AI 中文摘要
能耗仍然是当前和未来蜂窝系统的主要运营挑战，尤其是在密集城市部署中。本文研究了非地面网络（NTN）的高空平台站（HAPS）作为节能运营推动者的新角色，而非仅仅是覆盖扩展。我们将HAPS-超级小区定义为一个广域非地面层，它可以承担多个地面宏小区的覆盖任务，首次实现容量和覆盖宏小区的关闭。我们开发了一个符合第三代合作伙伴计划（3GPP）的综合系统模型，以及两种HAPS-超级小区配对架构，以捕捉多层之间的相互作用、实际信道条件和分布式载波关闭（CS）机制。结果表明，HAPS-超级小区可有效降低整体网络功耗。我们还确定了直接集成HAPS的关键限制，为未来优化奠定基础，并为下一代CS运营提供关键见解。
英文摘要
Energy consumption remains a dominant operational challenge for current and future cellular systems, especially in dense urban deployments. This paper investigates a novel role for non terrestrial network (NTN) high-altitude platform station (HAPS) as an enabler of energy-efficient operation rather than only coverage extension. We define the HAPS-Hypercell as a wide-area non-terrestrial layer that can assume the coverage role of multiple terrestrial macro-cells, enabling, for the first time, the shutdown of both capacity and coverage macro-cells. We develop a comprehensive third generation partnership project (3GPP)-compliant system model, along with two HAPS-Hypercell pairing architectures that capture the interplay among multiple layers, realistic channel conditions, and distributed carrier shutdown (CS) mechanisms. Our results show that the HAPS-Hypercell can effectively reduce overall network power consumption. We then identify key limitations of a straightforward HAPS integration, laying the groundwork for future optimization and providing key insights for next-generation CS operations.
