1. A user equipment (UE) comprising:
a processor; and
a memory storing instructions that, when executed by the processor, configure the UE to:
decode a channel state information (CSI) reporting configuration associated with a first transmission and reception point (TRP) and a second TRP, the CSI reporting configuration including at least one codebook configuration, the at least one codebook including at least one of a rank restriction configuration or a codebook subset restriction (CBSR) configuration, the at least one of the rank restriction configuration or the CBSR configuration corresponding to at least one of a particular type of TRP measurement, a particular TRP of the first TRP or the second TRP, or channel measurement resources (CMRs) associated with at least one of the first TRP or the second TRP;
wherein a first set of CMRs are configured for single-TRP measurements associated with the first TRP, a second set of CMRs are configured for single-TRP measurements associated with the second TRP, and a third set of CMRs are configured for multi-TRP measurements associated with both the first TRP and the second TRP; and
perform one or more CSI measurements based on the CSI reporting configuration.
