Fields (9)
| Field | Description |
|---|---|
| plmn-IdentityList SEQUENCE (SIZE (1..maxPLMN)) OF PLMN-Identity since v15.3.0 | |
| trackingAreaCode TrackingAreaCode · OPTIONAL Need R since v15.3.0 | Indicates Tracking Area Code to which the cell indicated by cellIdentity field belongs. The absence of the field indicates that the cell only supports PSCell/SCell functionality (per PLMN) or is an NTN cell. |
| ranac RAN-AreaCode · OPTIONAL Need R since v15.3.0 | |
| cellIdentity CellIdentity since v15.3.0 | |
| cellReservedForOperatorUse ENUMERATED {reserved, notReserved} | Indicates whether the cell is reserved for operator use (per PLMN), as defined in TS 38.304 [20]. This field is ignored by IAB-MT and NCR-MT. |
| iab-Support-r16 ENUMERATED {true} · OPTIONAL Need S since v16.0.0 | This field combines both the support of IAB and the cell status for IAB. If the field is present, the cell supports IAB and the cell is also considered as a candidate for cell (re)selection for IAB-node; if the field is absent, the cell does not support IAB and/or the cell is barred for IAB-node. This field is absent if mobileIAB-Cell is broadcasted in the cell. |
| trackingAreaList-r17 SEQUENCE (SIZE (1..maxTAC-r17)) OF TrackingAreaCode · OPTIONAL Need R since v17.0.0 | List of Tracking Areas to which the cell indicated by cellIdentity field belongs. If this field is present, network does not configure trackingAreaCode. Total number of different TACs across different PLMN-IdentityInfo s shall not exceed maxTAC . This field is only present in an NTN cell. |
| gNB-ID-Length-r17 INTEGER (22..32) · OPTIONAL Cond eventID-TSS since v17.1.0 | Indicates the length of the gNB ID out of the 36-bit long cellIdentity . This field is always present if the mobileIAB-Support is broadcasted. |
| mobileIAB-Support-r18 ENUMERATED {true} · OPTIONAL Need S since v18.0.0 | This field indicates the support of mobile IAB and whether the cell can be considered as a candidate for cell (re)selection for mobile IAB-node. This field is absent if mobileIAB-Cell is broadcasted in the cell. If the field is absent, the cell is barred for mobile IAB-node. |
