Wireless communication system, mobile station device, base station device, wireless communication method, and integrated circuit

A base station device configured to communicate with a mobile station device, the base station device comprising:

• reception circuitry configured to perform a reception process of ACKs/NACKs;
• and
• transmission circuitry configured to transmit transport blocks to the mobile station device, wherein
• a first ACK/NACK sequence and a second ACK/NACK sequence are generated from the ACKs/NACKs for the transport blocks, the transport blocks being transmitted from the base station device, the first ACK/NACK sequence to generate a first coded bit sequence being encoded, the second ACK/NACK sequence to generate a second coded bit sequence being encoded, the first ACK/NACK sequence and the second ACK/NACK sequence being separately encoded by using a same set of base sequences, the first coded bit sequence and the second coded bit sequence being concatenated, differently based on whether the ACKs/NACKs are to be transmitted on a physical uplink control channel or on a physical uplink shared channel.

A wireless communication method used in a mobile station device that is configured to communicate with a base station device, the wireless communication method comprising:

• generating a first ACK/NACK sequence and a second ACK/NACK sequence from ACKs/NACKs for transport blocks, the transport blocks being received from the base station device, the first ACK/NACK sequence being different from the second ACK/NACK sequence;
• encoding the first ACK/NACK sequence to generate a first coded bit sequence, and encode the second ACK/NACK sequence to generate a second coded bit sequence, the first ACK/NACK sequence and the second ACK/NACK sequence being separately encoded by using a same set of base sequences;
• and
• concatenating the first coded bit sequence and the second coded bit sequence differently based on whether the ACKs/NACKs are to be transmitted on a physical uplink control channel or on a physical uplink shared channel.

An integrated circuit used in a mobile station device that is configured to communicate with a base station device, the integrated circuit comprising:

• generating circuitry configured to generate a first ACK/NACK sequence and a second ACK/NACK sequence from ACKs/NACKs for transport blocks, the transport blocks being received from the base station device, the first ACK/NACK sequence being different from the second ACK/NACK sequence;
• encoding circuitry configured to encode the first ACK/NACK sequence to generate a first coded bit sequence, and encode the second ACK/NACK sequence to generate a second coded bit sequence, the first ACK/NACK sequence and the second ACK/NACK sequence being separately encoded by using a same set of base sequences;
