Packets from UE transmitting towards gNB getting lost

Hi All.

Im facing issue in NR:
Scenario - Testing
UE transmitting something towards gNB
If any packet loss then its going with RV0, RV2, RV3, RV1
Packet is getting loss completely.
Is not getting passes in any RV.

What to check and how to resolve it?
Any suggestions will be helpful.

Is this happening for all 16 harq processes?

Yes.

But we have 4 harq process as of now in lab scenario.

Change chase combining into something else.

Or troubleshoot chase combining with R&D.

Or better said: change incremental redundancy into chase combining.
