I. Introduction
Due to the rapid development of mobile networks, particular focus is attributed to the expansion of 5G NR in the sub-6 GHz band (FR1). In the further roll-out of 5G NR in the band around 3.6 GHz, massive MIMO base stations are used. These allow for advanced features including beam steering and, thus, provide high capacity and throughput as well as short latency times. Due to significant differences in broadcast and traffic antenna patterns, it is not possible to extrapolate to maximal possible exposure as in established mobile radio systems by evaluating the control or synchronisation signal and applying the spectral ratio between the control signal and the entire bandwidth resp. duty cycle.
