摘要

为扩大 5G 通信部署而对 3.7-4.0 GHz 频段进行的改革会带来 5G 信号干扰雷达高度计工作的风险,导致数据丢失或不准确。因此,本文提出了一种护带保护方法,以促进在 4.2-4.4 GHz 频段工作的 5G 基站和雷达高度计的共存。为了提高相邻信道泄漏比(ACLR),我们使用高功率放大器模型在过采样波形上实现了频谱再生,过滤了带外频谱发射。结果表明,除农村环境中 16×16 天线阵列的情况外,150 MHz 的保护带可实现共存。值得注意的是,对于城市环境中的 4×4 天线阵列,使用 50 MHz 的保护带可实现共存。拟议的缓解技术还可扩展到促进非地面网络与 5G 通信系统之间的共存,包括卫星、无人驾驶飞行器和热气球。

Guard Band Protection Scheme to Facilitate Coexistence of 5G Base Stations and Radar Altimeters
Reformation of the 3.7–4.0 GHz band to expand 5G communication deployment poses a risk of 5G signals disrupting radar altimeter operation, leading to data loss or inaccuracies. Thus, this paper proposes a guard band protection method to facilitate the coexistence of 5G base stations and radar altimeters operating in the 4.2–4.4 GHz band. To enhance the adjacent channel leakage ratio (ACLR), we implemented spectral regrowth on an oversampled waveform using a high-power amplifier model, filtering out-of-band spectral emissions. The results demonstrated that a 150 MHz guard band enables coexistence, except in the case of the 16-by-16 antenna array in rural environments. Notably, for the 4-by-4 antenna array in urban environments, coexistence can be achieved using a 50 MHz guard band. The proposed mitigation techniques may also be extended to promote coexistence between non-terrestrial networks and 5G communication systems, including satellites, unmanned aerial vehicles, and hot air balloons.
