Definition

The IE CSI-RS-ResourceConfigMobility is used to configure CSI-RS based RRM measurements.

CSI-RS-ResourceConfigMobility ::=   SEQUENCE {
    subcarrierSpacing                   SubcarrierSpacing,
    csi-RS-CellList-Mobility            SEQUENCE (SIZE (1..maxNrofCSI-RS-CellsRRM)) OF CSI-RS-CellMobility,
    ...,
    [[
        refServCellIndex                    ServCellIndex                                                           OPTIONAL    -- Need S

Fields (3)

FieldDescription
subcarrierSpacing
SubcarrierSpacing
Subcarrier spacing of CSI-RS. Only the following values are applicable depending on the used frequency: FR1/FR1-NTN: 15, 30, or 60 kHz FR2-1/FR2-NTN: 60 or 120 kHz FR2-2: 120, 480, or 960 kHz
csi-RS-CellList-Mobility
SEQUENCE (SIZE (1..maxNrofCSI-RS-CellsRRM)) OF CSI-RS-CellMobility
List of cells for CSI-RS based RRM measurements.
refServCellIndex
ServCellIndex · OPTIONAL Need S
since v15.8.0
Indicates the serving cell providing the timing reference for CSI-RS resources without associatedSSB . The field may be present only if there is at least one CSI-RS resource configured without associatedSSB . If this field is absent, the UE shall use the timing of the PCell for measurements on the CSI-RS resources without associatedSSB . The CSI-RS resources and the serving cell indicated by refServCellIndex for timing reference should be located in the same band.
