SVM-Based Automatic Dynamic Setback Method for Spectrum Sharing in the Adjustment Areas of Private 5G Networks

Recently, private 5G networks, designed to meet the needs of specific regions or zones as required by enterprises across various industrial sectors, have garnered significant attention. However, the current approach to defining private 5G network usage zones involves demarcating areas based on buildings, land, and other zones. This can result in interference between adjacent private 5G networks operating in the same frequency band in a real radio environment. In this paper, we propose a method for defining usage zones that includes the establishment of an adjustment area using SVM within the overlapping coverage areas of adjacent private 5G networks, considering actual radio environments to mitigate the performance degradation due to interference. Furthermore, to accommodate the dynamic service requirements of private 5G networks, we introduce an automatic dynamic setback technique to adjust the wireless resources in private 5G networks by expanding or contracting the adjustment area in conjunction with the proposed zone-setting method.
