1. A method of wireless communication performed by a user equipment (UE), comprising:
receiving multiple channel state information (CSI) report configurations that include at least a first CSI report configuration and a second CSI report configuration that are associated with one or more CSI reference resources,
wherein the second CSI report configuration includes an indication that the first CSI report configuration is a reference CSI report configuration for the second CSI report configuration;
determining a dependency between the first CSI report configuration and the second CSI report configuration;
calculating at least one of a first CSI for the first CSI report configuration or a second CSI for the second CSI report configuration based at least in part on an assumption of a joint transmission using the one or more CSI reference resources, wherein the assumption is based at least in part on the determination of the dependency; and
reporting at least one of the first CSI in a first CSI report or the second CSI in a second CSI report.
