摘　　要：基于现有技术参数,研究了25.25~27.5 GHz频段国际移动通信（IMT）系统与卫星间业务数据中继卫星（DRS）系统间的干扰共存情况。采用集总干扰评估方法,比较了数据中继卫星经度分别在59°、85°、113°时,IMT基站对其造成干扰的情况。此外,还通过固定干扰余量,推导了IMT基站总数及其与IMT发射功率之间的关系。研究结果可为未来25.25~27.5 GHz频段IMT系统设计与部署、5G频率规划提供借鉴。Based on the existing technical parameters, the interference coexistence of 25.25 ~27.5 GHz band international mobile communication（IMT） system and inter-satellite service data relay satellite（DRS） were studied.Based on the aggregate interference assessment, the interference between IMT base station（BS） and inter-satellite service DRS receiver where the DRS orbit at 59 degree, 85 degree and 113 degree longitude were comparatively studied. In addition, the tradeoff between the total number of IMT BS and its transmission power was analyzed with certain interference margin. These results are useful for designing and deployment of IMT systems in 25.25~27.5 GHz band 5G spectrum planning in the future.
