Abstract

The consideration for reduced operational expenses (OPEX) and concern for carbon dioxide (CO2) emission effects on the environment has made energy efficiency a key ingredient in the design and operation of communication networks. The introduction of 5G wireless networks come along with millions of Base Transceiver Stations (BTSs) and corresponding billions of devices that can be connected to the networks. The future of radio communications is then posed for greater energy consumption. Energy-efficient wireless communication (“green” communication) is a compelling need. In this paper, analysis for exploiting sleep modes of 5G non-standalone New Radio (NSA-NR) heterogenous BTS for energy consumption optimization is provided. The analysis includes the prospects of using the sleep ratio of 4G long term evolution (LTE) and 5G NR of the heterogenous BTS to optimize energy consumption
