Solution Overview

Problem

Current wireless communication systems face challenges in efficiently managing sidelink positioning procedures, particularly in congested networks where excessive network resources are utilized for query-based procedures and anchor configuration.

Innovation Solution

A method where a base station provides a threshold value for a sidelink positioning procedure, and mobile stations autonomously determine their suitability to anchor the procedure based on this threshold, thereby dynamically controlling which UEs can perform sidelink positioning.
