摘要:

在过去的几十年里,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不幸地忽略了巨大的地理数字鸿沟,因为高带宽无线覆盖集中在城市地区。为了实现“连接未连接者”的目标,将低地球轨道(LEO)卫星与地面蜂窝网络相结合被广泛认为是一种有前途的解决方案。在本文中,我们首先介绍了低轨卫星星座(SatCons)的发展路线图,包括在低轨卫星与新兴的低轨星座的早期尝试。此外,我们还讨论了采用LEO SatCons提供集成5G网络的独特机会。具体来说,我们提出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与典型的5G用例集成的潜在影响,我们在其中雕刻了我们对LEO SatCons重塑的各种垂直领域的愿景。最后提出了技术挑战,指明了未来的研究方向。

英文摘要:

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, since high bandwidth wireless coverage is concentrated to 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 satellite 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.
