低空无人机(UAV)网络是未来6G集成传感和通信(ISAC)系统的组成部分。 然而,由于无人机的高机动性、复杂的传播环境以及共存的传感和通信功能之间的固有权衡,它们的部署受到了阻碍。 本文提出了一种新的框架,利用可移动天线(MA)和智能反射表面(IRS)作为双重推动因素,以克服这些限制。 MAs通过主动收发器重新配置,IRS通过被动通道重建,可以协同工作,以显着提高系统性能。 我们的分析首先阐述了MA和IRS提供的基本收益,并提供了模拟结果,验证了MA-IRS支持的ISAC架构的巨大潜力。 然后调查两个核心无人机部署场景:(i)无人机作为ISAC用户,我们专注于实现高精度跟踪和空中安全,以及(ii)无人机作为空中网络节点,我们处理稳健的设计和复杂的耦合资源优化。 最后,确定并分析每个场景的关键技术挑战和研究机会,为高级低空ISAC网络的未来设计制定明确的路线。
Low-altitude unmanned aerial vehicle (UAV) networks are integral to future 6G integrated sensing and communication (ISAC) systems. However, their deployment is hindered by challenges stemming from high mobility of UAVs, complex propagation environments, and the inherent trade-offs between coexisting sensing and communication functions. This article proposes a novel framework that leverages movable antennas (MAs) and intelligent reflecting surfaces (IRSs) as dual enablers to overcome these limita...
