<p><P>PROBLEM TO BE SOLVED: To make it possible to accurately know the number of packets which do not reach a base station among uplink transmission packets in a mobile communication system. <P>SOLUTION: A mobile terminal device of a mobile communication system in which data communication is performed between the mobile terminal device and a base station comprises: retransmission information detection means for detecting downlink retransmission information transmitted from the base station; and totalizing means for totalizing as retransmission response or non-retransmission response when the retransmission response or the non-retransmission response of the downlink retransmission information detected by the retransmission information detection means is corresponding to a previous uplink transmission packet, totalizing as untransmission when the retransmission response or the non-retransmission response of the downlink retransmission information is corresponding to a previous uplink untransmission, and transmitting the total number of the retransmission responses, the total number of the non-retransmission responses, and the total number of the untransmissions as totalized information to the base station. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
