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

摘要

A mobile station device efficiently transmits an ACK/NACK of more than 11 bits on a physical uplink channel. A mobile station device for communicating with a base station device divides a plurality of ACKs/NACKs indicating success or failure of decoding of a plurality of pieces of uplink data received from the base station device, separately encodes the divided ACKs/NACKs, and changes a method for concatenating the encoded bits of the separately encoded ACKs/NACKs in accordance with whether the ACKs/NACKs are to be transmitted on a physical uplink control channel or a physical uplink shared channel.

1. A wireless communication system comprising:
a base station device; and a mobile station device wherein the mobile station device and the base station device are configured to communicate with each other, and
the mobile station device is configured to:generate a first ACK/NACK sequence and a second ACK/NACK sequence from ACKs/NACKs for transport blocks, the transport block being received from the base station device, the first ACK/NACK sequence being different from the second ACK/NACK sequence,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,concatenate 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, andthe base station device is configured to:perform a reception process of the ACKs/NACKs.
