SRS-Config field descriptions
tpc-Accumulation If the field is absent, UE applies TPC commands via accumulation. If disabled, UE applies the TPC command without accumulation (this applies to SRS when a separate closed loop is configured for SRS) (see clause 7.3 of TS 38.213).

SRS-Resource, SRS-PosResource field descriptions
cyclicShift-n2 Cyclic shift configuration (see clause 6.2.1 of TS 38.214).
cyclicShift-n4 Cyclic shift configuration (see clause 6.2.1 of TS 38.214).
cyclicShift-n8 Cyclic shift configuration (see clause 6.2.1 of TS 38.214).
enableStartRBHopping When this RRC parameter is configured, start RB location hopping is enabled for partial frequency sounding in different SRS frequency hopping periods for periodic/semi-persistent/aperiodic SRS as described in Clause 6.4.1.4 in TS 38.211.
freqHopping Includes parameters capturing SRS frequency hopping (see clause 6.2.1 of TS 38.214). For CLI SRS-RSRP measurement, the network always configures this field such that b-hop > b-SRS.
groupOrSequenceHopping Parameter(s) for configuring group or sequence hopping (see clause 6.4.1.4.2 of TS 38.211). For CLI SRS-RSRP measurement, the network always configures this parameter to 'neither'.
nrofSRS-Ports Number of ports. For CLI SRS-RSRP measurement, the network always configures this parameter to 'port1'.
periodicityAndOffset-p, periodicityAndOffset-p-Ext Periodicity and slot offset for this SRS resource. All values are in "number of slots". Value sl1 corresponds to a periodicity of 1 slot, value sl2 corresponds to a periodicity of 2 slots, and so on. For each periodicity the corresponding offset is given in number of slots. For periodicity sl1 the offset is 0 slots (see clause 6.2.1 of TS 38.214). For CLI SRS-RSRP measurement, sl1280 and sl2560 cannot be configured. For SRS-PosResource, values sl20480, sl40960 and sl81920 cannot be configured for SCS=15kHz, values sl40960 and sl81920 cannot be configured for SCS=30kHz, and value sl81920 cannot be configured for SCS=60kHz. When periodicityAndOffset-p-Ext is present, periodicityAndOffset-p shall be ignored by the UE.
periodicityAndOffset-sp, periodicityAndOffset-sp-Ext Periodicity and slot offset for this SRS resource. All values are in "number of slots". Value sl1 corresponds to a periodicity of 1 slot, value sl2 corresponds to a periodicity of 2 slots, and so on. For each periodicity the corresponding offset is given in number of slots. For periodicity sl1 the offset is 0 slots (see clause 6.2.1 of TS 38.214). For SRS-PosResource, values sl20480, sl40960 and sl81920 cannot be configured for SCS=15kHz, values sl40960 and sl81920 cannot be configured for SCS=30kHz, and value sl81920 cannot be configured for SCS=60kHz. When periodicityAndOffset-sp-Ext is present, periodicityAndOffset-sp shall be ignored by the UE.
ptrs-PortIndex The PTRS port index for this SRS resource for non-codebook based UL MIMO. This is only applicable when the corresponding PTRS-UplinkConfig is set to CP-OFDM. The ptrs-PortIndex configured here must be smaller than the maxNrofPorts configured in the PTRS-UplinkConfig (see clause 6.2.3.1 of TS 38.214). This parameter is not applicable to CLI SRS-RSRP measurement.
resourceMapping OFDM symbol location of the SRS resource within a slot including nrofSymbols (number of OFDM symbols), startPosition (value 0 refers to the last symbol, value 1 refers to the second last symbol, and so on) and repetitionFactor (see clause 6.2.1 of TS 38.214, and clause 6.4.1.4 of TS 38.211). The configured SRS resource does not exceed the slot boundary. If resourceMapping-r16 is signalled, UE shall ignore the resourceMapping (without suffix). If resourceMapping-r17 is signalled, resourceMapping-r16 is not signalled and the UE shall ignore the resourceMapping (without suffix) and only the values of nrofSymbols which are integer multiples of the configured repetitionFactor can be configured. The network can only signal repetitionFactor-v1730 if resourceMapping-r17 is signalled. When repetitionFactor-v1730 is signalled, the UE shall ignore repetitionFactor-r17. For CLI SRS-RSRP measurement, the network always configures nrofSymbols and repetitionFactor to 'n1'.
