The higher beamforming gain of massive MIMO is expected to improve the link budget shortfall in higher frequency bands. We note that, in multiuser MIMO, the beamforming gain for desired terminal is also effective in overcoming inter-user interference (IUI) caused by channel time variation. Computer simulations show that the SIR performance can be improved over 20 dB by increasing the number of base station antenna elements from 2 to 100.
