ABSTRACT:
In a retransmission control method and device which can suppress or expedite a retransmission of user data depending on a processing congestion status or the like on a receiving side, a user equipment on a data receiving side transmits to a radio network control device on a data transmitting side, when redundantly receiving an ACK request included in same user data, control data for extending a timeout period of a polling timer which is a retransmission time interval of user data for a subsequent ACK request by e.g. 10 ms. The radio network control device having received the control data extends the timeout period based on the control data. Alternatively, the radio network control device reduces, when receiving an ACK response from the user equipment within the timeout period, a timeout period of user data for a subsequent ACK request to less than the timeout period presently set.
