An Improved Measurement Method for Radio Frequency Exposure From 5G NR Base Stations

In this publication, an improved measurement method is proposed for the quantification of the radio frequency exposure from 5G NR base stations in sub-6 GHz frequency range. The method is based on the code selective measurements of all resource elements in the resource grid and enables an estimation of the exposure at maximum data transmission. In particular, it allows the quantification of the ratio between traffic resource elements and synchronization resource elements. The use of this method is presented in this publication and some preliminary results of the laboratory measurements are demonstrated, which were performed using a code selective measuring receiver implementing the proposed method for analyzing the full 5G resource grid.
