Nowadays, the Non-Orthogonal Multiple Access (NOMA) has become the most candidate as the multiple access technique for the Fifth Generation (5G). Although, the massive increase in traffic usage is necessary, but it must not come on the account of Energy Efficiency (EE). Therefore, Green Radio (GR) which one of its main points is energy efficiency (EE) gained a lot of attention in last few years in both academic and industrial fields. In this paper, the Energy-Efficiency in the NOMA downlink system under the effect of the Nakagami-m fading channel is studied. Moreover, the Nakagami-m fading channel can tackle several fading cases according to the parameter m . The system has been solved via an iterative algorithm to investigate the required power level for maximum energy efficiency. Different channel models will be investigated such as: one-sided Gaussian faded channel, Rayleigh faded channel, Raician (Nakagami-n) faded channel, and LOS.
