description Certain aspects of the present disclosure provide techniques for channel state information (CSI) reporting with frequency compression. A method that can be performed by a user equipment (UE) includes receiving a CSI report configuration. The CSI report configuration configures the UE for reporting precoding matrix information including, for each layer, a plurality of selected beams L, a plurality of frequency domain compression bases F for the L beams, and a subset of linear combination coefficients associated with the frequency domain compression bases and beams. The UE can determine a number of coefficients to report for a higher rank based on a configured maximum number of coefficients to report for a lower rank.
