numberOfMsg3-RepetitionsList
The number of repetitions for PUSCH transmission scheduled by RAR UL grant and DCI format 0_0 with CRC scrambled by TC-RNTI. This field is only applicable when the UE selects Random Access resources indicating Msg3 repetition in this BWP. If this field is absent when the set(s) of Random Access resources with MSG3 repetition indication are configured in the BWP-UplinkCommon, the UE shall apply the values {n1, n2, n3, n4} (see TS 38.214, clause 6.1.2.1).
pucch-ConfigCommon
Cell specific parameters for the PUCCH of this BWP.
pusch-ConfigCommon
Cell specific parameters for the PUSCH of this BWP.
rach-ConfigCommon
Configuration of cell specific random access parameters which the UE uses for contention based and contention free random access as well as for contention based beam failure recovery in this BWP. The NW configures SSB-based RA (and hence RACH-ConfigCommon) only for UL BWPs if the linked DL BWPs (same bwp-Id as UL-BWP) are the initial DL BWPs or DL BWPs containing the SSB associated to the initial DL BWP or for RedCap UEs DL BWPs associated with nonCellDefiningSSB or the RedCap-specific initial downlink BWP. The network configures rach-ConfigCommon, whenever it configures contention free random access (for reconfiguration with sync or for beam failure recovery).
rach-ConfigCommonIAB
Configuration of cell specific random access parameters for the IAB-MT. The IAB specific IAB RACH configuration is used by IAB-MT, if configured.
rsrp-ThresholdMsg3
Threshold used by the UE for determining whether to select resources indicating Msg3 repetition in this BWP, as specified in TS 38.321. The field is mandatory if both set(s) of Random Access resources with MSG3 repetition indication and set(s) of Random Access resources without MSG3 repetition indication are configured in the BWP. It is absent otherwise.
useInterlacePUCCH-PUSCH
If the field is present, the UE uses uplink frequency domain resource allocation Type 2 for cell-specific PUSCH, e.g., PUSCH scheduled by RAR UL grant (see TS 38.213, clause 8.3.2.2) and uses interlaced PUCCH Format 0 and 1 for cell-specific PUCCH (see TS 38.213 [13], clause 9.2.1).TS 38.214, clause 6.1.2.2TS 38.213, clause 9.2.1).
Conditional Presence Explanation
Msg3RepThis field is optionally present, Need S, if the set(s) of Random Access resources with MSG3 repetition indication are configured in the BWP-UplinkCommon. It is absent otherwise.
RA-PrioSliceAIThe field is optionally present in SIB1, Need R, if both parameters ra-PrioritizationForAccessIdentity and the ra-PrioritizationForSlicing/ra-PrioritizationForSlicingTwoStep are present in SIB1. It is absent otherwise.
SpCellOnly2The field is optionally present, Need M, in the BWP-UplinkCommon of an SpCell. It is absent otherwise.

