Provides the configuration of each MBS session provided by MBS broadcast in the current cell.

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.

Otherwise the field is absent.

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 multicast services signalled in mbs-SessionInfoList in the MBSMulticastConfiguration 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 multicast 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 multicast 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 multicast services in the neighbouring cells, i.e. the UE cannot determine the presence or absence of an MBS multicast service in neighbouring cells based on the absence of this field.

The field contains the RAN visible application layer measurement report.

The field indicates a list of application layer buffer levels, and each AppLayerBufferLevel indicates the application layer buffer level in ms. Value 0 corresponds to 0ms, value 1 corresponds to 10ms, value 2 corresponds to 20 ms and so on. If the buffer level is larger than the maximum value of 30000 (5 minutes), the UE reports 30000.

Indicates the application layer playout delay for media start-up in ms. Value 0 corresponds to 0ms, value 1 corresponds to 1ms, value 2 corresponds to 2 ms and so on. If the playout delay for media start-up is larger than the maximum value of 30000ms, the UE reports 30000.

If pdu-SessionIdList-r18 is present, it contains the same number of entries, listed in the same order as in pdu-SessionIdList-r17.

Value barred means that the cell is barred, as defined in TS 38.304. This field is ignored by IAB-MT and NCR-MT. This field is ignored for connectivity to NTN or ATG.

Controls cell selection/reselection to intra-frequency cells when the highest ranked cell is barred, or treated as barred by the UE, as specified in TS 38.304. This field is ignored by IAB-MT and NCR-MT.

Determines a common ControlResourceSet (CORESET), a common search space and necessary PDCCH parameters. If the field ssb-SubcarrierOffset indicates that SIB1 is absent, the field pdcch-ConfigSIB1 indicates the frequency positions where the UE may find SS/PBCH block with SIB1 or the frequency range where the network does not provide SS/PBCH block with SIB1 (see clause 13 of TS 38.213).

Corresponds to kSSB (see TS 38.213), which is the frequency domain offset between SSB and the overall resource block grid in number of subcarriers. (See clause 7.4.3.1 of TS 38.211). For operation with shared spectrum channel access in FR1 (see TS 37.213), this field corresponds to k_SSB, and k_SSB is obtained from k_SSB (see clause 7.4.3.1 of TS 38.211); the LSB of this field is used also for deriving the QCL relation between SS/PBCH blocks as specified in clause 4.1 ofTS 38.213. The value range of this field may be extended by an additional most significant bit encoded within PBCH as specified in TS 38.213. This field may indicate that this cell does not provide SIB1 and that there is hence no CORESET#0 configured in MIB (see clause 13 of TS 38.213). In this case, the field pdcch-ConfigSIB1 may indicate the frequency positions where the UE may (not) find a SS/PBCH with a control resource set and search space for SIB1 (see clause 13 of TS 38.213).

Subcarrier spacing for SIB1, Msg.2/4 and MsgB for initial access, paging and broadcast SI-messages. If the UE acquires this MIB on an FR1 carrier frequency, the value scs15or60 corresponds to 15 kHz and the value scs30or120 corresponds to 30 kHz. If the UE acquires this MIB on an FR2 carrier frequency, the value scs15or60 corresponds to 60 kHz and the value scs30or120 corresponds to 120 kHz. For operation with shared spectrum channel access in FR1 (see TS 37.213) and for operation in FR2-2, the subcarrier spacing for SIB1, Msg.2/4 and MsgB for initial access, paging and broadcast SI-messages is same as that for the corresponding SSB. For operation with shared spectrum channel access, this field instead is used for deriving the QCL relation between SS/PBCH blocks as specified in clause 4.1 of TS 38.213.

The 6 most significant bits (MSB) of the 10-bit System Frame Number (SFN). The 4 LSB of the SFN are conveyed in the PBCH transport block as part of channel coding (i.e. outside the MIB encoding), as defined in clause 7.1 in TS 38.212.

If targetRAT-Type is eutra, this field is used to deliver the key synchronisation and Key freshness for the NR to LTE/EPC handovers and a part of the downlink NAS COUNT as specified in TS 33.501 and the content of the parameter is defined in TS 24.501. If targetRAT-Type is utra-fdd, this field is used to deliver the key synchronisation and Key freshness for the NR to FDD UTRAN handover and a part of the downlink NAS COUNT as specified in TS 33.501 and the content of the parameter is defined in TS 24.501.

The field contains a message specified in another standard, as indicated by the targetRAT-Type, and carries information about the target cell identifier(s) and radio parameters relevant for the target radio access technology. A complete message is included, as specified in the other standard. See NOTE 1

Indicates the target RAT type.

Indicates the handover is triggered by EPS fallback for IMS voice as specified in TS 23.502.

Indicates whether the Paging message is originated due to the PDU sessions from the non-3GPP access.

Indicates whether the UE with a valid PTM configuration for a TMGI in the PagingGroupList stays in RRC_INACTIVE to receive the corresponding MBS multicast session.

Mobile Terminated SDT indication. The network includes mt-SDT indication in paging message only if the UE's I-RNTI is included in the paging message.

If the network includes pagingRecordList-v1700, it includes the same number of entries, and listed in the same order, as in pagingRecordList (i.e. without suffix). If the network includes pagingRecordList-v1800, it includes the same number of entries, and listed in the same order, as in pagingRecordList (i.e. without suffix).

Indicates whether the Paging message is originated due to IMS voice. If this field is present, it implies that the corresponding paging entry is for IMS voice. If upper layers indicate the support of paging cause and if this field is not present but pagingRecordList-v1700 is present, it implies that the corresponding paging entry is for a service other than IMS voice. Otherwise, paging cause is undetermined.

If the network includes pagingGroupList-v1800, it includes the same number of elements, and listed in the same order, as in pagingGroupList-r17. The first element corresponds to the first TMGI in pagingGroupList-r17. The second element corresponds to the second TMGI in pagingGroupList-r17, and so on.

Contains dedicated configurations used for L2 U2N relay related operation. The network configures only the SRAP configuration for local UE ID.
