摘要

本文通过分析IMT-2020与固定卫星业务(FSS)上行链路在27-27.5 GHz频段的干扰潜力，探讨了两种业务频谱共存的可能性。我们参考最新的ITU-R文件对受害接收机的干扰功率进行建模和计算，并将其与受害接收机的保护标准进行比较。此外，采用具有纬度/经度/海拔坐标的三维地形数据，对全球范围内大量地面IMT-2020系统聚合的干扰功率进行精确建模。结果表明，FSS空间站对IMT-2020聚合干扰具有较强的安全性，基站和用户设备分别位于距FSS地球站3.3 km和0.9 km的位置时，可有效保护IMT-2020业务。

Spectral Coexistence of IMT-2020 with Fixed-Satellite Service in the 27-27.5 GHz Band

In this paper, we investigate the possibility of spectral coexistence of the two services through the analysis of interference potential between IMT-2020 and fixed-satellite service (FSS) uplink in the 27-27.5 GHz frequency band. We model and calculate the interference power at victim receivers referring to up-to-date ITU-R documents and compare them with the protection criteria of the victim receivers. Furthermore, three-dimensional (3D) topographic data with latitude/longitude/altitude coordinates are adopted to exactly model the interference power aggregated from a large number of terrestrial IMT-2020 systems in worldwide areas. The results show that the FSS space station is safe from the aggregated IMT-2020 interference, and the IMT-2020 service can be protected when base station (BS) and user equipment (UE) are located 3.3 and 0.9 km away from the FSS earth station.
