论文摘要
反射智能表面（RISS）的高配置性和低成本使它们成为增强超越第五代（B5G）网络能力的有前途的解决方案。最近的作品提议将Riss骑上无人机（UAV）（UAVS），将RIS提供的高网络配置性与无人机带来的移动性相结合。但是，RI代表了影响无人机电池寿命的额外重量。此外，尚未详细评估所得链接的实用性。在本文中，我们重点介绍了所有需要考虑RIS启用无人机的基本功能。我们是第一个展示RIS尺寸及其功耗如何影响无人机飞行时间的人。然后，我们评估RIS大小，载体频率和无人机飞行高度如何影响路径损失。最后，我们提出了一种基于粒子群的新方法，以最大程度地提高覆盖范围并在蜂窝情况下提高传输的机密性，并在无人机携带的RISS的支持下。
The high configurability and low cost of Reflective Intelligent Surfaces (RISs) made them a promising solution for enhancing the capabilities of Beyond Fifth-Generation (B5G) networks. Recent works proposed to mount RISs on Unmanned Aerial Vehicles (UAVs), combining the high network configurability provided by RIS with the mobility brought by UAVs. However, the RIS represents an additional weight that impacts the battery lifetime of the UAV. Furthermore, the practicality of the resulting link in terms of communication channel quality and security have not been assessed in detail. In this paper, we highlight all the essential features that need to be considered for the practical deployment of RIS-enabled UAVs. We are the first to show how the RIS size and its power consumption impact the UAV flight time. We then assess how the RIS size, carrier frequency, and UAV flying altitude affects the path loss. Lastly, we propose a novel particle swarm-based approach to maximize coverage and improve the confidentiality of transmissions in a cellular scenario with the support of RISs carried by UAVs.
