Is HO possible between NR SA and ENDC NR cell and vice versa?

Hi Experts,
Is HO possible between NR SA and ENDC NR cell and vice versa?
Is it by RRC release or by measurement?

Effectively its an inter RAT handover so can be both.
But generally inter RAT handover are non-measurement based.

Ok is it by A3/A5 event.
Why it’s inter RAT we are doing HO between NR cells only?

Primary cell will change from 5G to 4G.
So in my view it will be inter RAT to 4G and then 5G will be added again via RRC Reconfig
B1/B2 based.

For NR SA to ENDC NR cell I mean i.e. NR SA cell to ENDC Pscell. No LTE in between.

EN-DC in this case the LTE is the signaling leg, therefore, IRAT.

Correct!
