This paper studies the effect of the co-existence between fifth-generation (5G) millimeter-wave wireless systems and fixed services (FS) in the 28-GHz band (which suffers from 5G adjacent channel interference). 5G is expected to share spectrum with FSs in high-frequency ranges. This paper compares the alpha-beta-gamma (ABG) model and the path loss of the close-in (PLCI) model used in millimeter waves, to designing 5G systems in urban macro-cell scenarios. This study aims to illustrate different approaches to reducing the interference that 5G networks cause over FS. The contribution of this paper is to determine the interference-level network parameters, such as beamforming, varying the antenna height of the FS receiver, and the angle between the 5G base station (BS) and the FS antenna, using realistic large-scale path loss models.

摘要

This paper studies the effect of the co-existence between fifth-generation (5G) millimeter-wave wireless systems and fixed services (FS) in the 28-GHz band (which suffers from 5G adjacent channel interference). 5G is expected to share spectrum with FSs in high-frequency ranges. This paper compares the alpha-beta-gamma (ABG) model and the path loss of the close-in (PLCI) model used in millimeter waves, to designing 5G systems in urban macro-cell scenarios. This study aims to illustrate different approaches to reducing the interference that 5G networks cause over FS. The contribution of this paper is to determine the interference-level network parameters, such as beamforming, varying the antenna height of the FS receiver, and the angle between the 5G base station (BS) and the FS antenna, using realistic large-scale path loss models.
