ATG-Config (ATG-Config-r18)
ATG-Config-r18 is an RRC information element of 3GPP TS 38.331 (38331), the 5G NR Radio Resource Control (RRC) protocol.
Definition
The IE ATG-Config provides parameters needed for the UE to access NR via ATG access.
ATG-Config-r18 ::= SEQUENCE {
atg-gNB-Location-r18 ReferenceLocation-r17 OPTIONAL, -- Need R
height-gNB-r18 INTEGER (-16384..16383) OPTIONAL, -- Need R

}Fields (4)
| Field | Description |
|---|---|
| atg-gNB-Location-r18 ReferenceLocation-r17 · OPTIONAL Need R | Indicates the BS location for ATG access. |
| height-gNB-r18 INTEGER (-16384..16383) · OPTIONAL Need R since v18.5.0 | Indicates the height of the BS for ATG access relative to the sea level. Unit in meter. |
| cellSpecificKoffset-r18 INTEGER(1..3) · OPTIONAL Need R | Scheduling offset used for the timing relationships that are modified for ATG. Unit in slot. |
| ta-ReportATG-r18 ENUMERATED {enabled} · OPTIONAL Need R | When this field is included in SIB22, it indicates reporting of timing advanced is enabled during Random Access due to RRC connection establishment or RRC connection resume, and during RRC connection reestablishment. When this field is included in ServingCellConfigCommon within dedicated signalling, it indicates TA reporting is enabled during Random Access due to reconfiguration with sync (see TS 38.321 [3], clause 5.4.8). |