resourceType Periodicity and offset for semi-persistent and periodic SRS resource, or slot offset for aperiodic SRS resource for positioning (see clause 6.2.1 of TS 38.214). For CLI SRS-RSRP measurement, only 'periodic' is applicable for resourceType.
sequenceId Sequence ID used to initialize pseudo random group and sequence hopping (see clause 6.2.1 of TS 38.214).
spatialRelationInfo Configuration of the spatial relation between a reference RS and the target SRS. Reference RS can be SSB/CSI-RS/SRS (see clause 6.2.1 of TS 38.214). This parameter is not applicable to CLI SRS-RSRP measurement. This field is not configured if unifiedTCI-StateType is configured for the serving cell.
spatialRelationInfo-PDC Configuration of the spatial relation between a reference RS and the target SRS. Reference RS can be SSB/CSI-RS/SRS/DL-PRS-PDC (see clause 6.2.1 of TS 38.214). The field is present in case of resourceType=periodic and usagePDC-r17=true in the SRS-ResourceSet, otherwise the field is absent.
spatialRelationInfoPos Configuration of the spatial relation between a reference RS and the target SRS. Reference RS can be SSB/CSI-RS/SRS/DL-PRS (see clause 6.2.1 of TS 38.214). If the IE srs-ResourceId-Ext is present, the IE srs-ResourceId in spatialRelationInfoPos represents the index from 0 to 63. Otherwise the IE srs-ResourceId in spatialRelationInfoPos represents the index from 0 to 31.
srs-RequestDCI-0-2 Indicate the number of bits for "SRS request"in DCI format 0_2. When the field is absent, then the value of 0 bit for "SRS request" in DCI format 0_2 is applied. If the parameter srs-RequestDCI-0-2 is configured to value 1, 1 bit is used to indicate one of the first two rows of Table 7.3.1.1.2-24 in TS 38.212 for triggered aperiodic SRS resource set. If the value 2 is configured, 2 bits are used to indicate one of the rows of Table 7.3.1.1.2-24 in TS 38.212. When UE is configured with supplementaryUplink, an extra bit (the first bit of the SRS request field) is used for the non-SUL/SUL indication.
srs-RequestDCI-1-2 Indicate the number of bits for "SRS request" in DCI format 1_2. When the field is absent, then the value of 0 bit for "SRS request" in DCI format 1_2 is applied. When the UE is configured with supplementaryUplink, an extra bit (the first bit of the SRS request field) is used for the non-SUL/SUL indication (see clause 6.1.1.2 of TS 38.214).
srs-ResourceSetToAddModListDCI-0-2 List of SRS resource set to be added or modified for DCI format 0_2 (see clause 7.3.1 of TS 38.212).
srs-ResourceSetToReleaseListDCI-0-2 List of SRS resource set to be released for DCI format 0_2 (see clause 7.3.1 of TS 38.212).
srs-TCI-State Configuration of either a UL TCI state or a joint TCI state for the SRS resource. In case of UL TCI-State, refers to the TCI state defined in ul-TCI-StateList in the BWP-UplinkDedicated where the SRS-Config is configured. In case of joint TCI state, refers to a TCI state defined in dl-OrJointTCI-StateList in pdsch-Config of the BWP-DownlinkDedicated and serving cell indicated by cellAndBWP. This field is absent when the SRS resource is in an SRS-ResourceSet configured with followUnifiedTCI-StateSRS-r17 or when the field unifiedTCI-StateType is not configured to the serving cell which the SRS resource is located in.
startRBIndexAndFreqScalingFactor Configures the UE with the startRBIndex and freqScalingFactor for partial frequency sounding as described in clause 6.4.1.4 in TS 38.211. The startRBIndexForFScaling2 gives the startRBIndex when freqScalingFactor is 2 and the startRBIndexForFScaling4 gives the startRBIndex when FreqScalingFactor is 4
transmissionComb, transmissionComb-n8 Comb value (2 or 4 or 8) and comb offset (0..combValue-1) (see clause 6.2.1 of TS 38.214).

