receiving a first trigger for reporting the first CSI report;

receiving a second trigger for reporting the second CSI report;

determining that E processing units are remaining available prior to updating the first CSI report and the second CSI report, E being an integer;

determining that X processing units are required to update each of the first CSI report and the second CSI report individually, X being an integer;

determining that R processing units are available after committing to update the first CSI report and the second CSI report, R being equal to E minus X; and

updating the first CSI report and the second CSI report based on a same CSI calculation.

2. The method of claim 1 , further comprising:

receiving a first CSI report configuration defining reporting of the first CSI report and a second CSI report configuration defining reporting of the second CSI report, wherein the determination that the first CSI report and the second CSI report contain the same CSI information is made based on the first CSI report configuration and the second CSI report configuration.

3. The method of claim 2 , wherein the first CSI report configuration and the second CSI report configuration are associated with a same reference signal for CSI measurement and a same report quantity.

5. The method of claim 2 , wherein the first CSI report configuration specifies that the first CSI report is to be transmitted on a first uplink channel, wherein the second CSI report configuration specifies that the second CSI report is to be transmitted on a second uplink channel.

6. The method of claim 5 , wherein the uplink channel is a physical uplink control channel (PUCCH) or a physical uplink share channel (PUSCH).

7. The method of claim 5 , further comprising:

transmitting the first CSI report on the first uplink channel; and

transmitting the second CSI report on the second uplink channel.

8. An apparatus for wireless communication, the apparatus being a user equipment (UE), comprising:

a memory; and

at least one processor coupled to the memory and configured to:

determine to report channel state information (CSI) reports;

determine that a first CSI report and a second CSI report to be reported contain same CSI information;

determine that total processing units required for updating the first CSI report and the second CSI report are processing units required for updating one of the first CSI report and the second CSI report;

receive a first trigger for reporting the first CSI report;

receive a second trigger for reporting the second CSI report;

determine that E processing units are remaining available prior to updating the first CSI report and the second CSI report, E being an integer;

determine that X processing units are required to update each of the first CSI report and the second CSI report individually, X being an integer;

determine that R processing units are available after committing to update the first CSI report and the second CSI report, R being equal to E minus X; and

update the first CSI report and the second CSI report based on a same CSI calculation.

9. The apparatus of claim 8 , wherein the at least one processor is further configured to:

receive a first CSI report configuration defining reporting of the first CSI report and a second CSI report configuration defining reporting of the second CSI report, wherein the determination that the first CSI report and the second CSI report contain the same CSI information is made based on the first CSI report configuration and the second CSI report configuration.

10. The apparatus of claim 9 , wherein the first CSI report configuration and the second CSI report configuration are associated with a same reference signal for CSI measurement and a same report quantity.

11. The apparatus of claim 9 , wherein the first CSI report configuration specifies that the first CSI report is to be transmitted to a first TRP, wherein the second CSI report configuration specifies that the second CSI report is to be transmitted to a second TRP.

12. The apparatus of claim 9 , wherein the first CSI report configuration specifies that the first CSI report is to be transmitted on a first uplink channel, wherein the second CSI report configuration specifies that the second CSI report is to be transmitted on a second uplink channel.

13. The apparatus of claim 12 , wherein the uplink channel is a physical uplink control channel (PUCCH) or a physical uplink share channel (PUSCH).

14. The apparatus of claim 12 , wherein the at least one processor is further configured to:

transmit the first CSI report on the first uplink channel; and

transmit the second CSI report on the second uplink channel.

15. A non-transitory computer-readable medium storing computer executable code for wireless communication of a user equipment (UE), comprising code to:

determine to report channel state information (CSI) reports;

determine that a first CSI report and a second CSI report to be reported contain same CSI information;

determine that total processing units required for updating the first CSI report and the second CSI report are processing units required for updating one of the first CSI report and the second CSI report;

receive a first trigger for reporting the first CSI report;

receive a second trigger for reporting the second CSI report;

determine that E processing units are remaining available prior to updating the first CSI report and the second CSI report, E being an integer;

determine that X processing units are required to update each of the first CSI report and the second CSI report individually, X being an integer;

determine that R processing units are available after committing to update the first CSI report and the second CSI report, R being equal to E minus X; and

update the first CSI report and the second CSI report based on a same CSI calculation.

16. The non-transitory computer-readable medium of claim 15 , wherein the code is further configured to:

receive a first CSI report configuration defining reporting of the first CSI report and a second CSI report configuration defining reporting of the second CSI report, wherein the determination that the first CSI report and the second CSI report contain the same CSI information is made based on the first CSI report configuration and the second CSI report configuration.

17. The non-transitory computer-readable medium of claim 16 , wherein the first CSI report configuration and the second CSI report configuration are associated with a same reference signal for CSI measurement and a same report quantity.
