1. A method for communication by a user equipment (UE), comprising:
receiving, from a network entity, a channel state information (CSI) report configuration configuring the UE for reporting at least a plurality of frequency domain (FD) bases information for each of a plurality of layers associated with a common FD basis per layer;
identifying, from a set of candidate FD bases, one or more FD bases for each layer, wherein the identified one or more FD bases for each layer comprises the common FD basis; and
providing a report indicating remaining identified FD bases other than the common FD basis for each layer according to the CSI report configuration, wherein:
the common FD basis corresponds to a strongest FD basis,
the remaining identified FD bases are selected from an intermediate set of FD bases that comprises a subset of the set of candidate FD bases, and
the strongest FD basis is located within the intermediate set.
