AI Technical Summary

Technical Problem

In sidelink positioning, neighboring user equipments select the same comb size and RE offset parameters, which leads to a degradation in positioning performance. Simply avoiding the SL-PRS resources of other UEs will cause resource waste and delay.

Method used

SL PRS resource parameters are coordinated between user equipments to avoid conflicts by indicating SL PRS resource parameters, selecting non-overlapping comb sizes and RE offsets, and requesting muting of SL PRS transmissions.

Benefits of technology

The performance of sidelink positioning is improved, resource waste and delay are reduced, and more efficient resource utilization is achieved.
