Energy efficient discontinuous reception strategy in LTE and beyond using an adaptive packet queuing technique
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.
