Energy-efficient and QoS-aware discontinuous reception using a multi-cycle mechanism in 3GPP LTE/LTE-advanced

Energy-efficient and QoS-aware discontinuous reception using a multi-cycle mechanism in 3GPP... In the paper we present a novel energy-efficient and Quality-of-Service (QoS)-aware Discontinuous Reception (DRX) scheme by using a multi-cycle mechanism for the Long Term Evolution (LTE) networks. The proposed scheme is capable of improving the power-saving efficiency while simultaneously meeting the specific QoS requirements by dynamically tuning the DRX parameters according to the traffic intensity. It is a table-driven method which off-line pre-establishes the optimal DRX parameters corresponding to the traffic intensities and different QoS requirements such as the packet delays and packet loss rates based on a theoretical analysis approach. At runtime, the DRX parameters of each User Equipment (UE) can be determined optimally with a simple table lookup without spending much computational time and resource. The analytical model is validated against simulation experiments. Based on the analysis results, the power-saving efficiency of our proposed multi-cycle DRX scheme can be effectively boosted by about 37 % comparing to that of the typical DRX scheme while simultaneously meeting the specific QoS requirements like the packet delays and packet loss rates under the scenarios with different traffic intensities. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Telecommunication Systems Springer Journals

Abstract

In the paper we present a novel energy-efficient and Quality-of-Service (QoS)-aware Discontinuous Reception (DRX) scheme by using a multi-cycle mechanism for the Long Term Evolution (LTE) networks. The proposed scheme is capable of improving the power-saving efficiency while simultaneously meeting the specific QoS requirements by dynamically tuning the DRX parameters according to the traffic intensity. It is a table-driven method which off-line pre-establishes the optimal DRX parameters corresponding to the traffic intensities and different QoS requirements such as the packet delays and packet loss rates based on a theoretical analysis approach. At runtime, the DRX parameters of each User Equipment (UE) can be determined optimally with a simple table lookup without spending much computational time and resource. The analytical model is validated against simulation experiments. Based on the analysis results, the power-saving efficiency of our proposed multi-cycle DRX scheme can be effectively boosted by about 37 % comparing to that of the typical DRX scheme while simultaneously meeting the specific QoS requirements like the packet delays and packet loss rates under the scenarios with different traffic intensities.
