Stopping of the repeated transmission of hybrid arq - data in a high speed downlink packet access (hsdpa) system

摘要

PURPOSE: An apparatus and method for retransmitting data in a mobile communication system is provided to retransmit packet data in accordance with a packet data retransmission time. CONSTITUTION: An RNC(Radio Network Controller)(430) transfers 'T1_max', the maximum standby time values of a node B T1 counter for packet data retransmission, to a node B(420) through a radio link setup request message or a radio link reconfiguration request message(401). The node B detects the maximum standby time values from the received message, sets the values for its own reordering buffers respectively, and transmits a response message(402). Receiving the response message, the RNC transmits the maximum standby time values to a UE(User Element)(410) using an RRC(Radio Resource Control) message, such as a radio bearer setup request message or a radio bearer reconfiguration request message(403). The UE detects the maximum standby time values from the received RRC message and manages the standby time of its own reordering buffers using the detected values. Then the UE transmits a response message to the RNC(404). In this manner, the radio link and radio bearer setup or reconfiguration between the node B and the UE is completed, and the communication between them is started.
