A Tutorial on Beam Management for 3GPP NR at mmWave Frequencies Marco Giordani, Student Member, IEEE, Michele Polese, Student Member, IEEE, Arnab Roy, Member, IEEE, Douglas Castor, Member, IEEE, Michele Zorzi, Fellow, IEEE. Abstract The millimeter wave ( mmWave ) frequencies offer In this context, the millimeter wave ( mmWave ) spectrum . the availability of huge bandwidths to provide unprecedented roughly above 10 GHz1 has been considered as an enabler data rates to next-generation cellular mobile terminals. However, of the 5G performance requirements in micro and picocellular mmWave links are highly susceptible to rapid channel variations [ ] 5 Apr 2018. and suffer from severe free-space pathloss and atmospheric networks [6], [7]. These frequencies offer much more band- absorption. To address these challenges, the base stations and the width than current cellular systems in the congested bands mobile terminals will use highly directional antennas to achieve below 6 GHz, and initial capacity estimates have suggested sufficient link budget in wide area networks.
