WebIn particular, two types of codebooks (namely Type I and Type II codebooks) are introduced with different resolution and overhead. Although the Type I codebook based scheme requires lower feedback overhead, its channel state information (CSI) reconstruction and beamforming performance are not as good as those from the Type II codebook based … WebA. CSI Feedback with Type-2 Codebook According to [2] [3], Type-2 codebook based CSI feedback enables more explicit channel feedback than Type-1 based CSI feedback in the sense that both beam direction and amplitude are reported by the UE in the CSI feedback. As a result, channel can be characterized with more accurate spatial and amplitude

WebThe type II codebook based CSI feedback also reports wideband and subband polarization information for the selected beams, thereby enabling more accurate CSI to be obtained. This in turn provides improved precoded MIMO transmission through the network. Webtion (CSI) reconstruction and beamforming performance are not as good as those from the Type II codebook based scheme. However, since the Type I codebook based scheme has been widely used in 4G systems for many years, replacing it by the Type II codebook based scheme overnight is too costly to be an option.
