Abstract	The next generation of mobile communication systems is being developed for high-bandwidth mobile networks to accommodate applications with high data rates and low delay requirements such as voice over internet protocol, video streaming, cyber-physical systems and gaming. These applications consume a considerable amount of energy and hence drain the user equipment (UE) battery quickly. Long-term evolution (LTE)/LTE-advanced has adopted a discontinuous reception (DRX) mechanism to improve the energy efficiency of the UE. DRX allows UEs to monitor the physical downlink control channel in a discontinuous manner when there is no downlink traffic to reduce energy consumption. However, DRX results in higher latency due to its sleep cycle. In this study, the authors present a new scheme that improves energy efficiency in UE while maintaining an average packet delay around a permissible delay threshold. Numerical analysis and system simulation show that this scheme can achieve a significant power saving.
