AI Technical Summary

Technical Problem

Current wireless communication systems face challenges in accurately determining the position of user equipment (UE) using sidelink positioning reference signals (SL-PRS), particularly in scenarios where feedback mechanisms are limited or absent.

Method used

The proposed method involves a feedback mode mechanism for sidelink positioning reference signals, where a user equipment (UE) receives a sidelink positioning reference signal resource configuration and a feedback mode indication. Based on this feedback mode and specific measurement criteria, the UE determines whether to transmit feedback associated with SL-PRS measurements.

Benefits of technology

This approach enhances the accuracy and reduces the latency of SL-based position estimation by allowing for controlled feedback mechanisms, thereby improving overall positioning performance in wireless communication systems.
