论文摘要
作为新兴的空中机器人技术领域，无人驾驶汽车（UAV）在无线网络研究社区中获得了重要的研究兴趣。一旦国家立法允许无人机自动飞行，我们将看到一群无人机填充我们智能城市的天空来完成不同的任务：包裹交付，基础设施监测，活动拍摄，监视，跟踪等。无人机生态系统可以从现有的5G/B5G蜂窝网络中受益，这些网络可以在不同的方式中受益于不同的uavclus剂，从而增强了UAV的uav uav uav uav。由于无人机在3D空间中具有柔性移动性，自动操作和智能放置的固有特征，因此这些智能设备符合广泛的无线应用程序和用例。这项工作旨在对5G/B5G蜂窝系统和无人机技术之间的集成协同作用进行深入探索，在该技术中，无人机被作为新的空中用户设备（UE）集成到现有的蜂窝网络。在此集成中，无人机在蜂窝覆盖范围内扮演飞行用户的角色，因此它们被称为蜂窝连接的无人机（又称无人机，无人机，5G连接的无人机或空中用户）。这项工作的主要重点是对整合挑战以及关键的5G/B5G技术创新以及在设计原型制作和现场试验中的持续努力进行广泛的研究，以证实了与细胞连接的无人机。这项研究强调了有关3GPP标准化的最新进度更新，并强调了在成功采用这项有前途的技术之前必须考虑的社会经济问题。还讨论了铺平未来研究机会的各种开放问题。
As an emerging field of aerial robotics, Unmanned Aerial Vehicles (UAVs) have gained significant research interest within the wireless networking research community. As soon as national legislations allow UAVs to fly autonomously, we will see swarms of UAV populating the sky of our smart cities to accomplish different missions: parcel delivery, infrastructure monitoring, event filming, surveillance, tracking, etc. The UAV ecosystem can benefit from existing 5G/B5G cellular networks, which can be exploited in different ways to enhance UAV communications. Because of the inherent characteristics of UAV pertaining to flexible mobility in 3D space, autonomous operation and intelligent placement, these smart devices cater to wide range of wireless applications and use cases. This work aims at presenting an in-depth exploration of integration synergies between 5G/B5G cellular systems and UAV technology, where the UAV is integrated as a new aerial User Equipment (UE) to existing cellular networks. In this integration, the UAVs perform the role of flying users within cellular coverage, thus they are termed as cellular-connected UAVs (a.k.a. UAV-UE, drone-UE, 5G-connected drone, or aerial user). The main focus of this work is to present an extensive study of integration challenges along with key 5G/B5G technological innovations and ongoing efforts in design prototyping and field trials corroborating cellular-connected UAVs. This study highlights recent progress updates with respect to 3GPP standardization and emphasizes socio-economic concerns that must be accounted before successful adoption of this promising technology. Various open problems paving the path to future research opportunities are also discussed.
