摘要:
本文提出了一种新的空中回传架构,采用空中主动可重构智能表面(RIS)以实现高效能、全3D覆盖,包括无人机基站和地面用户。不同于以往仅限于2D覆盖且仅服务地面用户的空中RIS方法,所提出的设计将主动RIS安装在高空平台上,能够实现可靠的视距链路并通过放大克服乘性衰减。在无人机基站部署以应对城市突发交通高峰的场景中,空中主动RIS既能反射又能放大回传信号以克服阻挡。我们联合优化空中平台位置、阵列划分和RIS相位配置以最大化无人机基站的能量效率。仿真结果证实,所提方法显著优于基准方法,证明其在6G网络中提供可靠回传连接和全面3D覆盖的强潜力。
英文摘要:
In this paper, we propose a novel aerial backhaul architecture that employs an aerial active reconfigurable intelligent surface (RIS) to achieve energy-efficient, {full 3D coverage including UAV-BSs and ground users in 6G wireless networks}. Unlike prior aerial-RIS approaches limited to {2D coverage with only servicing ground users} or passive operation, the proposed design integrates an active-RIS onto a high-altitude aerial platform, enabling reliable line-of-sight links and overcoming multiplicative fading through amplification. In a scenario with UAV-BSs deployed to handle sudden traffic surges in urban areas, the aerial-active-RIS both reflects and amplifies backhaul signals to overcome blockage. We jointly optimize the aerial platform placement, array partitioning, and RIS phase configuration to maximize UAV-BS energy-efficiency. Simulation results confirm that the proposed method significantly outperforms benchmarks, demonstrating its strong potential to deliver resilient backhaul connectivity with comprehensive 3D coverage in 6G networks.
