Fields (11)

FieldDescription
carrierFreq
ARFCN-ValueEUTRA
Identifies E-UTRA carrier frequency for which this configuration is valid. Network does not configure more than one MeasObjectEUTRA for the same physical frequency, regardless of the E-ARFCN used to indicate this.
allowedMeasBandwidth
EUTRA-AllowedMeasBandwidth
The maximum allowed measurement bandwidth on a carrier frequency as defined by the parameter Transmission Bandwidth Configuration "N RB " TS 36.104 [33].
cellsToRemoveListEUTRAN
EUTRA-CellIndexList · OPTIONAL Need N
List of cells to remove from the cell list.
cellsToAddModListEUTRAN
SEQUENCE (SIZE (1..maxCellMeasEUTRA)) OF EUTRA-Cell · OPTIONAL Need N
List of cells to add/ modify in the cell list.
excludedCellsToRemoveListEUTRAN
EUTRA-CellIndexList · OPTIONAL Need N
since v17.0.0
List of cells to remove from the exclude-list of cells.
excludedCellsToAddModListEUTRAN
SEQUENCE (SIZE (1..maxCellMeasEUTRA)) OF EUTRA-ExcludedCell · OPTIONAL Need N
since v17.0.0
List of cells to add/ modify in the exclude-list of cells.
eutra-PresenceAntennaPort1
EUTRA-PresenceAntennaPort1
When set to true , the UE may assume that at least two cell-specific antenna ports are used in all neighbouring cells.
eutra-Q-OffsetRange
EUTRA-Q-OffsetRange · OPTIONAL Need R
Used to indicate a cell, or frequency specific offset to be applied when evaluating triggering conditions for measurement reporting. The value is in dB. Value dB-24 corresponds to -24 dB, value dB-22 corresponds to -22 dB and so on.
widebandRSRQ-Meas
BOOLEAN
If set to true , the UE shall, when performing RSRQ measurements, use a wider bandwidth in accordance with TS 36.133 [40]. The network may set the field to true if the measurement bandwidth indicated by allowedMeasBandwidth is 50 resource blocks or larger; otherwise the network sets this field to false .
associatedMeasGap-r17
MeasGapId-r17 · OPTIONAL Need R
since v17.0.0
Indicates the associated measurement gap for measuring this EUTRA frequency. If this field is absent, the associated meaurment gap is the gap configured via gapFR1 or gapUE .
measSequence-r18
MeasSequence-r18 · OPTIONAL Need R
since v18.0.0
Indicates the recommended sequence for intra/inter-RAT intra/inter-frequency measurement. Value 1 means the corresponding frequency is measured firstly. Value 2 means the corresponding frequency is measured secondly and so on. If more than one frequency is configured with the same value, it means no recommended sequence among these frequencies. If not configured, it means there is no recommended sequence for the corresponding frequency. This field is only configured for NR standalone or if the measObject is associated to the MCG.
