Abstract: The enormously enhancing the evolution of forthcoming generations, the fifth-generation wireless technology continuously developed and extent to more progressive. The field of mobile technology provides improved network capacity, low latency, great availability, more reliability with intense speed. This paper introduces an overview of fifth-generation wireless technology accompanied by five other major technologies of 5G namely millimeter wave, small cells, Massive MIMO, Beamforming, and Full-duplex respectively. In addition, Energy Efficiency (EE) is an enormous strategy that immensely declines the circuit power consumption in fifth-generation cellular networks. This consequence is enhanced due to the rising number of antennas in massive multiple-input multiple-output (MIMO) systems. Energy efficiency has now become a fundamental aspect in the framework of communication networks. With the arrival of the fifth generation of wireless networks, with millions of additional base stations and billions of connected devices, the demand for energy-efficient system design and operation will be even more fascinating. Further, this paper outlines the various research work related to energy efficiency including the papers published in this special issue, and considers the most compelling research challenges to be discussed in the upcoming generation.

Keywords: 5G,Massive MIMO, Millimeter wave, small cells, Beamforming, Full duplex, heterogeneous networks, Energy Efficiency (EE).
