1. A method for wireless communication at a user equipment (UE), comprising:
receiving a channel state information report configuration that includes a set of channel state information resources and a plurality of codebooks for a plurality of sets of antenna ports associated with the set of channel state information resources, wherein the plurality of codebooks include at least a first codebook for a first set of antenna ports and a second codebook for a second set of antenna ports that is different than the first set of antenna ports;
identifying a first set of channel state information parameters associated with the first codebook;
identifying a second set of channel state information parameters associated with the second codebook; and
transmitting a channel state information report that includes the first set of channel state information parameters and a third set of differential channel state information parameters, wherein the third set of differential channel state information parameters indicate a difference between corresponding channel state information parameters of the second set of channel state information parameters and the first set of channel state information parameters.
