Abstract

A mobile communication system, a base station device, a mobile station device, a communication method, and an integrated circuit that each can efficiently transmit HARQ-ACK and/or channel state information are provided.
A mobile station device includes means for receiving a first parameter that is used for instructing whether simultaneous transmission of information relating to HARQ-ACK and channel state information is allowed or not; and means for receiving a second parameter that is used for instructing whether simultaneous transmission of the information relating to HARQ-ACK and the channel state information is allowed or not, and controls a transmission method of the information relating to HARQ-ACK and the channel state information based on the first parameter, the second parameter, and whether or not the information relating to HARQ-ACK corresponds to transmission on a single physical downlink shared channel only on a primary cell.

First claim

1. A mobile station device that communicates with a base station device using a plurality of serving cells, wherein the plurality of serving cells includes a primary cell and at least one secondary cell, the mobile station device comprising:
a receiving unit configured to:
receive a first parameter that is used for allowing simultaneous transmission of Hybrid Automatic Repeat Request (HARQ) control information and channel state information;
receive a second parameter that is used for allowing simultaneous transmission of the HARQ control information and the channel state information using a second physical uplink control channel format; and

a determining unit configured to determine whether
the channel state information multiplexed with the HARQ control information is transmitted using a first physical uplink control channel format,
the channel state information multiplexed with the HARQ control is transmitted using the second physical uplink control channel format, or
the channel state information is dropped,
with the reference to the first parameter, the second parameter, and whether or not a single physical downlink shared channel transmission only on the primary cell indicated by a detection of a physical downlink control channel is received,
in a case of collision between the HARQ control information and the channel state information in a same sub-frame without a physical uplink shared channel.

2. The mobile station device according to claim 1 , wherein
in the case of collision between the HARQ control information and the channel state information in the sub-frame without the physical uplink shared channel,
if the simultaneous transmission of the HARQ control information and the channel state information is allowed using the first parameter and if the single physical downlink shared channel transmission only on the primary cell indicated by the detection of the physical downlink control channel is received,
the channel state information multiplexed with the HARQ control information is transmitted using the first physical uplink control channel format.

3. The mobile station device according to claim 1 , wherein
in the case of collision between the HARQ control information and the channel state information in the sub-frame without the physical uplink shared channel,
if the simultaneous transmission of the HARQ control information and the channel state information using the second physical uplink control channel format is allowed using the second parameter,
the channel state information multiplexed with the HARQ control information is transmitted using the second physical uplink control channel format.

4. The mobile station device according to claim 1 , wherein
in the case of the collision between the HARQ control information and the channel state information in the sub-frame without the physical uplink shared channel,
if the simultaneous transmission of the HARQ control information and the channel state information is not allowed the first parameter and if the simultaneous transmission of the HARQ control information and the channel state information using the second physical uplink control channel format is not allowed using the second parameter,
the channel state information is dropped.

5. The mobile station device according to claim 1 , wherein
a resource for the first physical uplink control information format is set by a higher layer.

6. The mobile station device according to claim 1 , wherein
a resource for the second physical uplink control information format is indicated using downlink control information that is transmitted on the physical downlink control channel, the downlink control information being used for indicating the resource for the second physical uplink control information format from four resources set by the higher layer.

7. The mobile station device according to claim 1 , wherein
the HARQ control information includes information indicative of a positive acknowledgment (ACK) or a negative acknowledgment (NACK).

8. The mobile station device according to claim 1 , wherein
the channel state information includes channel state information that is periodically transmitted.

9. The mobile station device according to claim 1 , wherein
the first physical uplink control channel format includes a physical uplink control channel format that is possible to transmit coded bits of 20 bits per sub-frame.

10. The mobile station device according to claim 1 , wherein
the first physical uplink control channel format includes a physical uplink control information format that is possible to transmit the channel state information multiplexed with the HARQ-ACK of 1 bit.

11. The mobile station device according to claim 1 , wherein
the first physical uplink control channel format includes a physical uplink control channel format that is possible to transmit coded bits of 21 bits per sub-frame.

12. The mobile station device according to claim 1 , wherein
the first physical uplink control channel format includes a physical uplink control information format that is possible to transmit the channel state information multiplexed with the HARQ-ACK of 2 bits.

13. The mobile station device according to claim 1 , wherein
the first physical uplink control channel format includes a physical uplink control channel format that is possible to transmit coded bits of 22 bits per sub-frame.

14. The mobile station device according to claim 1 , wherein
