LocationMeasurementInfo field descriptions
carrierFreq The EARFCN value of the carrier received from upper layers for which the UE needs to perform the inter-RAT RSTD measurements.
measPRS-Offset Indicates the requested gap offset for performing RSTD measurements towards E-UTRA. It is the smallest subframe offset from the beginning of subframe 0 of SFN=0 of the serving cell of the requested gap for measuring PRS positioning occasions in the carrier frequency carrierFreq for which the UE needs to perform the inter-RAT RSTD measurements. The PRS positioning occasion information is received from upper layers. The value of measPRS-Offset is obtained by mapping the starting subframe of the PRS positioning occasion in the measured cell onto the corresponding subframe in the serving cell and is calculated as the serving cell's number of subframes from SFN=0 mod 40. The UE shall take into account any additional time required by the UE to start PRS measurements on the other carrier when it does this mapping for determining the measPRS-Offset. NOTE: Figure 6.2.2-1 in TS 36.331 illustrates the measPRS-Offset field.

MAC-CellGroupConfig field descriptions
allowCSI-SRS-Tx-MulticastDRX-Active Used to control the CSI/SRS transmission during MBS multicast DRX ActiveTime, see TS 38.321.
csi-Mask If set to true, the UE limits CSI reports to the on-duration period of the DRX cycle, see TS 38.321.
dataInactivityTimer Releases the RRC connection upon data inactivity as specified in clause 5.3.8.5 and in TS 38.321. Value s1 corresponds to 1 second, value s2 corresponds to 2 seconds, and so on.
drx-Config, drx-ConfigExt Used to configure DRX as specified in TS 38.321. Network only configures drx-ConfigExt when drx-Config is configured.
drx-ConfigSecondaryGroup Used to configure DRX related parameters for the second DRX group as specified in TS 38.321. The network does not configure secondary DRX group with DCP simultaneously nor secondary DRX group with a dormant BWP simultaneously.
drx-ConfigSL Used to configure additional DRX parameters for the UE performing sidelink operation with resource allocation mode 1, as specified in TS 38.321. Network only configures this field if sl-ScheduledConfig is configured and drx-Config is configured.
drx-LastTransmissionUL If this field is present, the start of the drx-HARQ-RTT-TimerUL is after the last transmission within a bundle, see TS 38.321.
g-RNTI-ConfigToAddModList List of G-RNTI configurations to add or modify. Up to 8 G-RNTIs can be configured in total in this release based on the UE capability.
g-RNTI-ConfigToReleaseList List of G-RNTI configurations to release.
g-CS-RNTI-ConfigToAddModList List of G-CS-RNTI configurations to add or modify. Up to 8 G-CS-RNTIs can be configured in total in this release based on the UE capability.
g-CS-RNTI-ConfigToReleaseList List of G-CS-RNTI configurations to release.
intraCG-Prioritization Used to enable HARQ process ID selection based on LCH-priority for one CG as specified in TS 38.321.
lch-BasedPrioritization If this field is present, the corresponding MAC entity of the UE is configured with prioritization between overlapping grants and between scheduling request and overlapping grants based on LCH priority, see TS 38.321. The network does not configure lch-BasedPrioritization with enhancedSkipUplinkTxDynamic simultaneously nor lch-BasedPrioritization with enhancedSkipUplinkTxConfigured simultaneously.
posMG-Request Indicates whether UE is configured to send UL MAC CE for Positioning Measurement Gap Activation/Deactivation Request, as specified in TS 38.321.
schedulingRequestID-BFR-SCell Indicates the scheduling request configuration applicable for BFR on SCell, as specified in TS 38.321.
schedulingRequestID-BFR Indicates the scheduling request configuration (SchedulingRequestConfig) that the UE shall use upon detecting a beam failure on the detection resources configured in failureDetectionSet1 of a serving cell while beam failure is not detected on resources configured in failureDetectionSet2 of the same serving cell.
schedulingRequestID-BFR2 Indicates the scheduling request configuration (SchedulingRequestConfig) that the UE shall use upon detecting a beam failure on the detection resources configured in failureDetectionSet2 of a serving cell while beam failure is not detected on resources configured in failureDetectionSet1 of the same serving cell.
schedulingRequestID-LBT-SCell Indicates the scheduling request configuration applicable for consistent uplink LBT recovery on SCell, as specified in TS 38.321.
schedulingRequestID-PosMG-Requestm Indicates the scheduling request configuration applicable for Positioning Measurement Gap Activation/Deactivation Request, as specified in TS 38.321.
skipUplinkTxDynamic, enhancedSkipUplinkTxDynamic, enhancedSkipUplinkTxConfigured If set to true, the UE skips UL transmissions as described in TS 38.321. If the UE is configured with enhancedSkipUplinkTxDynamic or enhancedSkipUplinkTxConfigured with value true, REPETITION_NUMBER (as specified in clause 5.4.2.1 of TS 38.321) of the corresponding PUSCH transmission of the uplink grant shall be equal to 1.
tag-Config The field is used to configure parameters for a time-alignment group. The field is not present if any DAPS bearer is configured.
usePreBSR If set to true, the MAC entity of the IAB-MT may use the Pre-emptive BSR, see TS 38.321.

MBS-RNTI-SpecificConfig field descriptions
drx-ConfigPTM Used to configure DRX for PTM transmission as specified in TS 38.321.
g-CS-RNTI Used to scramble the SPS group-common PDSCH and activation/deactivation of SPS group-common PDSCH for one or more MBS multicast services.
g-RNTI Used to scramble the scheduling and transmission of PTM for one or more MBS multicast services.
groupCommon-RNTI Used to configure g-RNTI or g-CS-RNTI.
harq-FeedbackEnablerMulticast Indicates whether the UE shall provide HARQ feedback for MBS multicast. Value dci-enabler means that whether the UE shall provide HARQ feedback for MBS multicast is indicated by DCI as specified in TS 38.213. Value enabled means the UE shall always provide HARQ feedback for MBS multicast. When the field is absent, the UE does not provide HARQ feedback for MBS multicast (see clause 18 of TS 38.213).
harq-FeedbackOptionMulticast Indicates the feedback mode for MBS multicast dynamically scheduled PDSCH or SPS PDSCH.
mbs-RNTI-SpecificConfigId An identifier of the RNTI specific configuration for MBS multicast.
pdsch-AggregationFactor Number of repetitions for dynamically scheduled MBS multicast data (see clause 5.1.2.1 of TS 38.214). When the field is absent and groupCommon-RNTI is set to g-RNTI, the UE applies the value 1.

Conditional Presence	Explanation
G-RNTI	This field is optionally present, Need S, if groupCommon-RNTI is set to g-RNTI. The field is absent when groupCommon-RNTI is set to g-CS-RNTI.
HARQFeedback	The field is mandatory present when harq-FeedbackEnablerMulticast is present. It is absent otherwise.
MCG-Only	This field is optionally present, Need M, for the MAC-CellGroupConfig of the MCG. It is absent otherwise.
LCH-PrioWithReTxTimer	This field is optionally present, Need R, if lch-BasedPrioritization-r16 is configured in this MAC entity and cg-RetransmissionTimer-r16 is configured for any configured grant configuration associated with this MAC entity. It is absent otherwise, Need R.
