Understanding UAV Cellular Communications: From Existing Networks to Massive MIMO

Abstract: The purpose of this article is to bestow the reader with a timely study of UAV cellular communications, bridging the gap between the 3GPP standardization status quo and the more forward-looking research. Special emphasis is placed on the downlink command and control (C&C) channel to aerial users, whose reliability is deemed of paramount technological importance for the commercial success of UAV cellular communications. Through a realistic side-by-side comparison of two network deployments -a present-day cellul… Show more

“…In this scenario, the role of UAV can be either terminal UE served by static BSs or flying relays that forward files to other UEs, aiming at alleviating the peak backhaul traffic and assisting the SBSs. Recent works [20], [21] and [24] have extended conventional terrestrial cellular services to aerial users in the 5G networks. In addition, the 3GPP launched an investigation on enhanced LTE support for aerial users in 2017 and proposed a channel model for aerial UEs [25].…”

“…We assume that the SBSs, the TUs and the UAVs are deployed according to three independent HPPPs with the height of h BS , h TU and h AU , respectively. With reference to [5] and [24], consider that all the UAVs are positioned at the same height 1 . Let λ s be the density of SBSs, λ TU be the density of TUs, and λ AU be the density of UAVs.…”
