摘要

在超越5G / 6G时代，小卫星LEO星座将在扩展三维(从海洋到天空和空间)通信服务领域的NTN(非地面网络)中发挥重要作用。为了在LEO星座上建立快速稳定的NTN通信基础设施，射频和光通信的混合运行非常重要。作者(Axelspace，东京大学，东京工业大学和KIYOHARA OPTICS)已经在NICT超越5G研发促进项目下开始了为期4年的这些技术开发计划。本文介绍了该研发项目的目标、范围和技术挑战。

RF and Optical Hybrid LEO Communication System for Non-Terrestrial Network

Small satellite LEO constellations are expected to play an important role in NTN (Non-Terrestrial Network) which expands communication service areas in three-dimensions (from sea to sky and space) in the age of Beyond 5G / 6G. To build fast and stable communication infrastructure for NTN over LEO constellations, hybrid operation of RF and optical communications is important. The authors (Axelspace, The University of Tokyo, Tokyo Institute of Technology and KIYOHARA OPTICS) have started 4-year development program on these technologies under NICT Beyond 5G R&D promotion project. In this paper, target, scope and technical challenges of this R&D project are introduced.
