COMMUNICATION SYSTEM AND BASE STATION DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a communication system and a base station device that can secure the transmittable quantity of a data signal other than a control signal by suppressing an increase in the quantity of the control signal for data transmission through an up link as much as possible.

SOLUTION: An ACK signal grouping section 108 generates a signal by adding all UE_ID information received from an ACK/NACK signal decision section 107 in a specified period together into one through bit operation and a NACK signal grouping section 112 generates a signal by adding all UE_ID information received from the ACK/NACK signal decision section 107 in the specified period together into one through bit operation. Then an ACK signal addition section 110 and a NACK signal addition section 114 generates a signal by adding information of ACK to the signals generated by the ACK signal grouping section 108 and also generate signals by adding information of NACK to the signal generated by the NACK signal grouping section 112.
