SL-RemoteUE-ConfigU2U field descriptions
sl-RSRP-ThreshU2U Indicates the threshold of SL-RSRP for a U2U Remote UE to perform Relay UE selection/ reselection. The U2U remote UE applies the value of this field to evaluate AS layer conditions on direct PC5 link with the peer U2U Remote UE to trigger relay selection, and evaluate AS layer conditions on U2U relay link with U2U Relay UE to trigger relay reselection.
sl-FilterCoefficientU2U Specifies L3 filter coefficient for SL-RSRP measurement results from L1 filter.
sd-RSRP-ThreshU2U Indicates the threshold of SD-RSRP for a U2U Remote UE to perform discovery and Relay UE selection/ reselection. For discovery, the U2U Remote UE applies the value of this field to evaluate AS layer conditions to decide whether to respond the discovery message when performing the U2U Relay Discovery with Model B as specified in TS 23.304. For relay selection and reselection, the U2U remote UE applies the value of this field to evaluate AS layer conditions on direct PC5 link to trigger relay selection, and evaluate AS layer conditions on U2U relay link to trigger relay reselection. The target U2U remote UE applies the value of this field to evaluate AS layer conditions trigger relay selection when performing U2U relay communication with integrated Discovery as specified in TS 23.304.
sd-FilterCoefficientU2U Specifies L3 filter coefficient for SD-RSRP measurement results from L1 filter.

SL-RSRP-ThreshU2U	This field is mandatory present if sl-RSRP-ThreshU2U is included. Otherwise, the field is absent, Need R.
SD-RSRP-ThreshU2U	This field is mandatory present if sd-RSRP-ThreshU2U is included. Otherwise, the field is absent, Need R.

sl-CPE-StartingPositionPSFCH Indicates CPE starting position within the GP symbol before PSFCH transmission. The value is an index of the set of all candidate CPE starting positions specified in Table 5.3.1-3 of TS 38.211 for Ci=1 and the corresponding SCS of the SL BWP.
sl-FilterCoefficient This field indicates the filtering coefficient for long-term measurement and reference signal power derivation used for sidelink open-loop power control.
sl-InterUE-CoordinationConfig Indicates the configured sidelink inter-UE coordination parameters.
sl-IUC-RB-SetList The n-th value in the list indicates the set of PRBs that are actually used for inter-UE coordination information transmission and reception in Scheme 2. It shall be (pre-)configured such that N candidate PSFCH occasion(s) are associated with N different PRB sets. PRBs within intra-cell guard band are not used for PSFCH transmission. The length of this list is aligned with sl-NumPSFCH-Occasions. For each PSFCH occasion, the set of PRBs are indicated in the same format as in sl-PSFCH-RB-Set.
sl-NumDedicatedPRBs-ForPSFCH Indicates the value of K3 when each PSFCH transmission occupies "1 common interlace and K3 dedicated PRB(s)" (as indicated by sl-TransmissionStructureForPSFCH). Value prb1 corresponds to K3=1, value prb2 corresponds to K3=2, and so on. UE expects the same (pre-)configured value of sl-NumDedicatedPRBs-ForPSFCH across all resource pools.
sl-NumInterlacePerSubchannel Indicates the number of (K) interlaces per sub-channel within a resource pool. Value sc1 corresponds to 1 interlace per sub-channel, and value sc2 corresponds to 2 interlaces per sub-channel. The applicable values are related to the subcarrier spacing as below: For SCS = 15 kHz: K=1 or 2 For SCS = 30 kHz: K=1
sl-NumPSFCH-Occasions Indicates one PSCCH/PSSCH transmission has N associated candidate PSFCH occasion(s). Value o1 corresponds to N=1, value o2 corresponds to N=2, and so on. If the field is not configured, the UE shall use value o1.
sl-NumReferencePRBs-OfInterlace Indicate reference number of PRBs of one interlace within 1 RB set. Value prb10 corresponds to 10 PRBs, and value prb11 corresponds to 11 PRBs.
sl-NumRefSymbolLength Indicates a reference number of symbols for TBS determination.
sl-NumSubchannel Indicates the number of subchannels in the corresponding resource pool, which consists of contiguous PRBs only.
sl-PBPS-CPS-Config Indicates the allowed resource allocation schemes of full sensing only, partial sensing only, random resource selection only, or any combination(s), and the related configuration for power saving resource allocation schemes. This field is absent for sl-TxPoolExceptional.
sl-PreemptionEnable Indicates whether pre-emption is disabled or enabled in a resource pool. If the field is present and the value is pl1, pl2, and so on (but not enabled), it means that pre-emption is enabled and a priority level p_preemption is configured. If the field is present and the value is enabled, the pre-emption is enabled (but p_preemption is not configured) and pre-emption is applicable to all levels.
sl-PriorityThreshold-UL-URLLC Indicates the threshold used to determine whether NR sidelink transmission is prioritized over uplink transmission of priority index 1 as specified in clause 16.2.4.3 of TS 38.213, or whether PUCCH transmission carrying SL HARQ is prioritized over PUCCH transmission carrying UCI of priority index 1 if they overlap in time as specified in clause 9.2.5.0 of TS 38.213.
sl-PriorityThreshold Indicates the threshold used to determine whether NR sidelink transmission is prioritized over uplink transmission of priority index 0 as specified in clause 16.2.4.3 of TS 38.213, or whether PUCCH transmission carrying SL HARQ is prioritized over PUCCH transmission carrying UCI of priority index 0 if they overlap in time as specified in clause 9.2.5.0 of TS 38.213.

sl-PSFCH-PowerOffset Indicates the power offset between Tx power on one common PRB (P_common) and Tx power on one dedicated PRB (P_dedicated) when sl-TransmissionStructureForPSFCH is (pre-)configured as commonInterlace, i.e., P_common = P_dedicated - offset. UE expects the same (pre-)configured value of sl-PSFCH-PowerOffset across all resource pools. The unit is dB.

– SL-Thres-RSRP-List p. 1395

The IE SL-Thres-RSRP-List indicates a threshold used for sensing based UE autonomous resource selection (see TS 38.215). A resource is excluded if it is indicated or reserved by a decoded SCI and PSSCH/PSCCH RSRP in the associated data resource is above the threshold defined by IE SL-Thres-RSRP-List. A NR sidelink resource is excluded if the corresponding PSFCH transmission occasions overlap with resources indicated or reserved by the decoded EUTRA SCI in time domain and EUTRA PSSCH RSRP in the associated data resource is above the threshold defined by IE sl-NRPSFCH-EUTRA-ThresRSRP-List. A NR sidelink resource is excluded if it is indicated or reserved by the decoded EUTRA SCI and EUTRA PSSCH RSRP in the associated data resource is above the threshold defined by IE sl-NRPSSCH-EUTRA-ThresRSRP-List. Value 0 corresponds to minus infinity dBm, value 1 corresponds to -128dBm, value 2 corresponds to -126dBm, value n corresponds to (-128 + (n-1)*2) dBm and so on, value 66 corresponds to infinity dBm.
