1. A method of wireless communication performed by a user equipment (UE), comprising:
identifying a plurality of channel state information (CSI) reference signal (RS) resource groups, wherein each CSI RS resource group, of the plurality of CSI RS resource groups, includes one or more CSI RS resources;
identifying, based at least in part on the plurality of CSI RS resource groups, a plurality of hypotheses;
identifying, based at least in part on the plurality of CSI RS resource groups and the plurality of hypotheses, a plurality of hypothesis groups, wherein each hypothesis group, of the plurality of hypothesis groups, includes one or more hypotheses from the plurality of hypotheses;
identifying an active subset of hypothesis groups of the plurality of hypothesis groups and an inactive subset of hypothesis groups of the plurality of hypothesis groups;
reporting, to one or more transmit receive points (TRPs) in a multi-TRP deployment and for the plurality of hypothesis groups, a corresponding plurality of CSIs, wherein each CSI, of the corresponding plurality of CSIs, corresponds to at least one hypothesis of a respective hypothesis group of the plurality of hypothesis groups; and
forgoing reporting of one or more CSIs for the inactive subset of hypothesis groups.
