卫星通信具有覆盖大面积地理区域的潜力。这种无所不在的特性为目前无人服务的偏远地区以及飞机和船舶等移动平台提供了连接的潜力。然而，许多卫星系统是在专用网络上开发的，每个卫星系统和最终用户设备（UE）都有各自的解决方案。为了将卫星行业标准扩展到全球电信标准，第三代合作伙伴计划（3GPP）目前正在开展活动，研究第五代（5G）新无线电（NR） 3GPP标准的可行性和所需的标准适配。在本文中，我们概述了3GPP RAN工作组正在进行的活动，重点关注RAN2和RAN3方面，以实现地球同步轨道（GEO）和非GEO卫星系统上的NR通信。
Satellite communication has the potential to provide coverage over large geographical areas. This ubiquity enables potential for providing connectivity for currently unserved remote areas as well as for moving platforms such as airplanes and ships. However, many satellite systems were developed on private networks, each having their individual solution for the satellite systems and for the end user equipment (UE). In order to extent the satellite-industry-wide standards to global telecommunication standards, there are currently activities in the 3rd generation partnership project (3GPP) to study the feasibility and needed standard adaptations for the 5th generation (5G) new radio (NR) 3GPP standard. In this paper, we provide an overview of the ongoing activity in 3GPP RAN working groups with focus on RAN2 and RAN3 aspects for enabling NR communication over geosynchronous orbit (GEO) and non-GEO satellite systems.
