This study addresses the pilot scheduling problem in multiuser multi-cell massive multiple-input–multipleoutput (MIMO) systems, aiming at mitigating the inter-cell interference (pilot contamination), which constitutes a bottleneck of the system performance. First, the authors investigate the pilot reuse and scheduling problem in cellular systems with unlimited number of base station antennas, only considering the large fading coefficients. Three lowcomplexity pilot scheduling schemes are then… CONTINUE READING
