Introduction
The performance specification for 5G is much more demanding than for previous generations of mobile networks, requiring high data rates, (up to 20 Gbps), very low latency, (< 1 mSec), ultra-high reliability, energy efficiency and very high numbers of connected devices. To meet these challenges a completely new air interface has been developed for 5G, 5G New Radio, (5G NR) which must support frequencies from low band all the way up to 100 GHz.
MU-MIMO and beamforming are two core techniques used within 5G networks which lead to multiple signal paths between base station and user equipment, each with different propagation characteristics.
