Abstract: 
To support the ubiquitous connectivity requirement of sixth generation communication, unmanned aerial vehicles (UAVs) play a key role as a major part of the future communication networks. One major issue in UAV communications is the interference resulting from spectrum sharing and line-of-sight links. Recently, the application of the coordinated multipoint (CoMP) technology has been proposed to reduce the interference in the UAV-terrestrial heterogeneous network (HetNet). In this paper, we consider a three-dimensional (3D) multilayer UAV-terrestrial HetNet, where the aerial base stations (ABSs) are deployed at multiple different altitudes. Using stochastic geometry, we develop a tractable mathematical framework to characterize the aggregate interference and evaluate the coverage probability of this HetNet. Our numerical results show that the implementation of the CoMP scheme can effectively reduce the interference in the network, especially when the density of base stations is relatively large. Furthermore, the system parameters of the ABSs deployed at higher altitudes dominantly influence the coverage performance of the considered 3D HetNet.

摘要:为满足第六代移动通信的泛在连接需求,无人机作为未来通信网络主要组成部分发挥着关键作用。频谱共享和视距链路传输造成的干扰是无人机通信的一个主要问题。近年来,为减少无人机--地面异构网络干扰,提出多点协同传输技术。本文提出一个三维多层无人机-地面异构网络,其中无人机作为空中基站部署于不同高度。利用随机几何理论,提出一个易于处理的数学框架评估这个异构网络的干扰统计特性和覆盖概率。数值结果表明多点协同传输机制能有效缓解网络中的干扰,尤其当基站密度较大时。此外,部署在更高的空中基站的系统参数是影响所提三维异构网络覆盖性能的主要因素。
