Energy Efficiency Parameters Evaluation for 5G Application

Abstract

The deployment of mobile telecommunication networks has increased dramatically in recent decades. This increase in the number of mobile devices, and towers yields to increase in consumed energy. Hence, the need for energy efficiency (EE) has increased to reduce cost and pollution. In this paper, the following parameters are studied to enhance EE: increasing the number of base station antennas, increasing the number of user equipment (UEs), and other parameters such as channel state information (CSI). The purpose of this study is to look into how improvement might be achieved. Using the MATLAB program, this article analyzes and enhances EE using a mathematical model in the fifth generation of wireless communication (5G) massive multiple-input multiple-output (Massive-MIMO). The EE effectiveness is demonstrated through simulation results and shows how different parameter selections affect the fundamental balance between EE and spectral efficiency (SE) or only on the EE. The results show that a couple of parameters enhance the EE-SE curve, such as the number of base station antenna, transmit bandwidth, circuit power, number of users, and the availability of CSI. The increase in the number of base station antennas is considered to be a simple solution to increase the EE before the increase in circuit power. Increasing the number of antennas, also, reduces the impact of having imperfect CSI. The results show an increasing number of antennas with respect to the number of users from 4 to 10 do not increase EE, yet increase the SE by around %55.
