PRS Parameter Preconfiguration for Low-Latency Terminal Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing positioning technologies in the Industrial Internet of Things (IIoT) fail to meet the requirement of reducing end-to-end latency for terminal positioning, as PRS parameters are configured during the positioning process, which is insufficient for low-latency applications.
Innovation Solution
Pre-configure PRS configuration parameters for terminals, allowing them to measure positioning signals without additional configuration information during the positioning process, thereby reducing latency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If PRS parameters are configured during the positioning process, then positioning accuracy is ensured, but positioning latency increases
Solution Approach 1:
The patent pre-configures PRS parameter sets before the positioning process begins. The terminal receives and stores multiple PRS configuration parameter sets in advance, so that when positioning is needed, the terminal can directly use the pre-configured parameters without waiting for real-time configuration, thereby reducing positioning latency while ensuring positioning accuracy through the use of pre-optimized parameter sets
2Measurement precision
If PRS configuration is provided in real-time during positioning, then positioning precision is maintained, but system complexity increases
Solution Approach 1:
The patent reduces system complexity by pre-configuring PRS parameters before positioning operations. Instead of requiring real-time configuration communication between network and terminal during positioning, the terminal receives and stores multiple PRS configuration parameter sets in advance, eliminating the need for complex real-time configuration management while maintaining positioning precision through the use of pre-optimized parameter sets

AI summary
A parameter configuration method is performed by a terminal, and includes: determining a preconfigured positioning reference signal (PRS) configuration parameter set, wherein the PRS configuration parameter set includes at least one set of PRS configuration parameters; and determining a set of PRS configuration parameters for receiving a PRS based on the PRS configuration parameter set.
