摘要

随着泛在宽带通信需求的日益增长和天地一体化通信技术的持续演进，卫星通信与地面移动通信网络从各自独立发展正逐步走向深度融合。重点面向星地融合领域介绍了星地频率共享关键技术。首先，阐述了星地融合频率共享系统的干扰类型及兼容性分析方法；其次，提出了面向星地频率共享的智能协作接入网架构。基于此架构，设计了波位级星地频率动态共享方案。为后续业界星地融合网络频率共享技术研究提供参考和借鉴。

Abstract

With the increasing demand for ubiquitous broadband communication and the continuous evolution of space-terrestrial integrated communication technology

satellite communication and terrestrial mobile communication networks have gradually shifted from independent development to deep integration. The key technologies of satellite-terrestrial spectrum sharing in the field of satellite-terrestrial integration were introduced. Firstly

the typical scenarios of the satellite-terrestrial spectrum sharing system and the compatibility analysis method were elaborated. Secondly

an intelligent cooperative access network architecture for satellite-terrestrial spectrum sharing was put forward. Based on this architecture

a beam-position-level satellite-terrestrial dynamic spectrum sharing scheme was proposed. References and insights are provided for the subsequent research on the spectrum sharing technology of the satellite-terrestrial integrated network in the industry.
