16.14.3.2.1 Handover

The same principle as described in 9.2.3.2 applies unless hereunder specified:

During mobility between NTN and TN, a UE is not required to connect to both NTN and TN at the same time.

NOTE: NTN TN handover refers to mobility in both directions, i.e. from NTN to TN (hand-in) and from TN to NTN (hand-out).

DAPS handover is not supported for NTN in this release of the specification.

UE may support mobility between gNBs operating with NTN payloads, transparent and/or regenerative, in different orbits (e.g., GSO, NGSO at different altitudes).

RACH-less handover as specified in 9.2.3.6, in TS 38.321 [6] and in TS 38.331 [12] is supported in NTNs.