 –  BWP-UplinkDedicatedp. 512

The IE BWP-UplinkDedicated is used to configure the dedicated (UE specific) parameters of an uplink BWP.
BWP-UplinkDedicated information element
BWP-UplinkDedicated field descriptions
beamFailureRecoveryConfig
Configuration of beam failure recovery. If supplementaryUplink is present, the field is present only in one of the uplink carriers, either UL or SUL.
configuredGrantConfig
A Configured-Grant of type1 or type2. It may be configured for UL or SUL but in case of type1 not for both at a time. Except for reconfiguration with sync, the NW does not reconfigure configuredGrantConfig when there is an active configured uplink grant Type 2 (see TS 38.321). However, the NW may release the configuredGrantConfig at any time. Network can only configure configured grant in one BWP using either this field or configuredGrantConfigToAddModList.
configuredGrantConfigToAddModList
Indicates a list of one or more configured grant configurations to be added or modified for one BWP. Except for reconfiguration with sync, the NW does not reconfigure a Type 2 configured grant configuration when it is active (see TS 38.321). The network configures multiple CG configurations for one BWP with either all configurations or no configuration configured with cg-RetransmissionTimer-r16.
configuredGrantConfigToReleaseList
Indicates a list of one or more UL Configured Grant configurations to be released. The NW may release a configured grant configuration at any time.
configuredGrantConfigType2DeactivationStateList
Indicates a list of the deactivation states in which each state can be mapped to a single or multiple Configured Grant type 2 configurations to be deactivated when the corresponding deactivation DCI is received, see clause 7.3.1 in TS 38.212 and clause 10.2 in TS 38.213.
cp-ExtensionC2, cp-ExtensionC3
Configures the cyclic prefix (CP) extension (see TS 38.211, clause 5.3.1). For 15 kHz SCS, {1..28} are valid for both cp-ExtensionC2 and cp-ExtensionC3. For 30 kHz SCS, {1..28} are valid for cp-ExtensionC2 and {2..28} are valid for cp-ExtensionC3. For 60 kHz SCS, {2..28} are valid for cp-ExtensionC2 and {3..28} are valid for cp-ExtensionC3.
lbt-FailureRecoveryConfig
Configures parameters used for detection of consistent uplink LBT failures for operation with shared spectrum channel access, as specified in TS 38.321.
pathlossReferenceRSToAddModList
A list of Reference Signals (e.g. a CSI-RS config or a SS block) to be used for path loss estimation for PUSCH, PUCCH and SRS for unified TCI state operation. If unifiedTCI-StateType is not configured for the serving cell, no element in this list is configured.
pucch-Config
PUCCH configuration for one BWP of the normal UL or SUL of a serving cell. If the UE is configured with SUL, the network configures PUCCH only on the BWPs of one of the uplinks (normal UL or SUL). The network configures PUCCH-Config at least on non-initial BWP(s) for SpCell and PUCCH SCell. If supported by the UE, the network may configure at most one additional SCell of a cell group with PUCCH-Config (i.e. PUCCH SCell). If PUCCH cell switching is supported by the UE, the network may configure two TDD serving cells with PUCCH-Config within each PUCCH group. For supporting PUCCH cell switching in the PUCCH group with the SpCell, the TDD SpCell and one TDD SCell shall have PUCCH-Config on their normal UL. For supporting PUCCH cell switching in the PUCCH group with only SCells, two TDD SCells shall have PUCCH-Config on their normal UL.
In (NG)EN-DC and NE-DC, the NW configures at most one serving cell per frequency range with PUCCH. In (NG)EN-DC and NE-DC, if two PUCCH groups are configured, the serving cells of the NR PUCCH group in FR2 use the same numerology. For NR-DC, the maximum number of PUCCH groups in each cell group is one, and only the same numerology is supported for the cell group with carriers only in FR2.
The NW may configure PUCCH for a BWP when setting up the BWP. The network may also add/remove the pucch-Config in an RRCReconfiguration with reconfigurationWithSync (for SpCell or PUCCH SCell) or with SCell release and add (for PUCCH SCell) to move the PUCCH between the UL and SUL carrier of one serving cell. In other cases, only modifications of a previously configured pucch-Config are allowed. If one (S)UL BWP of a serving cell is configured with PUCCH, all other (S)UL BWPs must be configured with \break:10 PUCCH, too.
pucch-ConfigurationList
PUCCH configurations for two simultaneously constructed HARQ-ACK codebooks (see TS 38.213, clause 9.1). Different PUCCH Resource IDs are configured in different PUCCH-Config within the pucch-ConfigurationList if configured.
pucch-ConfigurationListMulticast1
PUCCH configurations for two simultaneously constructed HARQ-ACK codebooks for MBS multicast (see TS 38.213, clause 9).
pucch-ConfigurationListMulticast2
PUCCH configurations for two simultaneously constructed NACK-only feedback for MBS multicast (see TS 38.213, clause 9).
pusch-Config
PUSCH configuration for one BWP of the normal UL or SUL of a serving cell. If the UE is configured with SUL and if it has a PUSCH-Config for both UL and SUL, an UL/SUL indicator field in DCI indicates which of the two to use. See TS 38.212, clause 7.3.1.
pucch-ConfigMulticast1
PUCCH configuration for the HARQ-ACK codebook for MBS multicast when multicast feedback is not configured with a priority value (see TS 38.213, clause 9). If the field is not configured, pucch-Config applies.
pucch-ConfigMulticast2
PUCCH configuration for the NACK-only feedback for MBS multicast when multicast feedback is not configured with a priority value (see TS 38.213, clause 9). If the field is not configured, pucch-Config applies.

Indicates the UE specific PUCCH configurations used for the HARQ-ACK feedback reporting for NR sidelink communication.
srs-Config
Uplink sounding reference signal configuration.
ul-powerControl
Configures power control parameters for PUCCH, PUSCH and SRS when UE is configured with unifiedTCI-StateType for this serving cell. For each serving cell, ul-powerControl is either configured in all BWP-UplinkDedicated or it is not configured in any BWP-UplinkDedicated. When unifiedTCI-StateRef in the BWP-UplinkDedicated of a serving cell refers to another serving cell, ul-powerControl is either configured in all BWP-UplinkDedicated of these two serving cells or it is not configured in any BWP-UplinkDedicated of these two serving cells.
