The rapid development of communication technologies in the past decades has provided immense vertical opportunities for individuals and enterprises. However, conventional terrestrial cellular networks have unfortunately neglected the huge geographical digital divide, ^s ince high-bandwidth wireless coverage is concentrated in urban areas. To meet the goal of “connecting the unconnected,” integrating low Earth orbit (LEO) satellites with the terrestrial cellular networks has been widely considered as a promising solution. In this article, we first introduce the development roadmap of LEO ^sa tellite constellations (SatCons), including early attempts in LEO satellites with the emerging LEO constellations. Further, we discuss the unique opportunities of employing LEO SatCons for the delivery of integrating 5G networks. Specifically, we present their key performance indicators, which offer important guidelines for the design of associated enabling techniques, and then discuss the potential impact of integrating LEO SatCons with typical 5G use cases, where we engrave our vision of various vertical domains reshaped by LEO SatCons. Technical challenges are finally provided to specify future research directions.

5G 及以后的 LEO 卫星星座：它们将如何重塑垂直领域？

过去几十年通信技术的快速发展为个人和企业提供了巨大的垂直机会。然而，传统的地面蜂窝网络已经不幸被忽视的巨大地理数字鸿沟，^Ş 因斯高带宽的无线覆盖集中在城市地区。为了实现“连接未连接”的目标，将低地球轨道 (LEO) 卫星与地面蜂窝网络集成已被广泛认为是一种很有前景的解决方案。在本文中，我们首先介绍LEO ^sa的发展路线图 卫星星座 (SatCons)，包括使用新兴的 LEO 星座在 LEO 卫星上的早期尝试。此外，我们讨论了采用 LEO SatCon 来交付集成 5G 网络的独特机会。具体来说，我们介绍了他们的关键性能指标，为相关使能技术的设计提供了重要的指导方针，然后讨论了将 LEO SatCons 与典型 5G 用例集成的潜在影响，在那里我们雕刻了我们对 LEO SatCons 重塑的各种垂直领域的愿景. 最后提供了技术挑战来指定未来的研究方向。
