FieldDescription
cellId
PhysCellId
csi-rs-MeasurementBW
SEQUENCE {
nrofPRBs
ENUMERATED { size24, size48, size96, size192, size264}
Allowed size of the measurement BW in PRBs. See TS 38.211 [16], clause 7.4.1.
startPRB
INTEGER(0..2169)
Starting PRB index of the measurement bandwidth. See TS 38.211 [16], clause 7.4.1.
density
ENUMERATED {d1,d3} · OPTIONAL Need R
Frequency domain density for the 1-port CSI-RS for L3 mobility. See TS 38.211 [16], clause 7.4.1.
csi-rs-ResourceList-Mobility
SEQUENCE (SIZE (1..maxNrofCSI-RS-ResourcesRRM)) OF CSI-RS-Resource-Mobility
List of CSI-RS resources for mobility. The maximum number of CSI-RS resources that can be configured per measObjectNR depends on the configuration of associatedSSB and the support of increasedNumberofCSIRSPerMO capability (see TS 38.214 [19], clause 5.1.6.1.3).
