Half-Duplex Radio: Toward Green 5G NR

The standardization of the 5th generation of mobile communication networks is paving its way in 3GPP, involving the evolution of 5G New Radio (NR). One of the key features of NR is its operation at high frequencies, such as mmWave, involving high human exposure to electromagnetic radiation in the atmosphere. This increases the power density levels in our ecosystem, high specific absorption rates in body tissues because of temperature elevation due to heating. This article provides an overview of the harmful impacts of the Radio Frequency fields with some radiation reduction techniques. A potential solution as a proposal in the form of “Thermal Radiation” (TR) mode to design the future mobile communication networks is presented. The proposed mode validates its performance by decreasing Power Density, complexity, and temperature elevation. Also high energy efficiency is obtained for the proposed TR mode, hence contributing toward Green Communication.
