Abstract

Disclosed is a mobile communication system and a mobile communication method which enable high-quality transmission and reception of hybrid automatic repeat request (HARQ) control information when a base station apparatus and a mobile station apparatus communicate using a broad frequency band formed by a plurality of component carriers. In a mobile communication system where a base station apparatus and a mobile station apparatus communicate using a plurality of downlink component carriers, the base station apparatus allocates a physical uplink shared channel (PUSCH) resource to the mobile station apparatus for the transmission of HARQ control information, and the mobile station apparatus uses the PUSCH resource to transmit HARQ control information to the base

Claims

1. A mobile station apparatus which is set a plurality of downlink component carriers by a base station apparatus,

the mobile station apparatus comprising:

a transmitting unit which transmits information indicative of a negative acknowledgement (NACK) to the base station apparatus for a downlink transport block associated with a downlink component carrier deactivated by the base station apparatus among the set downlink component carriers.

4. The mobile station apparatus as defined in any one of claims 1 to 3, wherein

a physical downlink control channel on the deactivated downlink component carrier is not monitored.

2. A mobile station apparatus which is set a plurality of downlink component carriers by a base station apparatus,

the mobile station apparatus comprising:

a transmitting unit which transmits information indicative of a discontinuous transmission (DTX) to the base station apparatus for a downlink transport block associated with a downlink component carrier deactivated by the base station apparatus among the set downlink component carriers.

3. A mobile station apparatus which is set a plurality of downlink component carriers by a base station apparatus,

the mobile station apparatus comprising:

a transmitting unit which transmits information indicative of a negative acknowledgement (NACK)/information indicative of a discontinuous transmission (DTX) to the base station apparatus for a downlink transport block associated with a downlink component carrier deactivated by the base station apparatus among the set downlink component carriers.

5. A communication method of a mobile station apparatus which is set a plurality of downlink component carriers set by a base station apparatus,

the communication method comprising:

transmitting information indicative of a negative acknowledgement (NACK) to the base station apparatus for a downlink transport block associated with a downlink component carrier deactivated by the base station apparatus among the set downlink component carriers.

8. The communication method as defined in any one of claims 5 to 7, wherein

a physical downlink control channel on the deactivated downlink component carrier is not monitored.

6. A communication method of a mobile station apparatus which is set a plurality of downlink component carriers by a base station apparatus,

the communication method comprising:

transmitting information indicative of a-discontinuous transmission (DTX) to the base station apparatus for a downlink transport block associated with a downlink component carrier deactivated by the base station apparatus among the set downlink component carriers.

7. A communication method of a mobile station apparatus which is set a plurality of downlink component carriers by a base station apparatus,

the communication method comprising:

transmitting information indicative of a negative acknowledgement (NACK)/information indicative of a discontinuous transmission (DTX) to the base station apparatus for a downlink transport block associated with a downlink component carrier deactivated by the base station apparatus among the set downlink component carriers.

9. An integrated circuit used in a mobile station apparatus which is set a plurality of downlink component carriers by a base station apparatus,

the integrated circuit having a function of:

transmitting information indicative of a negative acknowledgement (NACK) to the base station apparatus for a downlink transport block associated with a downlink component carrier deactivated by the base station apparatus among the set downlink component carriers.

10. An integrated circuit used in a mobile station apparatus which is set a plurality of downlink component carriers by a base station apparatus,

the integrated circuit having a function of:

transmitting information indicative of a discontinuous transmission (DTX) to the base station apparatus for a downlink transport block associated with a downlink component carrier deactivated by the base station apparatus among the set downlink component carriers.

12. The integrated circuit as defined in any one of claims 9 to 11, wherein

the integrated circuit has a function of:

not monitoring a physical downlink control channel on the deactivated downlink component carrier.

11. An integrated circuit used in a mobile station apparatus which is set a plurality of downlink component carriers by a base station apparatus,

the integrated circuit having a function of:

transmitting information indicative of a negative acknowledgement (NACK)/information indicative of a discontinuous transmission (DTX) to the base station apparatus for a downlink transport block associated with a downlink component carrier deactivated by the base station apparatus among the set downlink component carriers.

14. The integrated circuit as defined in any one of claims 11 to 13, wherein

the integrated circuit has a function of:

not monitoring a physical downlink control channel on the deactivated downlink component carrier.

15. The integrated circuit as defined in any one of claims 11 to 13, wherein

the integrated circuit has a function of:

receiving, from the base station apparatus, only one transport block on the downlink component carrier.

13. An integrated circuit used in a mobile station apparatus which is set a plurality of downlink component carriers by a base station apparatus,

the integrated circuit having a function of:

transmitting, to the base station apparatus, information indicative of a negative acknowledgement (NACK)/information indicative of a discontinuous transmission (DTX) for a downlink component carrier deactivated by the base station apparatus among the set downlink component carriers.
