Energy Consumption Aspects of 5G Waveforms

The fifth generation mobile communications (5G) will have several advanced features with respect to the existing 4G LTE. The waveforms proposed for 5G are very much different from those of 4G and 4.5G. It is primarily due to the existing demerits of the 4G/4.5G waveforms. There are also several additional reasons why 5G should have new waveforms. Energy efficiency of 5G technologies are intended to be exemplary. In this paper, we discuss the proposed 5G waveforms and their energy efficiency issues. We compare their overall efficacy in the cellular ambient environments.
