本文综述了流体天线辅助非地面网络（FA-NTN）的基础原理、联合优化方案、物理层安全及未来方向，旨在通过可重构天线提升信道分集和复用增益，解决动态传播、能量约束和干扰等挑战。

摘要：

随着第六代（6G）网络对超可靠、低延迟和泛在连接的需求激增，非地面网络（NTN）通过提供灵活接入和全球覆盖，成为地面网络的关键补充。尽管潜力巨大，NTN仍面临动态传播环境、能量约束和密集干扰等关键挑战。作为一项关键的6G技术，流体天线（FA）可通过在有限空间内重新配置辐射元件（如位置和旋转）来重塑无线信道，提供更高的信道分集和复用增益。与固定位置天线相比，FA为NTN提供了一条有前景的集成路径，以缓解动态信道衰落并优化资源分配。本文对FA辅助NTN进行了全面综述。我们首先简要概述了现有NTN的经典结构和局限性、FA的基础知识和优势，以及FA辅助NTN的基本原理。然后，我们研究了联合优化解决方案，详细介绍了FA配置、NTN平台运动模式和资源分配的调整。我们还讨论了与其他新兴技术的结合，并探索了FA辅助NTN作为一种用于智能功能集成的新型网络架构。此外，我们深入探讨了FA辅助NTN中的物理层安全和隐蔽通信。最后，我们指出了潜在未来方向，以赋能FA辅助NTN的更广泛应用。

英文摘要：

With the surging demand for ultra-reliable, low-latency, and ubiquitous connectivity in Sixth-Generation (6G) networks, Non-Terrestrial Networks (NTNs) emerge as a key complement to terrestrial networks by offering flexible access and global coverage. Despite the significant potential, NTNs still face critical challenges, including dynamic propagation environments, energy constraints, and dense interference. As a key 6G technology, Fluid Antennas (FAs) can reshape wireless channels by reconfiguring radiating elements within a limited space, such as their positions and rotations, to provide higher channel diversity and multiplexing gains. Compared to fixed-position antennas, FAs can present a promising integration path for NTNs to mitigate dynamic channel fading and optimize resource allocation. This paper provides a comprehensive review of FA-assisted NTNs. We begin with a brief overview of the classical structure and limitations of existing NTNs, the fundamentals and advantages of FAs, and the basic principles of FA-assisted NTNs. We then investigate the joint optimization solutions, detailing the adjustments of FA configurations, NTN platform motion modes, and resource allocations. We also discuss the combination with other emerging technologies and explore FA-assisted NTNs as a novel network architecture for intelligent function integrations. Furthermore, we delve into the physical layer security and covert communication in FA-assisted NTNs. Finally, we highlight the potential future directions to empower broader applications of FA-assisted NTNs.
