    Publication number: 20070237109
    Abstract: There is provided a mobile communication system capable of improving the throughput. In this system, a radio base station device (1022) waits for an upstream retransmission packet for a predetermined period of time before the moment when the retransmission time out expiration time has come and transmits a retransmission wait release request to a radio network control device (1031). When the radio base station device (1022) receives a retransmission wait release response instructing to stop the retransmission wait from the radio network control device (1031), it stops wait for the upstream packet retransmission. When the radio network control device (1031) has confirmed that the upstream packet has been received from another radio base station device upon reception of the retransmission wait release request, it creates the retransmission wait release response instruction stop of the retransmission wait and transmits it to the radio base station device (1022).
