AI 中文摘要
高空平台(HAP)是下一代非地面网络(NTN)的关键使能技术,具备覆盖范围广、续航时间长、部署迅速等优势。然而,当前非地面网络设计仍以卫星为中心,依赖地面蜂窝网络的假设,限制了灵活性与可扩展性。为克服这些局限,本文提出一种以HAP为中心的多层自组织空中网络(FANET)。该框架中,HAP与分布式无人机(UAV)集成,形成可自主运行的独立无蜂窝(CF)非地面系统。分层架构包含HAP间自组织层、HAP与UAV协作层、UAV到地面接入层,共同实现空中连通、自适应覆盖及感知干扰的用户接入。分析了各层的独特挑战,包括HAP间连通性、FANET与地面网络(TN)共存、异构条件下的用户接入。此外,本文引入关键策略,如用于高数据速率连通的快速波束对齐、非协调FANET/TN共存、用户定位与环境分类。通过三个案例研究验证,还概述了标准化路径。结果表明,以HAP为中心的FANET是构建弹性、可扩展、面向应用的6G非地面网络部署的基础。
英文摘要
High-altitude platforms (HAPs) are key enablers of next-generation non-terrestrial networks (NTNs), offering wide coverage, long endurance, and rapid deployment. Despite these advantages, current NTN designs remain satellite-centric and rely on terrestrial cellular assumptions, limiting flexibility and scalability. To overcome these limitations, this article proposes a multi-layer HAP-centric flying ad-hoc network (FANET). In this framework, HAPs are integrated with distributed uncrewed aerial vehicles (UAVs) to form a standalone, cell-free (CF) non-terrestrial system capable of autonomous operation. The layered architecture consists of an inter-HAP ad-hoc layer, a HAP-to-UAV cooperative layer, and a UAV-to-ground access layer, collectively enabling aerial connectivity, adaptive coverage, and interference-aware user access. Unique challenges for each layer are analyzed, including inter-HAP connectivity, FANET co-existence with terrestrial networks (TNs), and user access under heterogeneous conditions. Moreover, the article introduces enabling strategies such as fast beam alignment for high data rate connectivity, uncoordinated FANET/TN co-existence, and user localization and environment classification. Validated by three case studies, the discussion also outlines standardization pathways. The results highlight HAP-centric FANETs as a foundation for resilient, scalable, and application-oriented 6G NTN deployments.
