Abstract
Different from a terrestrial network, novel un-manned aerial vehicle (UAV) networks are necessary to efficiently serve aerial users (AUs) as well as ground users (GUs). In this paper, we model a base station (BS) antenna power gain, which is determined by the BS antenna tilt angle and the horizontal distance between BS and user (GU or AU). In order to efficiently serve both GUs and AUs, we propose two BS service schemes, inclusive-service base station (IS-BS) and exclusiveservice base station (ES-BS) schemes. For each BS service scheme, we derive a network outage probability by taking into account the characteristics of the BS antenna power gain and channel components for line-of-sight (LoS) and non-line-of-sight (NLoS) environments. Finally, we show that the effect of the total BS density, the interfering BS density, and the user density on the optimal BS tilt angle and our proposed scheme.
