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 … WebCertain aspects of the present disclosure provide techniques for channel state information (CSI) processing occupation determination that can be used even in multiple transmission
WebIn 3GPP new radio system, two types of codebook, namely Type-l and Type-2 codebook, have been standardized for the channel state information (CSI) feedback in the support of advanced MIMO operation. Both types of codebook are constructed from 2-D DFT based grid of beams, and enable the CSI feedback of beam selection as well as PSK based co … WebIn addition, for Type I codebooks, NR also supports CSI feedback for multipanel antenna arrays. The Type I codebook in NR is designed for SU- or MU-MIMO operation having moderate CSI feedback overhead and relatively low UE complexity to decide the preferred precoder. Both 1D and 2D antenna port layouts are supported with 2, 4, 8, 12, 16, 24 ...
