Fields (23)

Field	Description
measId MeasId	Identifies the measurement identity for which the reporting is being performed.
measResultServingMOList MeasResultServMOList since v15.2.0	Measured results of measured cells with reference signals indicated in the serving cell measurement objects including measurement results of SpCell, configured SCell(s) and best neighbouring cell within measured cells with reference signals indicated in on each serving cell measurement object. If the sending of the MeasurementReport message is triggered by a measurement configured by the field sl-ConfigDedicatedForNR received within an E-UTRA RRCConnectionReconfiguration message (i.e. CBR measurements), this field is not applicable and its contents is ignored by the network.
measResultNeighCells CHOICE { · OPTIONAL
measResultListNR MeasResultListNR	List of measured results for the maximum number of reported best cells for an NR measurement identity.
measResultListEUTRA MeasResultListEUTRA	List of measured results for the maximum number of reported best cells for an E-UTRA measurement identity.
measResultListUTRA-FDD-r16 MeasResultListUTRA-FDD-r16 since v16.0.0	List of measured results for the maximum number of reported best cells for a UTRA-FDD measurement identity.
sl-MeasResultsCandRelay-r17 OCTET STRING since v17.0.0	Measurement result(s) of candiate L2 U2N relay UE(s).
measResultServFreqListEUTRA-SCG MeasResultServFreqListEUTRA-SCG · OPTIONAL since v15.6.0	Measured results of the E-UTRA SCG serving frequencies: the measurement result of PSCell and each SCell, if any, and of the best neighbouring cell on each E-UTRA SCG serving frequency.
measResultServFreqListNR-SCG MeasResultServFreqListNR-SCG · OPTIONAL since v15.6.0	Measured results of the NR SCG serving frequencies: the measurement result of PSCell and each SCell, if any, and of the best neighbouring cell on each NR SCG serving frequency.

measResultSFTD-NR MeasResultCellSFTD-NR · OPTIONAL since v15.6.0	SFTD measurement results between the PCell and the NR PScell in NR-DC.
measResultCellListSFTD-NR MeasResultCellListSFTD-NR · OPTIONAL since v15.7.0	SFTD measurement results between the PCell and the NR neighbour cell(s) in NR standalone.
measResultForRSSI-r16 MeasResultForRSSI-r16 · OPTIONAL since v16.0.0	Includes measured RSSI result in dBm (see TS 38.215 [9]) and channelOccupancy which is the percentage of samples when the RSSI was above the configured channelOccupancyThreshold for the associated reportConfig .

measResultRxTxTimeDiff-r17 MeasResultRxTxTimeDiff-r17 · OPTIONAL since v17.0.0
sl-MeasResultServingRelay-r17 OCTET STRING · OPTIONAL since v17.0.0	Measurement result of serving L2 U2N relay UE.
ul-PDCP-ExcessDelayResultList-r17 UL-PDCP-ExcessDelayResultList-r17 · OPTIONAL since v17.0.0
coarseLocationInfo-r17 OCTET STRING · OPTIONAL since v17.1.0	This field indicates the coarse location information reported by the UE. This field is coded as the Ellipsoid-Point defined in TS 37.355 [49]. The first/leftmost bit of the first octet contains the most significant bit. The least significant bits of degreesLatitude and degreesLongitude are set to 0 to meet the accuracy requirement corresponds to a granularity of approximately 2 km. It is up to UE implementation how many LSBs are set to 0 to meet the accuracy requirement
altitudeUE-r18 Altitude-r18 · OPTIONAL since v18.0.0
cellsMetReportOnLeaveList-r18 SEQUENCE (SIZE (1..maxCellReport)) OF PhysCellId · OPTIONAL since v18.2.0
