1. A method for wireless communications by a user equipment (UE), comprising:
processing channel state information (CSI) reference signal (CSI-RS) measurements to generate a plurality of coefficients based on a codebook, the codebook comprising a plurality of sparsity pattern candidates;
determining a sparsity pattern based on the plurality of coefficients generated when processing the CSI-RS measurements;
computing one or more quantized coefficients based on the sparsity pattern and the plurality of coefficients; and
transmitting the one or more quantized coefficients to a network entity.
