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 TS 38.211, clause 7.4.3.1), this field corresponds to k_SSB, and k_SSB is obtained from k_SSB (see TS 38.211 [16], clause 7.4.3.1); the LSB of this field is used also for deriving the QCL relation between SS/PBCH blocks as specified in TS 38.213 [13], clause 4.1.TS 37.213), this field corresponds to k_SSB, and k_SSB is obtained from k_SSB (see TS 38.211, clause 7.4.3.1, clause 4.1.TS 38.213, clause 4.1. 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).

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 TS 38.213, clause 4.1.

Value rna indicates that ROHC header compression continues when the UE resumes for SDT in a cell belonging to the same RNA as the PCell where the RRCRelease message was received. If the field is absent, the UE releases any stored value for this field and the PDCP entity of the radio bearers configured for SDT always resets the ROHC header compression protocol during PDCP re-establishment when SDT procedure is initiated, as specified in TS 38.323.

Indicates the ID(s) of the DRB(s) that are configured for SDT. If size of the sequence is zero, then the UE assumes that none of the DRBs are configured for SDT. The network only configures MN terminated MCG bearers for SDT.

Indiates whether SRB2 is configured for SDT or not.

Downlink BWP configuration for CG-SDT. If a UE is a RedCap UE and if the initialDownlinkBWP-RedCap is configured in downlinkConfigCommon in SIB1, this field is configured for initialDownlinkBWP-RedCap, otherwise it is configured for initialDownlinkBWP.

UL BWP configuration for CG-SDT on NUL carrier. If a UE is a RedCap UE and if the initialUplinkBWP-RedCap is configured in uplinkConfigCommon in SIB1, this field is configured for initialUplinkBWP-RedCap, otherwise it is configured for initialUplinkBWP for NUL.

UL BWP configuration for CG-SDT on SUL carrier configured for the initialUplinkBWP for SUL.

The CS-RNTI value for CG-SDT as specified in TS 38.321.

An RSRP threshold configured for SSB selection for CG-SDT as specified in TS 38.321.

Configuration for the RSRP based TA validation. If this field is not configured, then the UE does not perform RSRP based TA validation.

TAT value for CG-SDT as specified in TS 38.321. The network always configures this field when sdt-MAC-PHY-CG-Config is configured.

The RSRP threshold for TA validation for CG-SDT as specified in TS 38.321. Value dB2 corresponds to 2 dB, value dB4 corresponds to 4 dB and so on.

BWP configuration for SRS for Positioning during the RRC_INACTIVE state in Normal Uplink Carrier. If the field is absent UE is configured with an SRS for Positioning associated with the initial UL BWP and transmitted, during the RRC_INACTIVE state, inside the initial UL BWP with the same CP and SCS as configured for initial UL BWP.

BWP configuration for SRS for Positioning during the RRC_INACTIVE state in Supplementary Uplink Carrier. If the field is absent UE is configured with an SRS for Positioning associated with the initial UL BWP and transmitted, during the RRC_INACTIVE state, inside the initial UL BWP with the same CP and SCS as configured for initial UL BWP.

RSRP threshold for the increase/decrease of RSRP for time alignment validation as specified in TS 38.321.

TAT value for SRS for positioning transmission during RRC_INACTIVE state as specified in TS 38.321. The network always configures this field when srs-PosRRC-Inactive is configured.

SRS for Positioning configuration in RRC_INACTIVE state in Normal Uplink Carrier.

SRS for Positioning configuration in RRC_INACTIVE state in Supplementary Uplink Carrier.

The extended DRX (eDRX) cycle for RAN-initiated paging to be applied by the UE. Value rf256 corresponds to 256 radio frames, value rf512 corresponds to 512 radio frames and so on. Value of the field indicates an eDRX cycle which is shorter or equal to the IDLE mode eDRX cycle configured for the UE.

Network ensures that the UE in RRC_INACTIVE always has a valid ran-NotificationAreaInfo.

Refers to the UE specific cycle for RAN-initiated paging. Value rf32 corresponds to 32 radio frames, value rf64 corresponds to 64 radio frames and so on.

Indicates the C-RNTI to the L2 U2N Remote UE.

Refers to the timer that triggers the periodic RNAU procedure in UE. Value min5 corresponds to 5 minutes, value min10 corresponds to 10 minutes and so on.
