摘要

A mobile station device efficiently transmits ACK/NACK of 11 bits or more through a physical uplink channel. The mobile station device communicates with a base station device, divides a plurality of ACK/NACK which indicate whether decoding of a plurality of pieces of uplink data received from the base station device is successful or not, encodes the divided ACK/NACK separately, associates the ACK/NACK with either being transmitted through a physical uplink control channel or being transmitted through a physical uplink shared channel, and changes a method for connecting coding bits of the separately encoded ACK/NACK.
