HO from 5G to 4G

During EPS fallback, gNB finally sends a HO command to UE or RRC release with redirection message to UE
Please clarify

it is upto NW to decide whether want to use RRC_IDLE or RRC_CONNECTED during EPS Fallback.
RRC_IDLE use by 5G RAN : RRCRelease with EUTRAN Freq
RRC_CONNECTED : Handovercommand wirth Target cell as EUTRA
