Abstract

A method for processing channel state information (CSI) for a non-serving cell is disclosed. The method includes receiving downlink control information (DCI) for triggering an aperiodic CSI report; determining whether the aperiodic CSI report is an aperiodic CSI report for the non-serving cell; and determining that a CSI computation delay requirement for the aperiodic CSI report corresponds to a predefined first CSI computation delay requirement, based on a determination that the aperiodic CSI report belongs to the aperiodic CSI report for the non-serving cell, where the first CSI computation delay requirement is greater than or equal to a second CSI computation delay requirement corresponding to a serving cell.

First claim

What is claimed is:

1. A method for processing channel state information (CSI) for a non-serving cell, applied to a user equipment and comprising:
receiving downlink control information (DCI) for triggering an aperiodic CSI report;
determining whether the aperiodic CSI report is an aperiodic CSI report for the non-serving cell; and
determining that a CSI computation delay requirement for the aperiodic CSI report corresponds to a predefined first CSI computation delay requirement, based on a determination that the aperiodic CSI report is the aperiodic CSI report for the non-serving cell, the first CSI computation delay requirement being greater than or equal to a second CSI computation delay requirement corresponding to a serving cell;
wherein determining whether the aperiodic CSI report is the aperiodic CSI report for the non-serving cell comprises:
obtaining, from a network configuration, a measurement signal associated with the aperiodic CSI report;
determining whether a physical cell identifier (PCI) of the measurement signal corresponds to the non-serving cell; and
determining that the aperiodic CSI report is the aperiodic CSI report for the non-serving cell based on a determination that the PCI of the measurement signal corresponds to the non-serving cell.

2. The method of claim 1 , further comprising:
obtaining measurement resource configuration information associated with the aperiodic CSI report;
determining whether the measurement resource configuration information satisfies a preset condition; and
determining that the CSI computation delay requirement for the aperiodic CSI report corresponds to the predefined first CSI computation delay requirement, based on a determination that the measurement resource configuration information satisfies the preset condition.

3. The method of claim 2 , wherein the preset condition comprises at least one of:
the measurement resource configuration information including measurement gap configuration information,
the measurement resource configuration information including frequency point configuration information different from frequency point configuration information for the serving cell, or
the measurement resource configuration information including sub-carrier-space configuration information different from sub-carrier-space configuration information for the serving cell.

4. The method of claim 2 , further comprising:
determining that the CSI computation delay requirement for the aperiodic CSI report corresponds to the second CSI computation delay requirement, based on a determination that the measurement resource configuration information does not satisfy the preset condition.

5. The method of claim 1 , wherein the measurement signal is information from the measurement resource configuration information.

6. The method of claim 1 , wherein the measurement signal is a non-zero power CSI reference signal (NZP CSI-RS), a synchronization signal and PBCH block (SSB), or a CSI-inference measurement (CSI-IM) used for measurement.

7. An electronic device, comprising:
a processor; and
a memory storing a computer program executable on the processor to cause the processor to:
receive downlink control information (DCI) for triggering an aperiodic CSI report;
determine whether the aperiodic CSI report is an aperiodic CSI report for the non-serving cell; and
determine that a CSI computation delay requirement for the aperiodic CSI report corresponds to a predefined first CSI computation delay requirement, based on a determination that the aperiodic CSI report is the aperiodic CSI report for the non-serving cell, the first CSI computation delay requirement being greater than or equal to a second CSI computation delay requirement corresponding to a serving cell;

wherein the processor configured to determine whether the aperiodic CSI report is the aperiodic CSI report for the non-serving cell is configured to:
obtain, from a network configuration, a measurement signal associated with the aperiodic CSI report;
determine whether a physical cell identifier (PCI) of the measurement signal corresponds to the non-serving cell; and
determine that the aperiodic CSI report is the aperiodic CSI report for the non-serving cell based on a determination that the PCI of the measurement signal corresponds to the non-serving cell.

8. The electronic device of claim 7 , wherein the computer program is executable on the processor to further cause the processor to:
obtain measurement resource configuration information associated with the aperiodic CSI report;
determine whether the measurement resource configuration information satisfies a preset condition; and
determine that the CSI computation delay requirement for the aperiodic CSI report corresponds to the predefined first CSI computation delay requirement, based on a determination that the measurement resource configuration information satisfies the preset condition.

9. The electronic device of claim 8 , wherein the preset condition comprises at least one of:
the measurement resource configuration information including measurement gap configuration information,
the measurement resource configuration information including frequency point configuration information different from frequency point configuration information for the serving cell, or
the measurement resource configuration information including sub-carrier-space configuration information different from sub-carrier-space configuration information for the serving cell.

10. The electronic device of claim 8 , wherein the computer program is executable on the processor to further cause the processor to:
determine that the CSI computation delay requirement for the aperiodic CSI report corresponds to the second CSI computation delay requirement, based on a determination that the measurement resource configuration information does not satisfy the preset condition.

11. The electronic device of claim 7 , wherein the measurement signal is information from measurement resource configuration information.

12. The electronic device of claim 7 , wherein the measurement signal is a non-zero power CSI reference signal (NZP CSI-RS), a synchronization signal and PBCH block (SSB), or a CSI-inference measurement (CSI-IM) used for measurement.

13. A non-transitory computer-readable storage medium storing a computer program, the computer program being executable on a processor to cause the processor to:
receive downlink control information (DCI) for triggering an aperiodic CSI report;
determine whether the aperiodic CSI report is an aperiodic CSI report for the non-serving cell; and
determine that a CSI computation delay requirement for the aperiodic CSI report corresponds to a predefined first CSI computation delay requirement, based on a determination that the aperiodic CSI report is the aperiodic CSI report for the non-serving cell, the first CSI computation delay requirement being greater than or equal to a second CSI computation delay requirement corresponding to a serving cell;
wherein the processor configured to determine whether the aperiodic CSI report is the aperiodic CSI report for the non-serving cell is configured to:
obtain, from a network configuration, a measurement signal associated with the aperiodic CSI report;
determine whether a physical cell identifier (PCI) of the measurement signal corresponds to the non-serving cell; and
determine that the aperiodic CSI report is the aperiodic CSI report for the non-serving cell based on a determination that the PCI of the measurement signal corresponds to the non-serving cell.
