Periodic Positioning Report Enhancement for 5G IoT
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems, particularly in 5G NR, face challenges in efficiently managing periodic positioning reports, which can lead to latency and accuracy issues in closed-loop systems and latency-sensitive applications like IoT.
Innovation Solution
The proposed solution involves enhancing periodic positioning reports by incorporating indications of measurement instance related information or expiration time related information. This allows for more precise timing and interval management of PRS measurements and location information reports, thereby improving latency and accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If periodic positioning reports are transmitted without enhanced timing management, then the system complexity remains low, but latency and accuracy deteriorate
Solution Approach 1:
The network entity pre-configures the UE with reporting configurations including time instance indications and expiration time information before positioning reports are generated. This preliminary setup establishes timing constraints and measurement opportunities in advance, enabling the UE to proactively manage report generation and transmission timing, thereby reducing latency without adding complex real-time decision-making mechanisms.
Solution Approach 2:
The positioning report system implements dynamic timing management where the network entity can update reporting configurations, measurement opportunities, and expiration times based on changing system conditions. The UE adapts its report generation timing dynamically according to configured parameters and actual measurement availability, allowing the system to optimize latency performance under varying operational conditions without requiring overly complex static structures.
2Measurement precision
If periodic positioning reports are transmitted without enhanced timing management, then the configuration remains simple, but measurement accuracy deteriorates
Solution Approach 1:
The network entity provides the UE with preliminary configuration information including measurement opportunity indications, time instance parameters, and expiration time settings before measurements are performed. This advance configuration enables the UE to precisely time its measurements and report generation, improving measurement accuracy by ensuring measurements are taken at optimal moments without requiring complex real-time analysis or adaptive algorithms.
3Measurement precision
If periodic positioning reports are transmitted frequently, then location accuracy improves, but network resource consumption increases
Solution Approach 1:
The system implements periodic positioning report transmission with configurable intervals and timing parameters. The network entity configures the UE with periodic reporting patterns that balance location accuracy requirements against network resource consumption. By optimizing the periodicity and timing of reports based on application needs and network conditions, the system achieves necessary location accuracy while minimizing unnecessary transmissions and resource usage.
Solution Approach 2:
The network entity dynamically adjusts reporting parameters including time instances, expiration times, and measurement opportunities based on network conditions, UE capability, and application requirements. This parameter optimization allows the system to transmit reports frequently enough to maintain required location accuracy while reducing overall transmission frequency and resource consumption by eliminating redundant or premature reports.
