Connected Intelligent Edge Positioning With DL RS Coordination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in achieving accurate and efficient positioning, particularly in multi-operator and multi-TRP environments, due to network synchronization issues and the complexity of managing downlink reference signals across different network operators and transmission-reception points.
Innovation Solution
The implementation of a connected intelligent edge (CIE) server that manages and coordinates downlink reference signals (DL RS) across multiple network operators and TRPs, including configuration and measurement coordination, to enhance positioning accuracy and synchronization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If downlink reference signals are transmitted across multiple network operators and TRPs, then positioning coverage and accuracy are improved, but network synchronization complexity increases
Solution Approach 1:
The CIE server acts as an intermediary that coordinates DL RS transmission across multiple network operators and TRPs. It receives positioning requests from UEs, determines optimal TRP configurations, and manages the synchronization of reference signals without requiring direct coordination between multiple operators' network elements, thereby reducing synchronization complexity while maintaining positioning accuracy
Solution Approach 2:
The CIE server performs multiple functions including positioning request handling, TRP identification, DL RS configuration determination, and synchronization coordination. This multi-functional approach consolidates what would otherwise require multiple specialized systems, reducing overall network complexity while enabling multi-operator positioning
2Measurement precision
If the CIE server coordinates DL RS across multiple network operators and TRPs, then positioning accuracy is improved, but system complexity increases
Solution Approach 1:
The CIE server serves as a centralized intermediary that simplifies the coordination of DL RS across multiple operators and TRPs. By consolidating coordination functions in a single entity rather than requiring distributed coordination between multiple network elements, the system achieves improved positioning accuracy without proportionally increasing overall system complexity
Solution Approach 2:
The patent combines multiple positioning-related functions (request handling, TRP selection, RS configuration, synchronization) into a single CIE server system. This merging of functions that would otherwise be distributed across multiple network elements reduces system complexity while maintaining the capability to coordinate across multiple operators and TRPs

AI summary
Disclosed are techniques for positioning. In an aspect, a connected intelligent edge (CIE) server receives, from a first user equipment (UE), first configuration information for one or more first downlink reference signals (DL RS) transmitted on a serving cell of the first UE, receives, from the first UE, identifiers of one or more neighbor cells of the first UE, and transmits, to the first UE, a response including second configuration information for one or more second DL RS transmitted on the one or more neighbor cells of the first UE, the one or more second DL RS being a same type of DL RS as the one or more first DL RS.
