Mobile communication via high-altitude platforms operating in the stratosphere is an idea that has been on the table for decades. In the past few years, however, with recent advances in technology and parallel progress in standardization and regulatory bodies like the 3rd Generation Partnership Project (3GPP) and International Telecommunications Union (ITU), these ideas have gained considerable momentum. In this article, we present a comprehensive overview of high-altitude platform stations (HAPS) as international mobile telecommunications (IMT) base stations (BS) (HIBS). We lay out possible use cases and summarize the current status of the development from a technological point of view as well as standardization in 3GPP and regarding spectrum aspects. We then present some system-level simulation results to shed light on the performance of HIBS. We conclude by pointing out several directions for future research.

作为国际移动通信基站的高空平台站：HIBS 入门


通过在平流层运行的高空平台进行移动通信是一个几十年来一直被讨论的想法。然而，在过去几年中，随着技术的最新进步以及第三代合作伙伴计划 (3GPP) 和国际电信联盟 (ITU) 等标准化和监管机构的并行进展，这些想法获得了相当大的发展势头。在本文中，我们全面概述了作为国际移动电信 (IMT) 基站 (BS) (HIBS) 的高空平台站 (HAPS)。我们列出了可能的用例，并从技术角度以及 3GPP 标准化和频谱方面总结了当前的发展状况。然后，我们提供一些系统级仿真结果来阐明 HIBS 的性能。最后，我们指出了未来研究的几个方向。
