| Abstract(in English) | Two years after the first regulation of Local 5G was institutionalized, new spectrums are added to Local 5G and some of the bands are allowed to be used in outdoor. Release of 5G SA(Standalone) gNBs can also encourage the deployment of Local 5G. As Local 5G becomes more widespread, it may occur that multiple Local 5G gNBs can be installed in the same building by different operators. In this paper, we estimate the interference between Local 5G gNBs of multiple operators for spectrum sharing in a building, and discuss the operation of proximity Local 5G gNBs. |
