摘要

为了解决IMT系统在覆盖、容量、性能等方面的高要求带来的频谱缺口问题,WRC-19 1.13议题正在着力为未来移动通信系统的发展寻求新的频率划分,其中24.25 GHz—27.5 GHz是主流IMT毫米波候选频段中最低的一段。IMT系统获取频段划分,需解决IMT系统对卫星星间业务的共存干扰问题。通过对互不产生有害干扰的25.25 GHz—27.5 GHz频段IMT-2020(5G)与ISS之间的共存开展研究,分析了二者的兼容共存性能。通过仿真实验证实了二者可以共存。
        In order to compensate the spectrum shortage caused by the high requirements of coverage, capacity and performance in the IMT system, WRC-19 1.13 has focusing on the new frequency division for the development of future mobile communication systems. Therein, the 24.25 GHz—27.5 GHz band is the lowest band in the candidate bands of mainstream IMT millimeter waves. The frequency division of IMT system is dependent on the solution to the interference coexistence between the IMT system and the Inter Satellite Service(ISS). The interference coexistence between the IMT-2020(5 G) at the 25.25 GHz—27.5 GHz band and the ISS is studied. Then, the compatibility and the coexistence performance are analyzed. Simulation experiments validate that they can coexist.