SRS-ResourceSet, SRS-PosResourceSet field descriptions
alpha alpha value for SRS power control (see clause 7.3 of TS 38.213). When the field is absent the UE applies the value 1.
aperiodicSRS-ResourceTriggerList An additional list of DCI "code points" upon which the UE shall transmit SRS according to this SRS resource set configuration (see clause 6 of TS 38.214). When the field is not included during a reconfiguration of SRS-ResourceSet of resourceType set to aperiodic, UE maintains this value based on the Need M; that is, this list is not considered as an extension of aperiodicSRS-ResourceTrigger for purpose of applying the general rule for extended list in clause 6.1.3.
aperiodicSRS-ResourceTrigger The DCI "code point" upon which the UE shall transmit SRS according to this SRS resource set configuration (see clause 6 of TS 38.214).
associatedCSI-RS ID of CSI-RS resource associated with this SRS resource set in non-codebook based operation (see clause 6.1.1.2 of TS 38.214).
availableSlotOffset Indicates the number of available slots from slot n+k to the slot where the aperiodic SRS resource set is transmitted, where slot n is the slot with the triggering DCI, and k is the legacy triggering offset (slotOffset, not based on availabel slot) as described in clause 6.2.1 of TS 38.214.
csi-RS ID of CSI-RS resource associated with this SRS resource set. (see clause 6.1.1.2 of TS 38.214).
dl-PRS This field indicates a PRS configuration.
followUnifiedTCI-StateSRS When set to enabled, for SRS resource Set, the UE applies the "indicated" UL only TCI or joint TCI as specified in clause 5.1.5 of TS 38.214. This parameter may be configured for aperiodic SRS for BM or SRS of any time-domain behavior for codebook, non-codebook, and antenna switching.
p0 P0 value for SRS power control. The value is in dBm. Only even values (step size 2) are allowed (see clause 7.3 of TS 38.213).
pathlossReferenceRS A reference signal (e.g. a CSI-RS config or a SS block) to be used for SRS path loss estimation (see clause 7.3 of TS 38.213).
pathlossReferenceRS-Pos A reference signal (e.g. a SS block or a DL-PRS config) to be used for SRS path loss estimation (see clause 7.3 of TS 38.213).
pathlossReferenceRSList Multiple candidate pathloss reference RS(s) for SRS power control, where one candidate RS can be mapped to SRS Resource Set via MAC CE (clause 6.1.3.27 in TS 38.321). The network can only configure this field if pathlossReferenceRS is not configured in the same SRS-ResourceSet.
resourceType Time domain behavior of SRS resource configuration, see clause 6.2.1 of TS 38.214. The network configures SRS resources in the same resource set with the same time domain behavior on periodic, aperiodic and semi-persistent SRS. The aperiodic SRS is not applicable for the UE in RRC_INACTIVE.
slotOffset An offset in number of slots between the triggering DCI and the actual transmission of this SRS-ResourceSet. If the field is absent the UE applies no offset (value 0).
srs-PowerControlAdjustmentStates Indicates whether hsrs,c(i) = fc(i,1) or hsrs,c(i) = fc(i,2) (if twoPUSCH-PC-AdjustmentStates are configured) or separate close loop is configured for SRS. This parameter is applicable only for Uls on which UE also transmits PUSCH. If absent or release, the UE applies the value sameAs-Fci1 (see clause 7.3 of TS 38.213).
srs-ResourceIdList, srs-PosResourceIdList The IDs of the SRS-Resources/SRS-PosResource used in this SRS-ResourceSet/SRS-PosResourceSet. If this SRS-ResourceSet is configured with usage set to codebook, the srs-ResourceIdList contains at most 2 entries. If this SRS-ResourceSet is configured with usage set to nonCodebook, the srs-ResourceIdList contains at most 4 entries.
srs-ResourceSetId, srs-PosResourceSetId The ID of this resource set. It is unique in the context of the BWP in which the parent SRS-Config is defined.

ssb-IndexServing Indicates SSB index belonging to a serving cell.
ssb-Ncell This field indicates a SSB configuration from neighboring cell.

SSB-InfoNCell field descriptions
physicalCellId This field specifies the physical cell ID of the neighbour cell for which SSB configuration is provided.
ssb-IndexNcell This field specifies the index of the SSB for a neighbour cell. See TS 38.213. If this field is absent, the UE determines the ssb-IndexNcell of the physicalCellId based on its SSB measurement from the cell.
ssb-Configuration This field specifies the full configuration of the SSB. If this field is absent, the UE obtains the configuration for the SSB from nr-SSB-Config received as part of DL-PRS assistance data in LPP, see TS 37.355, by looking up the corresponding SSB configuration using the field physicalCellId.

DL-PRS-Info field descriptions
