Abstract
Data transfer method and apparatus for use in a mobile communication system are provided. Method to perform discontinuous reception includes receiving DRX configuration information from the base station, determining a specific subframe based on parameters included in the configuration information, determining a specific point of time within the subframe based on a parameter included in the configuration information, starting onDurationTimer at the determined point of time of the determined subframe and monitoring PDCCH when the onDurationTimer is running.

- determining a point of time within the determined subframe based on 3rd DRX parameter;
- starting the onDurationTimer at the determined point of time of the determined subframe;
- starting drx-RetransmissionTimer after downlink assignment is received;
- and
- starting drx-ULRetransmissionTimer after uplink assignment is received,
- wherein the onDurationTimer, the 1st DRX parameter, the 2nd DRX parameter, the 3rd DRX parameter, the drx-RetransmissionTimer and the drx-ULRetransmissionTimer are signaled by a single RRC message,
