Wireless communication base station device, wireless communication terminal, and control information creation method

A method for generating control information, the method comprising:

• generating section configured to generate a plurality of control information, each of which includes both resource assignment information indicating a resource allocated to a terminal in each of multiple component carriers (CCs) configured to the terminal and information indicating each of the multiple CCs, in which resources are allocated to the terminal, the multiple CCs having frequencies different from each other;
• and
• transmitting the plurality of control information to the terminal on one CC out of the multiple CCs.

A communication device comprising:

• a generating section configured to generate first control information, which includes both resource assignment information indicating a first resource allocated to a terminal in a first component carrier (CC) out of multiple CCs configured for the terminal and information indicating the first CC, in which the first resource is allocated to the terminal, and to generate second control information, which includes both resource assignment information indicating a second resource allocated to the terminal in a second CC out of the multiple CCs and information indicating the second CC, in which the second resource is allocated to the terminal, the first CC and the second CC having frequencies different from each other;
• and
• a transmitting section configured to transmit the first control information and the second control information to the terminal on one out of the first CC and the second CC.
