Abstract: Certain aspects of the present disclosure provide techniques for channel state information (CSI) reporting with frequency domain (FD) compression. A method that can be performed by a user equipment (UE) includes determining the size of the intermediate set based on one or more parameters included in the CSI report configuration, determining one or more FD bases for each layer based on the intermediate set, wherein the one or more FD bases are characterized by an M value indicative of a number of the one or more FD bases and based on the CSI report configuration, and reporting the one or more FD bases for each layer based on the size of the intermediate set.
