1. A user equipment (“UE”) for wireless communication comprising:
at least one memory; and
at least one processor coupled with the at least one memory and configured to cause the UE to:
determine a total number of non-zero coefficients associated with a Channel State Information (“CSI”) codebook over a set of transmission layers, wherein the CSI codebook comprises a plurality of precoding matrices;
encode an indication of the total number of non-zero coefficients based on a codeword, wherein the codeword identifies the total number of non-zero coefficients;
prepare CSI based on the CSI codebook, wherein the CSI comprises the codeword; and
transmit, to a base station, the CSI.
