Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems lack efficient enhancements for UE processing timelines in RAT-dependent positioning procedures, leading to high latency and inefficiencies in measurement and reporting of positioning-related reference signals, particularly in stringent latency and accuracy requirements of Release 17 3GPP specifications for Industrial IoT and indoor factory settings.
Innovation Solution
The solution introduces dynamic Layer-1/2 signaling and uplink configured grants for positioning, along with priority indications and criteria-based dropping of measurement reports, to optimize UE processing timelines and reduce latency in positioning-related reference signal measurements and reports.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If traditional positioning measurement procedures are used, then positioning measurements can be performed, but latency is high and processing efficiency is low
Solution Approach 1:
The patent implements dynamic processing timelines that adapt to UE capabilities and resource availability. The network can configure different processing timeline lengths (e.g., first timeline longer than second timeline) based on UE processing capability indicators, allowing the system to optimize between latency and processing load dynamically rather than using fixed timelines
Solution Approach 2:
The patent changes key parameters including processing timeline length, measurement quantity types, and reporting configurations based on UE capabilities. The network configures different time lengths for processing different quantities of measurements, and adjusts these parameters dynamically to reduce latency while matching UE processing capabilities
2Measurement precision
If more positioning measurements are processed, then positioning accuracy improves, but processing time and latency increase
Solution Approach 1:
The patent configures different processing timeline lengths based on the quantity and type of measurements to be processed. For example, longer timelines are allocated for processing larger quantities of measurements requiring high accuracy, while shorter timelines are used for smaller measurement sets, optimizing the balance between accuracy and processing time
Solution Approach 2:
The patent implements criteria-based dropping of measurement reports when resource constraints or latency requirements prevent processing all measurements. The network can configure criteria such as minimum measurement quantities, priority levels, or time thresholds, allowing partial processing of measurements to meet latency requirements while maintaining acceptable positioning accuracy
3Productivity
If UE processing capability is increased, then more measurements can be processed faster, but device complexity and power consumption increase
Solution Approach 1:
The patent enables UEs to self-report their processing capabilities to the network, which then configures appropriate processing timelines and measurement quantities accordingly. This allows the system to optimize for each UE's actual capabilities without requiring all UEs to have high-end processing power, reducing device complexity requirements while maintaining overall system productivity
Solution Approach 2:
The patent adjusts processing timeline parameters and measurement configuration parameters based on reported UE capabilities. The network configures longer timelines for UEs with lower processing capabilities and shorter timelines for UEs with higher capabilities, optimizing the balance between processing productivity and device complexity across the network
4Speed
If measurement reporting is performed frequently, then positioning updates are timely, but network resource consumption and signaling overhead increase
Solution Approach 1:
The patent implements periodic measurement reporting with configurable time intervals between reports. Instead of continuous reporting, the system uses periodic updates at optimized intervals that balance timely positioning information with reduced signaling overhead and network resource consumption
Solution Approach 2:
The patent configures reporting parameters including time intervals, trigger conditions, and measurement quantity selections based on network resource availability and positioning requirements. The network can adjust these parameters dynamically to optimize the balance between update speed and resource consumption
