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 . (canceled)

2 : A mobile station device that communicates with a base station device by 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 circuitry configured to:
receive a first parameter that is used for indicating that simultaneous transmission of Hybrid Automatic Repeat Request-Acknowledgment (HARQ-ACK) and channel state information using a first physical uplink control channel format is allowed;
receive a second parameter that is used for indicating that simultaneous transmission of HARQ-ACK and channel state information using a second physical uplink control channel format is allowed; and
a determining circuitry configured to determine, in a case of collision between the HARQ-ACK and the channel state information in a same sub-frame with a physical uplink control channel, the same sub-frame being a subframe without a physical uplink shared channel, based on the first parameter, the second parameter and whether or not the HARQ-ACK corresponds to a single physical downlink shared channel transmission only on the primary cell, whether the channel state information multiplexed with the HARQ-ACK is transmitted using the first physical uplink control channel format, the channel state information multiplexed with the HARQ-ACK is transmitted using the second physical uplink control channel format, or the channel state information is dropped.

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

4 : The mobile station device according to claim 2 , wherein
in the case of collision between the HARQ-ACK and the channel state information in the same sub-frame without the physical uplink shared channel, if the simultaneous transmission of the HARQ-ACK and the channel state information using the first physical uplink control channel format is not allowed indicated by using the first parameter, if the simultaneous transmission of the HARQ-ACK and the channel state information using the second physical uplink control channel format is allowed indicated by using the second parameter, and if the HARQ-ACK corresponds to the physical downlink shared channel transmission on the secondary cell, the channel state information multiplexed with the HARQ-ACK is transmitted using the second physical uplink control channel format.

5 : The mobile station device according to claim 2 , wherein
in the case of collision between the HARQ-ACK and the channel state information in the same sub-frame without the physical uplink shared channel, if the simultaneous transmission of the HARQ-ACK and the channel state information is not allowed indicated by using the first parameter, and if the simultaneous transmission of the HARQ-ACK and the channel state information is not allowed indicated by using the second parameter, the channel state information is dropped.

6 : The mobile station device according to claim 2 , wherein
the HARQ-ACK includes information indicative of a positive acknowledgment (ACK) or a negative acknowledgment (NACK), and the channel state information includes channel state information that is periodically transmitted.

7 : A base station device that communicates with a mobile station device by using a plurality of serving cells, wherein the plurality of serving cells includes a primary cell and at least one secondary cell, the base station device comprising:
a transmitting circuitry configured to:
transmit a first parameter that is used for indicating that simultaneous transmission of Hybrid Automatic Repeat Request-Acknowledgment (HARQ-ACK) and channel state information using a first physical uplink control channel format is allowed;
transmit a second parameter that is used for indicating that simultaneous transmission of HARQ-ACK and channel state information using a second physical uplink control channel format is allowed; and
a determining circuitry configured to determine, in a case of collision between the HARQ-ACK and the channel state information in a same sub-frame with a physical uplink control channel, the same sub-frame being a subframe without a physical uplink shared channel, based on the first parameter, the second parameter and whether or not the HARQ-ACK corresponds to a single physical downlink shared channel transmission only on the primary cell, whether the channel state information multiplexed with the HARQ-ACK is received using the first physical uplink control channel format, the channel state information multiplexed with the HARQ-ACK is received using the second physical uplink control channel format, or the channel state information is dropped.

8 : The base station device according to claim 7 , wherein
in the case of collision between the HARQ-ACK and the channel state information is the same sub-frame without the physical uplink shared channel, if the simultaneous transmission of the HARQ-ACK and the channel state information using the first physical uplink control channel format is allowed indicated by using the first parameter and if the HARQ-ACK corresponds to the physical downlink shared channel transmission only on the primary cell, the channel state information multiplexed with the HARQ-ACK is received using the first physical uplink control channel format.

9 : The base station device according to claim 7 , wherein
in the case of collision between the HARQ-ACK and the channel state information in the same sub-frame without the physical uplink shared channel, if the simultaneous transmission of the HARQ-ACK and the channel state information using the first physical uplink control channel format is not allowed indicated by using the first parameter, if the simultaneous transmission of the HARQ-ACK and the channel state information using the second physical uplink control channel format is allowed indicated by using the second parameter, and if the HARQ-ACK corresponds to the physical downlink shared channel transmission on the secondary cell, the channel state information multiplexed with the HARQ-ACK is received using the second physical uplink control channel format.
