摘要
重点介绍了国际电信联盟最新发布的IMT模型建议书ITU-R M.2101中的阵列天线模型及相关参数,并基于该模型对1.4 GHz的IMT系统下行干扰数字音频广播地球站的场景进行系统级仿真。采用集总干扰评估方法,仿真了不同距离下大规模基站部署对中心地球站的干扰,并通过比较干扰门限得到保护距离。研究结果可为未来IMT系统设计与部署、5G或相关频率规划提供借鉴。
The array antenna model and its parameters in ITU-R REC M.2101 were introduced in detail, and the model would be implemented in IMT deployment scenario modeling. Based on the lumped interference assessment method, the interference of the large-scale base station deployment to the central earth station at different distances was simulated, and the distance was protected by comparing the interference threshold. The research results can provide reference for future IMT system design and deployment, 5G or related frequency planning.
