs) allocated to a user terminal; and a transmitting section configured to transmit a PDCCH containing the downlink control information (DCI). The downlink control information (DCI) generated by the downlink control information generation section (306) is added with identification information (CIF) that is used to demodulate the PDSCHs assigned to the component carriers and is capable of identifying each of the component carriers.
