Question: In a Non-Geostationary Satellite Orbit (NGSO) scenario, what determines if UL and DL HARQ process enhancements are applicable for a UE that supports both GSO and NGSO scenarios?
Option 1: Presence of the `ntn-HarqEnhNGSO-Support-r18` field in the UE's capabilities.
Option 2: Absence of any `ntn-RRC-HarqDisable*` fields in the UE's capabilities.
Option 3: The UE's support for at least one `ntn-UplinkHarq-ModeB-r18` feature.
Option 4: The network's configuration for NGSO scenarios, regardless of UE capabilities.
Explanation: According to the specifications, if the `ntn-HarqEnhNGSO-Support-r18` field is included in the UE's capabilities, it indicates that the UL and DL HARQ process enhancements are applicable in NGSO scenarios for a UE that supports both GSO and NGSO scenarios. Without this field, these enhancements are not applicable in NGSO scenarios.
