Abstract  Abstract

A base station apparatus communicating with a user equipment terminal in a mobile communication system is disclosed. The base station apparatus includes a determination unit determining whether an uplink signal received from the user equipment terminal is to be retransmitted a control information generation unit generating control information to permit the user equipment terminal to transmit an uplink signal and a transmission unit transmitting the control information to the user equipment terminal. Further in the base station apparatus when the determination unit determines that the uplink signal is to be retransmitted the control information generation unit generates the control information so as to include retransmission information indicating that an uplink signal transmitted before from the user equipment terminal is to be retransmitted.
