Statistical Modelling of Massive MIMO Channel at FR2 Frequency Bands for B5G Networks

Abstract

The rapid growth of extreme data traffic and over occupied networks are the current challenges in the wireless communication networks. However, next generation networks tackle them by utilizing vast frequency bands. These are FR2/FR1 frequency bands that play an important role in next-generation technologies, namely B5G or 6G. mmWave being one of those technologies, also utilize such frequency bands. Nevertheless, massive antennas and propagation characteristics of the channel model describes its behavior and some crucial aspects that need to be considered when operating on FR2 frequency bands for 5G NR networks. This paper analyzes the behavior of a mmWave massive MIMO channel at FR1 and FR2 frequency bands under for specific atmospheric conditions. The channel behavior was simulated using NYUSIM software and the performance metrics include path loss, received power, and path loss exponent of the channel power delay profile.
