Fields (10)

Field	Description
tpc-Accumulation ENUMERATED { disabled } · OPTIONAL Need S	If enabled, UE applies TPC commands via accumulation. If not enabled, UE applies the TPC command without accumulation. If the field is absent, TPC accumulation is enabled (see TS 38.213 [13], clause 7.1).
msg3-Alpha Alpha · OPTIONAL Need S	Dedicated alpha value for msg3 PUSCH (see TS 38.213 [13], clause 7.1). When the field is absent the UE applies the value 1.
p0-NominalWithoutGrant INTEGER (-202..24) · OPTIONAL Need M	P0 value for UL grant-free/SPS based PUSCH. Value in dBm. Only even values (step size 2) allowed (see TS 38.213 [13], clause 7.1).
p0-AlphaSets SEQUENCE (SIZE (1..maxNrofP0-PUSCH-AlphaSets)) OF P0-PUSCH-AlphaSet · OPTIONAL Need M	Configuration {p0-pusch, alpha} sets for PUSCH (except msg3 and msgA PUSCH), i.e., { {p0,alpha,index1}, {p0,alpha,index2},...} (see TS 38.213 [13], clause 7.1). When no set is configured, the UE uses the P0-nominal for msg3/msgA PUSCH, P0-UE is set to 0 and alpha is set according to either msg3-Alpha or msgA-Alpha (see TS 38.213 [13], clause 7.1). This field is not configured if unifiedTCI-StateType is configured for the serving cell.
pathlossReferenceRSToAddModList SEQUENCE (SIZE (1..maxNrofPUSCH-PathlossReferenceRSs)) OF PUSCH-PathlossReferenceRS · OPTIONAL Need N	A set of Reference Signals (e.g. a CSI-RS config or a SS block) to be used for PUSCH path loss estimation. The set consists of Reference Signals configured using pathLossReferenceRSToAddModList and Reference Signals configured using pathlossReferenceRSToAddModListSizeExt . Up to maxNrofPUSCH-PathlossReferenceRSs may be configured (see TS 38.213 [13], clause 7.1). No elements in the list pathLossReferenceRSToAddModList nor pathlossReferenceRSToAddModListSizeExt are configured if unifiedTCI-StateType is configured for the serving cell.
pathlossReferenceRSToReleaseList SEQUENCE (SIZE (1..maxNrofPUSCH-PathlossReferenceRSs)) OF PUSCH-PathlossReferenceRS-Id · OPTIONAL Need N	Lists of reference signals for PUSCH path loss estimation to be released by the UE.
twoPUSCH-PC-AdjustmentStates ENUMERATED {twoStates} · OPTIONAL Need S	Number of PUSCH power control adjustment states maintained by the UE (i.e., fc(i)). If the field is present ( n2 ) the UE maintains two power control states (i.e., fc(i,0) and fc(i,1)). If the field is absent, it maintains one power control state (i.e., fc(i,0)) (see TS 38.213 [13], clause 7.1).
deltaMCS ENUMERATED {enabled} · OPTIONAL Need S	Indicates whether to apply delta MCS. When the field is absent, the UE applies Ks = 0 in delta_TFC formula for PUSCH (see TS 38.213 [13], clause 7.1).
sri-PUSCH-MappingToAddModList SEQUENCE (SIZE (1..maxNrofSRI-PUSCH-Mappings)) OF SRI-PUSCH-PowerControl · OPTIONAL Need N	A list of SRI-PUSCH-PowerControl elements among which one is selected (see TS 38.213 [13], clause 7.1). No elements in this list are configured if unifiedTCI-StateType is configured for the serving cell.
sri-PUSCH-MappingToReleaseList SEQUENCE (SIZE (1..maxNrofSRI-PUSCH-Mappings)) OF SRI-PUSCH-PowerControlId · OPTIONAL Need N
