One of the technologies aimed to provide large increase in data rate, enhanced spectral efficiency, transmit power efficiency, high sum rates, and increase link reliability for the fifth generation network (5G) is the massive multiple input multiple output (MIMO) antenna system. The projected benefits of massive MIMO depend on the propagation environment. However, due to the non wide-sense stationarity properties of massive MIMO, small scale characterization (SSC) is not enough for modeling its propagation channel as the spatial domain is also required. Giving consideration to the dynamic adaptation of the elevation angles which is not captured in 2D channel models will open up new possibilities for 3D beamforming which will introduce considerable performance gains for 5G network capacity enhancement. In this paper therefore, we review the various non wide-sense stationary channel parameters for characterizing massive MIMO channel particularly in the 3D plane and their methods of measurement, All through the discussion, we identified outstanding research challenges in these areas and their future directions.
