Fields (9)

FieldDescription
deltaF-PUCCH-f0
INTEGER (-16..15) · OPTIONAL Need R
deltaF for PUCCH format 0 with 1dB step size (see TS 38.213 [13], clause 7.2).
deltaF-PUCCH-f1
INTEGER (-16..15) · OPTIONAL Need R
deltaF for PUCCH format 1 with 1dB step size (see TS 38.213 [13], clause 7.2).
deltaF-PUCCH-f2
INTEGER (-16..15) · OPTIONAL Need R
deltaF for PUCCH format 2 with 1dB step size (see TS 38.213 [13], clause 7.2).
deltaF-PUCCH-f3
INTEGER (-16..15) · OPTIONAL Need R
deltaF for PUCCH format 3 with 1dB step size (see TS 38.213 [13], clause 7.2).
deltaF-PUCCH-f4
INTEGER (-16..15) · OPTIONAL Need R
deltaF for PUCCH format 4 with 1dB step size (see TS 38.213 [13], clause 7.2).
p0-Set
SEQUENCE (SIZE (1..maxNrofPUCCH-P0-PerSet)) OF P0-PUCCH · OPTIONAL Need M
A set with dedicated P0 values for PUCCH, i.e., {P01, P02,... } (see TS 38.213 [13], clause 7.2). This field is not configured if unifiedTCI-StateType is configured for the serving cell.
pathlossReferenceRSs
SEQUENCE (SIZE (1..maxNrofPUCCH-PathlossReferenceRSs)) OF PUCCH-PathlossReferenceRS · OPTIONAL Need M
A set of Reference Signals (e.g. a CSI-RS config or a SS block) to be used for PUCCH pathloss estimation. Up to maxNrofPUCCH-PathlossReference-RSs may be configured. If the field is not configured, the UE uses the SSB as reference signal (see TS 38.213 [13], clause 7.2). The set includes Reference Signals indicated in pathlossReferenceRSs (without suffix) and in pathlossReferenceRSs-v1610. The UE maintains pathlossReferenceRSs and pathlossReferenceRSs-v1610 separately: Receiving pathlossReferenceRSs-v1610 set to release releases only the entries that were configured by pathlossReferenceRSs-v1610 , and receiving pathlossReferenceRSs-v1610 set to setup replaces only the entries that were configured by pathlossReferenceRSs-v1610 with the newly signalled entries. Neither the field pathlossReferenceRSs (without suffix) nor pathlossReferenceRSs-v1610 are configured if unifiedTCI-StateType is configured for the serving cell.
twoPUCCH-PC-AdjustmentStates
ENUMERATED {twoStates} · OPTIONAL Need S
Number of PUCCH power control adjustment states maintained by the UE (i.e., g(i)). If the field is present (n2) the UE maintains two power control states (i.e., g(i,0) and g(i,1)). If the field is absent, it maintains one power control state (i.e., g(i,0)) (see TS 38.213 [13], clause 7.2).
pathlossReferenceRSs-v1610
SetupRelease { PathlossReferenceRSs-v1610 } · OPTIONAL Need M
since v16.1.0
A set of Reference Signals (e.g. a CSI-RS config or a SS block) to be used for PUCCH pathloss estimation. Up to maxNrofPUCCH-PathlossReference-RSs may be configured. If the field is not configured, the UE uses the SSB as reference signal (see TS 38.213 [13], clause 7.2). The set includes Reference Signals indicated in pathlossReferenceRSs (without suffix) and in pathlossReferenceRSs-v1610. The UE maintains pathlossReferenceRSs and pathlossReferenceRSs-v1610 separately: Receiving pathlossReferenceRSs-v1610 set to release releases only the entries that were configured by pathlossReferenceRSs-v1610 , and receiving pathlossReferenceRSs-v1610 set to setup replaces only the entries that were configured by pathlossReferenceRSs-v1610 with the newly signalled entries. Neither the field pathlossReferenceRSs (without suffix) nor pathlossReferenceRSs-v1610 are configured if unifiedTCI-StateType is configured for the serving cell.
