1. A radio communication control apparatus comprising:

  • a downlink control information generation section configured to generate downlink assignment information including control information for demodulation of a downlink data channel;

    an uplink control information generation section configured to generate uplink assignment information including control information for demodulation of an uplink data channel;

    a control channel multiplexing section configured to multiplex the uplink assignment information and the downlink assignment information over a control channel; and

    a transmission section configured to transmit by radio the uplink assignment information and the downlink assignment information multiplexed over the control channel, wherein;

    the downlink control information generation section is configured to;

    arrange resource allocation information related to a radio resource allocated to the downlink data channel, in the downlink assignment information, in a bitmap format;

    assign the resource allocation information, in the bitmap format, to a resource block arrangement pattern, in which a resource block group grouping a plurality of resource blocks, each of which is a minimum unit of resource allocation, is defined, and which is configured by puncturing a predetermined number of resource block groups, from a whole system band, in a predetermined pattern; and

    arrange arrangement pattern identification bits that identify a resource block arrangement pattern used to assign the resource allocation information, in a predetermined position in the downlink assignment information; and

    the uplink control information generation section is configured to;

    form the uplink assignment information in the same bit size as the downlink assignment information;

    arrange resource allocation information related to a plurality of frequency bands assigned to the uplink data channel, in the uplink assignment information, in the bitmap format; and

    include in the uplink assignment information, one of the arrangement pattern identification bits that specify the resource block arrangement pattern, as an identification bit to represent the uplink assignment information.
