AI 中文摘要
虽然低地球轨道(LEO)卫星是6G覆盖扩展的关键推动因素,但高空平台站(HAPS)在延迟、足迹持久性和部署灵活性方面提供了互补优势。我们将BLASTER流量感知资源管理框架[1]扩展,以联合优化用户关联、带宽分配和功率控制,涵盖单个LEO平台(600公里)以及1、4和9个平台(20公里)的HAPS部署,并采用层内频率复用,在完整的昼夜流量剖面下进行评估。增加HAPS数量持续改善覆盖、信干噪比(SINR)、总对数吞吐量和地面能源节省;9-HAPS部署达到LEO级别的服务质量(QoS),同时所需活跃地面基站数量大幅减少。这些结果将多HAPS架构定位为6G非地面网络(NTN)中LEO的引人注目的节能替代方案。
英文摘要
While low Earth orbit (LEO) satellites are a key enabler for 6G coverage extension, high-altitude platform stations (HAPS) offer complementary advantages in latency, footprint persistence, and deployment flexibility. We extend the BLASTER traffic-aware resource management framework [1] to jointly optimize user association, bandwidth splitting, and power control across a single LEO platform (600 km) and HAPS deployments of 1, 4, and 9 platforms (20 km) with intra-tier frequency reuse, evaluated over a full diurnal traffic profile. Increasing the HAPS count consistently improves coverage, SINR, sum-log throughput, and terrestrial energy savings; a 9-HAPS deployment matches LEO-level QoS while requiring substantially fewer active terrestrial base stations. These results position multi-HAPS architectures as a compelling, energy-efficient alternative to LEO for 6G non-terrestrial networks (NTNs).
