Fields of MBSBroadcastConfiguration-r17-IEs (7)
| Field | Description |
|---|---|
| mbs-SessionInfoList-r17 MBS-SessionInfoList-r17 · OPTIONAL Need R | Provides the configuration of each MBS session provided by MBS broadcast in the current cell. If mbs-SessionInfoList-v1900 is present, it includes the same number of entries listed in the same order as in mbs-SessionInfoList-r17 . The first element in mbs-SessionInfoList-v1900 corresponds to the first MBS broadcast service in mbs-SessionInfoList-r17 . |
| mbs-NeighbourCellList-r17 MBS-NeighbourCellList-r17 · OPTIONAL Need S | List of neighbour cells providing one or more MBS broadcast services via broadcast MRB that are provided by the current cell. This field is used by the UE together with mtch-NeighbourCell field signalled for each MBS session in the corresponding MBS-SessionInfo . When an empty mbs-NeighbourCellList list is signalled, the UE shall assume that MBS broadcast services signalled in mbs-SessionInfoList in the MBSBroadcastConfiguration message are not provided in any neighbour cell. When a non-empty mbs-NeighbourCellList is signalled, the current serving cell does not provide information about MBS broadcast services of a neighbour cell that is not included in mbs-NeighbourCellList , i.e., the UE cannot determine the presence or absence of an MBS service of a neighbour cell that is absent. When the field mbs-NeighbourCellList is absent, the current serving cell does not provide information about MBS broadcast services in the neighbouring cells, i.e. the UE cannot determine the presence or absence of an MBS service in neighbouring cells based on the absence of this field. |
| drx-ConfigPTM-List-r17 SEQUENCE (SIZE (1..maxNrofDRX-ConfigPTM-r17)) OF DRX-ConfigPTM-r17 · OPTIONAL Need R | |
| pdsch-ConfigMTCH-r17 PDSCH-ConfigBroadcast-r17 · OPTIONAL Need S | Provides parameters for acquiring the PDSCH for MTCH. When this field is absent, the UE shall use parameters in pdsch-ConfigMCCH to acquire the PDSCH for MTCH. |
| mtch-SSB-MappingWindowList-r17 MTCH-SSB-MappingWindowList-r17 · OPTIONAL Need R | |
| lateNonCriticalExtension OCTET STRING · OPTIONAL | |

| Field | Description |
|---|---|
| mbs-SessionInfoList-v1900 MBS-SessionInfoList-v1900 · OPTIONAL Need R since v19.0.0 | Provides the configuration of each MBS session provided by MBS broadcast in the current cell. If mbs-SessionInfoList-v1900 is present, it includes the same number of entries listed in the same order as in mbs-SessionInfoList-r17 . The first element in mbs-SessionInfoList-v1900 corresponds to the first MBS broadcast service in mbs-SessionInfoList-r17 . |
