Energy Efficiency Optimization by Spectral Efficiency Maximization in 5G Networks
Abstract
Energy and spectral efficiency are the main
challenges in 5th generation of mobile cellular networks.
In this paper, we propose an optimization algorithm
to optimize the energy efficiency by maximizing the
spectral efficiency. Our simulation results show a significant
increase in terms of spectral efficiency as well as
energy efficiency whenever the mobile user is connected
to a low power indoor base station. By applying the
proposed algorithm, we show the network performance
improvements up to 9 bit/s/Hz in spectral efficiency and
20 Gbit/Joule increase in energy efficiency for the mobile
user served by the indoor base station rather than by the
outdoor base station.
