There is provided a base station device that communicates with a user device in a mobile communication system. The base station device comprises a means for preparing delivery confirmation information indicating whether an uplink signal received from a user device should be retransmitted or not, a means for preparing control information that permits the user device to send an up-link signal, and a means for notifying the user device of the delivery confirmation information and the control information. When the delivery confirmation information indicates a negative acknowledgement, the control information includes retransmission information indicating that an up-link signal previously transmitted by the user device should be transmitted.
