Enhanced discontinuous reception mechanism for power saving in TD-LTE

The battery volume of mobile terminals is limited and in most case it cannot rely on the supplying of external power. Therefore, discontinuous reception mechanism (DRX), a kind of power saving mechanism in mobile communication is introduced in order to reduce the power consumption of battery. In this paper, we discuss and show DRX parameters and features in TD-LTE. By establishing TD-LTE DRX model to the enhance DRX mechanism. Based on the analytical model, we investigate the DRX parameters and improve the power saving performance. The proper choice of these parameters (short DRX timer, long DRX timer, inactivity timer and On duration timer) allows for reducing power consumption in time and keeping the best User Experience.
