Abstract

Remote interference, that the downlink signals from a remote base station (BS) propagate beyond guard period (GP) in the atmospheric duct layer and interfere with the local uplink signals, seriously degrades TDD-based system performance. And remote interference management (RIM) will be standardized in 3rd Generation Partnership Project (3GPP) Release 16. Mitigating the impact of remote BS will be one of the most challenging issues. In this paper, we establish a remote interference simulation system by combining refractivity estimation and parabolic equation (PE) methods. This novel simulation system includes dynamic meteorology measurement design, refractivity estimation, communication setting, and path loss computing. It also provides a traceable approach to remote interference. Moreover we also proved the minimum BS separation distance reference (in 3GPP Release 12) is far from satisfied when atmospheric duct happens. Long-term meteorological statistics and antenna parameters are discussed for mitigating remote interference. The traceable approach can be helpful for RIM and the next generation network deployment planning.

一种新型无线电远程干扰管理的溯源方法

远程干扰是指来自远程基站(BS)的下行信号在大气管道层中传播超过保护周期(GP)并干扰本地上行信号，严重降低了基于tdd的系统性能。远程干扰管理(RIM)将在第三代合作伙伴计划(3GPP)版本16中标准化。减轻远程BS的影响将是最具挑战性的问题之一。本文将折射率估计与抛物方程(PE)方法相结合，建立了一个远程干涉模拟系统。该仿真系统包括动态气象测量设计、折射率估计、通信设置和路径损耗计算。它还为远程干扰提供了一种可跟踪的方法。此外，我们也证明了当大气管道发生时，最小BS分离距离参考(3GPP Release 12)远不能满足。讨论了减少远程干扰的长期气象统计和天线参数。这种可追溯的方法可以帮助RIM和下一代网络部署规划。
