摘要
随着新兴宽带卫星通信星座的发展,卫星通信与5G通信的融合成为当前发展的热点。梳理当前卫星5G发展的现状,重点介绍3GPP、ITU、Sat5G等标准化组织的工作成果。在此基础上提出卫星5G网络总体架构,介绍卫星动态拓扑条件下的组网、多频段星地一体化波形设计、卫星物联网用户多址接入、无线资源管理和干扰协调等技术研究和发展情况,并探索OTFS、非正交多址接入以及基于频谱感知的NGSO和GSO干扰协调等新技术的可行性;最后对6G阶段天地融合网络的发展进行展望。
With the development of new broadband satellite communication constellation,the fusion of satellite communication and 5G has become a hot spot in the communication industry.The current status of the development of satellite 5G was summarized,and the work achievements of 3GPP,ITU,SaT5G and other international standard development organizations were introduced.On the basis,the overall architecture of satellite 5G network was proposed,the research and development were introduced such as networking under the condition of satellite dynamic topology,multi band satellite ground integration waveform design,multiple access to satellite IoT terminal,radio resource management and interference coordination.In addition,the feasibility of new technologies such as OTFS,non-orthogonal multiple access and interference coordination of NGSO and GSO based on spectrum sensing were explored.Finally,the development of the 6G phase of integrated satellite and terrestrial networks was presented.
