Other (than k1) semistatic config for HARQ ACK feedback

Hi Experts.

When UE receives downlink and then send ACK or NACK the UE figures out the PUCCH based on k1 per my understanding.

Is there any other semistatic config for HARQ ACK feedback?

I guess it is always driven by k1.

Even in PDSCH slot aggregation, even for multiple downlink transmission there is single feeback but this also driven by k1 only.


But what about SPS grants that require no DCI.

How are these ACK NACK?

Yes, for SPS, it should be semi static. Need to check the corresponding IE.
