| Field | Description |
|---|---|
| sl-RSRP-ThreshU2U-r18 SL-RSRP-Range-r16 · OPTIONAL Need R | 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-HystMinU2U-r18 Hysteresis · OPTIONAL Cond SL-RSRP-ThreshU2U | |
| sd-RSRP-ThreshU2U-r18 SL-RSRP-Range-r16 · OPTIONAL Need R | 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 [65]. 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 [65]. |
| sd-FilterCoefficientU2U-r18 FilterCoefficient · OPTIONAL Need R | Specifies L3 filter coefficient for SD-RSRP measurement results from L1 filter, and for SL-RSRP measurement. |
| sd-HystMinU2U-r18 Hysteresis · OPTIONAL Cond SD-RSRP-ThreshU2U |
