Hi Experts.

What is the 5G latency for pattern DDDSUUDDDD for real UE?

2

For pattern DDDSUUDDDD, is it allowed to send the HARQ for DL slot2 at distance 11 where next S slot comes?

Will that be ideal case?
Does it add delay?

Assume UL slots isn’t used for uci HARQ and only S slot is used for uci harq.

Is it ideal case to send harq of DL slot2 to be on distance 11 slots after?

Distance 11 from slot 2 is next S slot.

4

Yes, but then I see Throughput goes down.

Sometimes down (lower than expected) and sometimes Ok.

5

May be depends how many UCIs bits can be reported in that slot based on PUCCH format, size etc.

Do you see DL BLER ?

6

I see high CRC bad. DTX on PUCCH CSI.

Not that much BLER.

7

CRC bad is different problem and all reported UCIs will be nacked.

DTX looks PDCCH not properly decoded by UE or not received.

But why if I don’t configure harq feedback for slot2 to be send on distance 11 then no issue?

If I do that then I see DL slot2 isn’t getting scheduled because on UL slot no uci harq mutiplexed with pusch.

And sometimes it works fine and sometimes not.

When not then I see DL throughput is fluctuating.

Do you see pucch in S slot with k1 11? May be k1 selection is Dynamic in other cases ?
