Hey experts

I have one question regarding Connected mode DRX.

For periodic CSI and periodic SRS transmission, the UE MUST be in ACTIVE DRX state.

First of all, is my understanding correct?

Secondly, why is so?

Why cant UE be in INACTIVE state and then shift to ACTIVE state when it is about to receive the data in the PDSCH?

To receive the PDSCH data, first UE need to decode DCI, and UE is unware about DCI scheduling, so UE look out for the DCI scheduling in every TTI.

Your understanding is correct.
