摘要
首先,根据5G和卫星通信融合的发展现状和趋势,指出了开展星地融合空口传输技术研究的必要性;然后,结合国际标准化组织3GPP非地面网络(Non-Terrestrial Networks,NTN)的研究,提炼了基于5G的星地融合空口传输的关键技术,并给出了潜在的解决方案;最后,面向未来天地一体化星地深度融合发展,探讨了基于可变参数集的统一空口设计思路,为后续相关标准研究提供参考。
With analysis of the integration of the satellite communications and the 5G system,the necessity of the integrated design of the radio air-interface technologies was pointed out firstly.Then,based on the research of NTN in 3GPP,key technologies of the radio air-interface for the integrated satellite-terrestrial system were refined,and potential solutions were proposed.Finally,for the future development of satellite-terrestrial integration,the unified radio airinterface design idea based on variable parameter set was discussed,which will provide guidance for future NTN projects in 3GPP standardization.
