Abstract
Apparatuses, methods, and systems are disclosed for preparing CSI. One apparatus includes a processor and a memory with instructions executable by the processor to cause the apparatus to determine a total number of non-zero coefficients associated with a CSI codebook over a set of transmission layers and encode an indication of the total number of non-zero coefficients by selecting a codeword from a plurality of candidate codewords in which the selected codeword identifies the total number of non-zero coefficients. The instructions are executable by the processor to prepare CSI based on the CSI codebook and to transmit the CSI to a base station unit, where the CSI codebook includes a plurality of precoding matrices, and where the CSI includes the selected codeword.
