实现无人机与其相关地面飞行员/用户之间的高速率、低延迟和超可靠的无线通信对于实现其未来的大规模使用至关重要。为了实现这一目标，蜂窝连接无人机是一项很有前途的技术，它将各种应用的无人机作为新的空中用户集成到蜂窝网络中，最近引起了极大的关注。与地面用户的传统蜂窝通信相比，蜂窝连接的无人机通信具有本质上的不同特点，这给研究带来了新的挑战和机遇。在本文中，我们首先讨论这项新兴技术的潜在优势、独特的通信和频谱要求以及新的设计考虑因素，从而概述这项新兴技术。然后，我们介绍了有前景的技术，以支持未来一代3D异质无线网络，使空中和地面用户共存。最后，我们给出了仿真结果，验证了我们的讨论，并强调了未来研究的重点方向。
Enabling high-rate, low-latency and ultra-reliable wireless communications between UAVs and their associated ground pilots/users is of paramount importance to realize their large-scale usage in the future. To achieve this goal, cellular- connected UAV, whereby UAVs for various applications are integrated into the cellular network as new aerial users, is a promising technology that has drawn significant attention recently. Compared to conventional cellular communication with terrestrial users, cellular-connected UAV communication possesses substantially different characteristics that present new research challenges as well as opportunities. In this article, we provide an overview of this emerging technology, by first discussing its potential benefits, unique communication and spectrum requirements, as well as new design considerations. We then introduce promising technologies to enable the future generation of 3D heterogeneous wireless networks with coexisting aerial and ground users. Last, we present simulation results to corroborate our discussions and highlight key directions for future research.
