新型5G网络组件对23.8 GHz带外发射的影响

Impact of new 5G network components on out-of-band emissions at 23.8 GHz

AI总结:

本文分析5G直放站和高功率UE在24 GHz频段部署后对23.8 GHz EESS微波探测仪的潜在显著干扰,并审视ITU现有监管建模方法的适应性。

摘要:

在国际电信联盟(ITU)为2019年世界无线电通信大会(WRC-19)制定发射建议所做的准备工作中,工作于24.25–27.5 GHz的5G网络对用于测量大气水汽和温度的地球探测卫星业务(EESS)微波探测仪的影响曾得到广泛讨论和建模。此后,两类新型网络设备——5G直放站以及用于固定无线业务的高发射功率用户设备(UE)——已被引入并部署于28 GHz网络,预计它们也将部署于24 GHz。本文讨论了这些新组件所导致的(可能显著的)干扰增加,以及与其监管地位相关的未决问题。尽管本文讨论的是“24 GHz”频段内5G传输对23.8 GHz EESS测量的干扰增加,但必须认识到,在对所有频段的5G/6G网络干扰进行建模时,都需要考虑直放站和高功率UE。本文还探讨了ITU当前监管无源传感器干扰的流程和方法(即设备厂商基于长期网络预测和最坏情形Monte Carlo建模而采用的硬件滤波)能否跟上快速变化的无线技术以及日益激烈的频谱竞争。

英文摘要:

The impact of 5G networks transmitting between 24.25- 27.5 GHz on Earth Exploration Satellite Services (EESS) microwave sounders used to measure atmospheric water vapor and temperature was widely discussed and modeled in preparation for setting emission recommendations by International Telecommunications Union (ITU) at the 2019 World Radio Congress (WRC-19). Since then, two new classes of network devices - 5G repeaters and high transmission power User Equipment (UE) for fixed wireless services - have been introduced and deployed in 28 GHz networks with expectations that they will also be deployed at 24 GHz. This paper discusses the (potentially significant) increase in interference from these new components along with open questions related to their regulatory status. While this paper discusses increases in interference to 23.8 GHz EESS measurements from 5G transmissions in the "24 GHz" band, it is important to recognize that repeaters and high power UEs need to be considered when modeling interference from 5G/6G networks in all bands. This paper also touches on whether the current ITU process and methodology to regulate interference with passive sensors (vendor applied hardware-based filtering based on long-term network forecasts and worst-case Monte Carlo modeling) can keep up with rapidly changing wireless technology and the increased competition for spectrum.
