Csi type ii codebook

WebMultiple Input Multiple Output (MIMO) improvements include enhancements to the CSI Type II codebook for MU-MIMO, Multiple Transmission and Reception (multi-TRP/panel transmissions), multi-beam operations in Frequency Range 2 (FR2) for millimeter wave, and low Peak-to-Average Power Ratio (PAPR) reference signals. ... 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
