}Fields (21)
| Field | Description |
|---|---|
| csi-RS-Index CSI-RS-Index | CSI-RS resource index associated to the CSI-RS resource to be measured (and used for reporting). |
| slotConfig CHOICE { | Indicates the CSI-RS periodicity (in milliseconds) and for each periodicity the offset (in number of slots). When subcarrierSpacing is set to kHz15 , the maximum offset values for periodicities ms4/ms5/ms10/ms20/ms40 are 3/4/9/19/39 slots. When subcarrierSpacing is set to kHz30 , the maximum offset values for periodicities ms4/ms5/ms10/ms20/ms40 are 7/9/19/39/79 slots. When subcarrierSpacing is set to kHz60 , the maximum offset values for periodicities ms4/ms5/ms10/ms20/ms40 are 15/19/39/79/159 slots. When subcarrierSpacing is set kHz120 , the maximum offset values for periodicities ms4/ms5/ms10/ms20/ms40 are 31/39/79/159/319 slots. When subcarrierSpacing is set to kHz480 , the maximum offset values for periodicities ms4/ms5/ms10/ms20/ms40 are 127/159/319/639/1279 slots. When subcarrierSpacing is set to kHz960 , the maximum offset values for periodicities ms4/ms5/ms10/ms20/ms40 are 255/319/639/1279/2559 slots. If slotConfig-r17 is present, UE shall ignore the slotConfig (without suffix). |
| ms4 INTEGER (0..31) | |

| ms10 INTEGER (0..79) | |
| ms20 INTEGER (0..159) | |
| ms40 INTEGER (0..319) | |
| associatedSSB SEQUENCE { · OPTIONAL Need R | If this field is present, the UE may base the timing of the CSI-RS resource indicated in CSI-RS-Resource-Mobility on the timing of the cell indicated by the cellId in the CSI-RS-CellMobility . In this case, the UE is not required to monitor that CSI-RS resource if the UE cannot detect the SS/PBCH block indicated by this associatedSSB and cellId . If this field is absent, the UE shall base the timing of the CSI-RS resource indicated in CSI-RS-Resource-Mobility on the timing of the serving cell indicated by refServCellIndex . In this case, the UE is required to measure the CSI-RS resource even if SS/PBCH block(s) with cellId in the CSI-RS-CellMobility are not detected. CSI-RS resources with and without associatedSSB may be configured in accordance with the rules in TS 38.214 [19], clause 5.1.6.1.3. |
| ssb-Index SSB-Index | |
| isQuasiColocated BOOLEAN | Indicates that the CSI-RS resource is quasi co-located with the associated SS/PBCH block, see TS 38.214 [19], clause 5.1.6.1.3. |
| frequencyDomainAllocation CHOICE { | Frequency domain allocation within a physical resource block in accordance with TS 38.211 [16], clause 7.4.1.5.3 including table 7.4.1.5.2-1. The number of bits that may be set to one depend on the chosen row in that table. |
| row1 BIT STRING (SIZE (4)) | |
| row2 BIT STRING (SIZE (12)) | |
| firstOFDMSymbolInTimeDomain INTEGER (0..13) | Time domain allocation within a physical resource block. The field indicates the first OFDM symbol in the PRB used for CSI-RS, see TS 38.211 [16], clause 7.4.1.5.3. |
| sequenceGenerationConfig INTEGER (0..1023) | Scrambling ID for CSI-RS (see TS 38.211 [16], clause 7.4.1.5.2). |
| slotConfig-r17 CHOICE { · OPTIONAL Need R since v17.2.0 | Indicates the CSI-RS periodicity (in milliseconds) and for each periodicity the offset (in number of slots). When subcarrierSpacing is set to kHz15 , the maximum offset values for periodicities ms4/ms5/ms10/ms20/ms40 are 3/4/9/19/39 slots. When subcarrierSpacing is set to kHz30 , the maximum offset values for periodicities ms4/ms5/ms10/ms20/ms40 are 7/9/19/39/79 slots. When subcarrierSpacing is set to kHz60 , the maximum offset values for periodicities ms4/ms5/ms10/ms20/ms40 are 15/19/39/79/159 slots. When subcarrierSpacing is set kHz120 , the maximum offset values for periodicities ms4/ms5/ms10/ms20/ms40 are 31/39/79/159/319 slots. When subcarrierSpacing is set to kHz480 , the maximum offset values for periodicities ms4/ms5/ms10/ms20/ms40 are 127/159/319/639/1279 slots. When subcarrierSpacing is set to kHz960 , the maximum offset values for periodicities ms4/ms5/ms10/ms20/ms40 are 255/319/639/1279/2559 slots. If slotConfig-r17 is present, UE shall ignore the slotConfig (without suffix). |
