1. A method for wireless communications by a user equipment (UE), comprising:
receiving a channel state information (CSI) reporting configuration, the CSI reporting configuration including a number of frequency domain (FD) units and a FD unit size for CSI reporting;
determining a number of CSI processing units at the UE, at least one CSI time threshold, or both based on the number of FD units, the FD unit size, or both, wherein the number of CSI processing units at the UE corresponds to a number of concurrent CSI calculations at the UE, wherein determining the number of CSI processing units comprises:
determining a first number of CSI processing units when the number of FD units for CSI reporting is equal to or below a first threshold or when the FD unit size for CSI reporting is equal to or larger than a second threshold; and
determining a second number of CSI processing units when the number of FD units for CSI reporting is above the first threshold or when the FD unit size for CSI reporting is below the second threshold; and
processing the CSI report based on the number of CSI processing units at the UE, the at least one CSI time threshold, or both.
