Hi Experts.

Does RRC pre configures CSI resources for Aperiodic reporting?

If yes, which IE contains the CSI resources for Aperiodic CSI reporting?

You can configure periodic or aperiodic CQI in RRC connection reconfiguration.

There is cqireportconfigr10.

Yes, that is an option.

But do both Periodic and Aperiodic use same CSI resources for measurement?

Reporting mode is different like rm 2-0 ,rm 2-1 for aperiodic.

Periodic having periodicity defined.

Which measurements you mean here?

Aperiodic CSI reports gets delivered on PUSCH resources.

UE gets these resources from UL DCI.

Could you please tell me about CSI resources for Aperiodic CQI measurement?

How that is configured, which resources are used?

Do we use same CSI resources for periodic and Aperiodic reporting?
