Adaptive training‐feedback scheme for FDD in massive MIMO systems

Abstract Accurate acquisition of channel state information (CSI) is crucial but difficult in frequency division duplex (FDD) massive multiple‐input multiple‐output (MIMO) systems. To improve the estimation accuracy and to minimize the training consumption, an adaptive training‐feedback scheme based...
