摘　　要：根据国际电信联盟(International Telecommunication Union,ITU)的相关建议和报告以及技术特性,提出了一种用于分析26GHz频段IMT-2020(5G)系统与卫星间业务(Inter-Satellite Service,ISS)兼容共存性的方法.方法将全球较大面积部署的国际移动通信系统(International Mobile Telecommunications,IMT)基站合理地建模为一定数量的中心站,从时间和空间两个维度开展分析.其中,时间分析以全球范围的IMT-2020(5G)基站为对象;空间分析以中国大陆范围的IMT-2020(5G)基站为对象,还考虑了实际的城市人口数量.分析结果表明,在26GHz频段部署IMT系统,与卫星间业务具有兼容共存的空间.The paper develops a methodology for analyzing the compatibility of International Mobile Telecommunications 2020 （IMT-2020） and inter-satellite services （ISS） in the 26 GHz band, based on relevant ITU recommendations and reports, and current technical characteristics of both systems. It is proposed to model the massive IMT-2020 （5G） base stations around the world into a set of central base stations, and to analyze the temporal and spatial characteristics of interference from 5G base stations to ISS. Based on the IMT-2020 （5G） base stations in China's Mainland, the spatial characteristics of the interference to ISS are analyzed. The actual population is also taken into account in the calculation of aggregate interference of IMT-2020. The results show that these two systems have considerable possibilities in coexistence in the 26 GHz frequency band.
