Downlink Interference Measurement in 4G/5G Systems with Dynamic Spectrum Sharing

Abstract

Dynamic spectrum sharing is a new technology that enables LTE and 5G to be used in parallel in the same frequency band. In other words, it is an activation mechanism that allows 5G NR and 4G LTE to coexist while sharing the same frequency spectrum. In the long run, DSS allows mobile network operators to re-use their frequency bands in order to provide increased 5G coverage. In this paper we measure the effect of interference for a DL 5G system using two different mobile terminals. The main purpose of this study is to compare the DL interference of an adaptive system model for 5G mobile communications applications.
