Abstract

This paper investigates multi-point transmission schemes for Urban Air Mobility (UAM) within the framework of Integrated Satellite and Terrestrial Networks (ISTN). While existing studies have focused on independent connections between terrestrial and satellite networks, this work is the first to explore multi-point transmission specifically for UAM in aerial environments. Based on this investigation, we propose a novel leakage based multi-point transmission scheme that adaptively applies dynamic point selection and joint transmission based on sector leakage levels to mitigate interference and enhance low-SINR UAM unit performance. System-level simulation results demonstrate that the proposed scheme achieves 12.65% reliability improvement compared to dynamic point selection and 6.1% enhancement compared to joint transmission.

基于泄漏的星地一体网UAM多点传输

本文研究了星地一体化网络（ISTN）框架下城市空中交通（UAM）的多点传输方案。虽然现有的研究主要集中在地面和卫星网络之间的独立连接，但这项工作是第一次探索空中环境中UAM的多点传输。在此基础上，我们提出了一种基于泄漏的多点传输方案，该方案基于扇区泄漏水平自适应地采用动态点选择和联合传输，以减轻干扰并提高低信噪比UAM机组的性能。系统级仿真结果表明，该方案比动态选点方案可靠性提高12.65%，比联合传输方案可靠性提高6.1%。
