Abstract
A communication control device including: an acquisition unit configured to acquire band use information indicating which cell of a macro cell and a small cell partially or entirely overlapping with the macro cell uses each of a plurality of frequency bands used by one of the macro cell and the small cell; and a communication control unit configured to notify a terminal device of the band use information. The communication control device improves radio communication of a terminal device when a small cell is disposed.

1-19. (canceled)
A communication control device comprising:
- circuitry configured to communicate with a terminal device, the terminal device configured to communicate with a first communication device and a second communication device using a plurality of component carriers configured by carrier aggregation, the plurality of component carriers including a component carrier of a first type which is changeable by a handover procedure and a component carrier of a second type which unchangeable by the handover procedure,
- wherein:
- each of the plurality of component carriers is used by one of a first communication link between the terminal device and the first communication device and a second communication link between the terminal device and the second communication device,
- a first control signal for one or more component carriers of the second type in the first communication link is transmitted via a component carrier of the first type in the first communication link,
- a transmission, via the component carrier of the first type in the first communication link, of a second control signal for one or more component carriers of the second type in the second communication link is restricted, and
- the second control signal is transmitted via a component carrier of the first type in the second communication link.
