ENUMERATED {true} · OPTIONAL Cond SpCellOnly
If the field is present and UE supports measurementEnhancement-r16 , the UE shall apply the enhanced intra-NR and inter-RAT EUTRAN RRM requirements to support high speed up to 500 km/h as specified in TS 38.133 [14]. If the field is present and UE supports intraNR-MeasurementEnhancement-r16 , the UE shall apply enhanced intra-NR RRM requirement to support high speed up to 500 km/h as specified in TS 38.133 [14]. If the field is present and UE supports interRAT-MeasurementEnhancement-r16 , the UE shall apply enhanced inter-RAT EUTRAN RRM requirement to support high speed up to 500 km/h as specified in TS 38.133 [14]. This parameter only applies to the serving frequency of SpCell.
highSpeedDemodFlag-r16
ENUMERATED {true} · OPTIONAL Need R
If the field is present and UE supports demodulationEnhancement-r16 , the UE shall apply the enhanced demodulation processing for HST-SFN joint transmission scheme with velocity up to 500km/h as specified in TS 38.101-4 [59]. This parameter only applies to SpCell.
