The performance of a multicell large scale antenna system (LSAS) is conveniently characterized by capacity lower-bounds that explicitly account for channel-estimation error, the type of linear spatial multiplexing/de-multiplexing (conjugate beamforming or zero-forcing on the forward link and matched-filtering or zero-forcing on the reverse link), power-control, non-coherent inter-cell interference, and coherent inter-cell interference due to pilot-contamination.
