ABSTRACT
Wireless technologies have been growing rapidly in all corners of the world. Fifth-generation (5G) wireless technology has emerged as one of wireless research’s most exciting and challenging topics. As a multiservice network, 5G is expected to accommodate a broad variety of industries, each with its own set of performance and service needs. To meet the increased demand for mobile connections, 5G delivers new radio (NR) technology, and we review the essentials of future mobile communications regarding the introduction of 5G NR; we explain multiple-input/multiple-output antennas, radio access networks, and frequency bands. We also review the convergence of wireless communication, the supporting technological drivers, and spectra regarding the 5G NR environment to examine NR applications in 5G networks. We outline some of the most essential research areas in 5G NR in this chapter.
