摘要
Abstract
Based on the agenda item 1.13 of WRC-19 and requirements for domestic compatibility analysis of the 5th generation (5G) mobile communication candidate frequency bands above 6 GHz,this paper studied the interference from International Mobile Telecommunications 2020 (IMT-2020) system to fixed satellite service (FSS) system in 27-29.5 GHz band.Based on the aggregate interference assessment,the interference from IMT-2020 (5G) base station (BS) to the up-link of FSS receiver where the geostationary orbit satellite at 59 degree,85 degree and 113 degree longitude were comparatively studied.In addition,compatibility simulation under IMT-2020 (5G) base stations with different array configurations is also studied.Study shows that the IMT-2020 (5G) system will not cause harmful interference to fixed satellite services system in the frequency 27.5-29 GHz band,especially in the case of IMT-2020 (5G) base station with large scale antenna array.The results can provide the technology basis for future planning and actual deployment of IMT-2020 (5G) system in 27-29.5 GHz frequency band and protection of FSS.关键词
