Tradeoff Between Performance and Energy-Efficiency in DRX Mechanism in LTE-A Networks

Abstract

One of the most concerning issues in current wireless technology is managing the energy consumption in the User Equipment (UE). LTE-A brings along with its massive data transmission speeds with a caveat of heavy energy consumption. Energy saving albeit, comes at the cost of Quality of Service (QoS), which is the delay in serving packets in the UE. The Discontinuous Reception Scheme (DRX) is an energy saving scheme in LTE-A networks. Given the parameters of DRX, there is a tradeoff between the energy saving and QoS. The modelling and theoretical results for one-way and two-way communications with DRX are presented in [2]. In this paper, the simulation results of one-way and two-way communications with the DRX scheme are presented.
