| Abstract | Massive MIMO is one of the promising techniques to improve spectral efficiency and network
performance for reaching its targeted multi-gigabit throughput in 5G systems. For 5G New Radio (NR)
systems, one of the key differences compared to 4G systems is the utilization of high frequency millimeter
wave (mmWave) bands in addition to sub-6GHz bands. To keep the complexity and implementation cost
low, hybrid analog-digital beam-forming with large-scale antenna array has become a common design
approach to address the issue of higher propagation loss as well as to improve spectral efficiency in
mmWave communication in 5G NR. The 5G NR standard is designed to adapt to different beam-forming
architecture and deployment scenarios. This paper provides the overview on beam management procedure according to the current 5G standardization progress. We discuss some major challenges of millimeterwave communications encountered in the current 5G NR standard and present some expected enhancements considered for the future beyond-5G standard. |
