1. A method for wireless communication by a user equipment (UE), the method comprising:
receiving a channel state information (CSI) report configuration, wherein the CSI report configuration is associated with one or more CSI reference signal (CSI-RS) resources, each of the one or more CSI-RS resources comprising a set of ports or port groups, wherein the one or more CSI-RS resources or the set of ports or port groups are indexed;
receiving a list of a plurality of codebooks for the CSI report configuration, wherein each codebook of the plurality of codebooks is associated with a subset of the one or more CSI-RS resources, ports, or port groups of the CSI report configuration, and wherein the list of the plurality of codebooks is an ordered list; and
determining at least one codebook, from the list of the plurality of codebooks, to apply for one or more triggered CSI-RS resources of the one or more CSI-RS resources associated with the CSI report configuration, wherein the determining comprises determining, for each triggered CSI-RS resource of the one or more triggered CSI-RS resources, the codebook, in the list of codebooks, having an order corresponding to an index of the triggered CSI-RS resource.
