What will the future of UAV cellular communications be? In this tutorial
article, we address such a compelling yet difficult question by embarking on a
journey from 5G to 6G and sharing a large number of realistic case studies
supported by original results. We start by overviewing the status quo on UAV
communications from an industrial standpoint, providing fresh updates from the
3GPP and detailing new 5G NR features in support of aerial devices. We then
show the potential and the limitations of such features. In particular, we
demonstrate how sub-6 GHz massive MIMO can successfully tackle cell selection
and interference challenges, we showcase encouraging mmWave coverage
evaluations in both urban and suburban/rural settings, and we examine the
peculiarities of direct device-to-device communications in the sky. Moving on,
we sneak a peek at next-generation UAV communications, listing some of the use
cases envisioned for the 2030s. We identify the most promising 6G enablers for
UAV communication, those expected to take the performance and reliability to
the next level. For each of these disruptive new paradigms (non-terrestrial
networks, cell-free architectures, artificial intelligence, reconfigurable
intelligent surfaces, and THz communications), we gauge the prospective
benefits for UAVs and discuss the main technological hurdles that stand in the
way. All along, we distil our numerous findings into essential takeaways, and
we identify key open problems worthy of further study.
