...We then demonstrate the way to quantify the SE and finally present recent results on the fundamental SE limits of Massive MIMO, which are not determined by pilot contamination (as is the case for spatially uncorrelated channels [7], [12]) but the ability to acquire accurate channel statistics....

...With MR and uncorrelated Rayleigh fading, the following result was proved in [7] and follows directly from Corollary 1....
[...]
...The above lower bound has dominated since the early articles on Massive MIMO [7], [22], [50] and is achieved when the UE treats the mean of its precoded channel as the true one....

...Another, seemingly simpler, but also less explored option is the use of very large antennas arrays at the base stations (BSs) [5]....
[...]
...The use of massively many antennas was advocated for the first time in [5] and has since then received growing research interest [9], [10], [11]....
