AI 中文摘要
高空平台站（HAPS）是6G及后续网络中极具前景的组成部分，天线阵列配置对于利用大规模MIMO实现广域覆盖和高容量至关重要。本文在用户设备（UE）服从均匀分布、高斯分布和泊松簇过程分布的条件下，研究并比较了五种天线阵列结构下用户设备的上行链路信干噪比（SINR）分布，这五种结构包括圆柱形天线阵列、3GPP天线阵列、半球形天线阵列，以及两种提出的架构：截锥形天线阵列和截半球形天线阵列。仿真结果表明，两种提出的阵列均能达到与半球形阵列相当的性能，其中截半球形阵列对密集分布的UE特别有效，而截锥形阵列在性能与实现复杂度之间提供了良好的权衡。
英文摘要
High-altitude platform stations (HAPS) are promising components of 6G and beyond networks, where antenna array configuration is critical for achieving wide-area coverage and high capacity with massive MIMO. This paper investigates and compares the uplink signal-to-interference-plus-noise ratio (SINR) distributions of user equipments (UEs) for five antenna array structures, including the cylindrical antenna array, the 3GPP antenna array, the hemispherical antenna array, and two proposed architectures, namely the truncated cone and truncated hemispherical antenna arrays, under uniform, Gaussian, and Poisson cluster process UEs distributions. Simulation results show that both proposed arrays achieve performance comparable to the hemispherical array, with the truncated hemispherical array being particularly effective for densely distributed UEs, while the truncated cone array offers a favorable tradeoff between performance and implementation complexity.
