To support gains in frequency division duplex multi-user multiple-input multiple-output scenarios, Channel State Information (CSI) is required at the Base Stations (BSs). For this purpose, Mobile Stations (MSs) report quantized CSI based on Grassmannian codebooks, that are common to MSs and BSs. Dep...
