}Fields (10)
| Field | Description |
|---|---|
| csi-IM-ResourceId CSI-IM-ResourceId | |
| csi-IM-ResourceElementPattern CHOICE { · OPTIONAL Need M | The resource element pattern (Pattern0 (2,2) or Pattern1 (4,1)) with corresponding parameters (see TS 38.214 [19], clause 5.2.2.4) |
| pattern0 SEQUENCE { | |
| subcarrierLocation-p0 ENUMERATED { s0, s2, s4, s6, s8, s10 } | OFDM subcarrier occupancy of the CSI-IM resource for Pattern0 (see TS 38.214 [19], clause 5.2.2.4) |
| symbolLocation-p0 INTEGER (0..12) | OFDM symbol location of the CSI-IM resource for Pattern0 (see TS 38.214 [19], clause 5.2.2.4) |
| pattern1 SEQUENCE { | |
| subcarrierLocation-p1 ENUMERATED { s0, s4, s8 } | OFDM subcarrier occupancy of the CSI-IM resource for Pattern1 (see TS 38.214 [19], clause 5.2.2.4) |
| symbolLocation-p1 INTEGER (0..13) | OFDM symbol location of the CSI-IM resource for Pattern1 (see TS 38.214 [19], clause 5.2.2.4) |
| freqBand CSI-FrequencyOccupation · OPTIONAL Need M | Frequency-occupancy of CSI-IM (see TS 38.214 [19], clause 5.2.2.4) |
| periodicityAndOffset CSI-ResourcePeriodicityAndOffset · OPTIONAL Cond PeriodicOrSemiPersistent | Periodicity and slot offset for periodic/semi-persistent CSI-IM. Network always configures the UE with a value for this field for periodic and semi-persistent CSI-IM-Resources (as indicated in CSI-ResourceConfig). A change of configuration between periodic or semi-persistent and aperiodic for a CSI-IM-Resource is not supported without a release and add. |
