Question: What information may be included by the UE when reporting one or more of the SL RSTD, SL Rx-Tx time difference, SL RTOA, SL AoA, SL PRS-RSRP, and SL PRS-RSRPP measurements for sidelink positioning reference signals (SL PRS)?
Option 1: Only the measurement values themselves
Option 2: An ARP ID associated with the reported measurements, and optionally, SL PRS resource ID(s), LoS/NLoS indicator(s), synchronization information, and/or quality metrics
Option 3: The UE's location information and the location information of other UEs in the network
Option 4: Details of the higher layer parameters used for configuration
Explanation: This option is correct because, according to the specifications, when reporting measurements for SL PRS, the UE may include additional information such as an ARP ID (Associated Radio Paging ID) associated with the measurements, and optionally, SL PRS resource ID(s) for identification, LoS/NLoS (Line of Sight/Non-Line of Sight) indicator(s) for environment context, synchronization information for timing accuracy, and/or quality metrics (like time quality or angle quality) to indicate the reliability of the measurements. This comprehensive reporting enhances the utility of the measurements for positioning and network optimization purposes.
