UE capability for CSI reporting
In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a UE. The UE receives, from a base station, a trigger for reporting M CSI reports, M being an integer greater than 0. The UE determines that P processing units are available for calculation of CSI reports, each of the P processing units indicating a predetermined amount of computing power of the UE. The UE selects N CSI reports from the M CSI reports in accordance with a predetermined rule, N being a maximum integer that allows total processing units assigned for calculation of the N CSI reports to be smaller than or equal to the P processing units. The UE updates the N CSI reports.
1. A method of wireless communication of a user equipment (UE), comprising:
determining that the UE possesses T processing units for calculation of channel state information (CSI) reports;
transmitting, to a base station, an indication indicating the T processing units;
receiving, from the base station, a trigger for reporting M CSI reports, M being an integer greater than 0;
determining that P processing units are available for calculation of CSI reports, each of the P processing units indicating an amount of computing power of the UE;
selecting N CSI reports from the M CSI reports in accordance with a predetermined rule, N being an integer that allows processing units assigned for calculation of the N CSI reports to be smaller than or equal to the P processing units; and
updating the N CSI reports.
2. The method of claim 1 , wherein the predetermined rule defines that the N CSI reports are selected based on priority levels of the M CSI reports.
3. The method of claim 2 , wherein each of the N CSI reports has a priority level higher than that of any of the others of the M CSI reports.
4. The method of claim 1 , further comprising:
determining that L processing units of the T processing units are occupied for calculation of CSI reports, wherein that the P processing units are available is determined based on the T processing units and the L processing units.
5. The method of claim 1 , further comprising:
determining a respective number of processing units allocated for calculation of each of the N CSI reports.
6. 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 that the UE possesses T processing units for calculation of channel state information (CSI) reports;
transmit, to a base station, an indication indicating the T processing units;
receive, from the base station, a trigger for reporting M CSI reports, M being an integer greater than 0;
determine that P processing units are available for calculation of CSI reports, each of the P processing units indicating an amount of computing power of the UE;
select N CSI reports from the M CSI reports in accordance with a predetermined rule, N being an integer that allows processing units assigned for calculation of the N CSI reports to be smaller than or equal to the P processing units; and
update the N CSI reports.
7. The apparatus of claim 6 , wherein the predetermined rule defines that the N CSI reports are selected based on priority levels of the M CSI reports.
8. The apparatus of claim 7 , wherein each of the N CSI reports has a priority level higher than that of any of the others of the M CSI reports.
9. The apparatus of claim 6 , wherein the at least one processor is further configured to:
determine that L processing units of the T processing units are occupied for calculation of CSI reports, wherein that the P processing units are available is determined based on the T processing units and the L processing units.
10. The apparatus of claim 6 , wherein the at least one processor is further configured to:
determine a respective number of processing units allocated for calculation of each of the N CSI reports.
11. A non-transitory computer-readable medium storing computer executable code for wireless communication of a user equipment (UE), comprising code to:
determine that the UE possesses T processing units for calculation of channel state information (CSI) reports;
transmit, to a base station, an indication indicating the T processing units;
receive, from the base station, a trigger for reporting M CSI reports, M being an integer greater than 0;
determine that P processing units are available for calculation of CSI reports, each of the P processing units indicating an amount of computing power of the UE;
select N CSI reports from the M CSI reports in accordance with a predetermined rule, N being an integer that allows processing units assigned for calculation of the N CSI reports to be smaller than or equal to the P processing units; and
update the N CSI reports.
12. The non-transitory computer-readable medium of claim 11 , wherein the predetermined rule defines that the N CSI reports are selected based on priority levels of the M CSI reports.
13. The non-transitory computer-readable medium of claim 12 , wherein each of the N CSI reports has a priority level higher than that of any of the others of the M CSI reports.
14. The non-transitory computer-readable medium of claim 11 , wherein the code is further configured to:
determine that L processing units of the T processing units are occupied for calculation of CSI reports, wherein that the P processing units are available is determined based on the T processing units and the L processing units.
15. The non-transitory computer-readable medium of claim 11 , wherein the code is further configured to:
determine a respective number of processing units allocated for calculation of each of the N CSI reports.
