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 determines that the UE possesses T processing units for calculation of channel state information (CSI) reports. The UE transmits, to a base station, an indication indicating the T processing units. The UE receives, from the base station, a trigger for updating or providing M CSI reports. The UE determines that P processing units of the T processing units are available for calculation of CSI reports. The UE updates or provides N CSI reports. N is an integer smaller than or equal to M and allows processing units assigned for calculation of the N CSI reports to be smaller than or equal to the P processing units.
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 updating or providing M CSI reports;
determining that P processing units of the T processing units are available for calculation of CSI reports; and
updating or providing N CSI reports, wherein N is an integer smaller than or equal to M and allows processing units assigned for calculation of the N CSI reports to be smaller than or equal to the P processing units.
2. The method of claim 1 , wherein each of the N CSI reports occupies a predefined number of processing units for calculation.
3. The method of claim 1 , wherein the N CSI reports are selected based on priority levels of the M CSI reports.
4. The method of claim 3 , wherein each of the N CSI reports has a priority level higher than that of any of the others of the M CSI reports.
5. 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.
6. The method of claim 1 , further comprising:
determining a respective number of processing units allocated for calculation of each of the N CSI reports.
7. 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 updating or providing M CSI reports;
determine that P processing units of the T processing units are available for calculation of CSI reports; and
update or provide N CSI reports, wherein N is an integer smaller than or equal to M and allows processing units assigned for calculation of the N CSI reports to be smaller than or equal to the P processing units.
8. The apparatus of claim 7 , wherein each of the N CSI reports occupies a predefined number of processing units for calculation.
9. The apparatus of claim 7 , wherein the N CSI reports are selected based on priority levels of the M CSI reports.
10. The apparatus of claim 9 , wherein each of the N CSI reports has a priority level higher than that of any of the others of the M CSI reports.
11. The apparatus of claim 7 , 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.
12. The apparatus of claim 7 , 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.
13. 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 updating or providing M CSI reports;
determine that P processing units of the T processing units are available for calculation of CSI reports; and
update or provide N CSI reports, wherein N is an integer smaller than or equal to M and allows processing units assigned for calculation of the N CSI reports to be smaller than or equal to the P processing units.
14. The non-transitory computer-readable medium of claim 13 , wherein each of the N CSI reports occupies a predefined number of processing units for calculation.
15. The non-transitory computer-readable medium of claim 13 , wherein the N CSI reports are selected based on priority levels of the M CSI reports.
16. The non-transitory computer-readable medium of claim 15 , wherein each of the N CSI reports has a priority level higher than that of any of the others of the M CSI reports.
17. The non-transitory computer-readable medium of claim 13 , 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.
18. The non-transitory computer-readable medium of claim 13 , wherein the code is further configured to:
determine a respective number of processing units allocated for calculation of each of the N CSI reports.
