Abstract:
1. A method for improving discontinuous reception for a user equipment of a wireless communication system, the user equipment controlling retransmission reception timings of a plurality of downlink hybrid automatic repeat request (DL HARQ) processes by use of a discontinuous reception retransmission timer (DRX retransmission timer), the method comprising: when receiving a retransmission packet of a first DL HARQ process of the plurality of DL HARQ processes during a running state of the DRX retransmission timer, determining a state of packet data stored in a buffer, which is used for storing packet data related to the plurality of DL HARQ processes; keeping the running state of DRX retransmission timer when determining that the packet data stored in the buffer includes decoding failure data which does not belong to the first DL HARQ process; and stopping the DRX retransmission timer when determining that the packet data stored in the buffer does not include the decoding failure data which does not belong to the first DL HARQ process.
