Dynamic Positioning Configuration for Wireless Terminal Measurement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face a large reporting delay in positioning measurements due to the periodic nature of downlink positioning reference signals (PRS) and the configuration of measurement gaps, which affects the accuracy and efficiency of terminal positioning.
Innovation Solution
A positioning measurement method that involves receiving indication information with positioning status IDs from a network device, determining the corresponding configuration, and performing positioning measurements and reporting, thereby reducing reporting delays by integrating positioning status configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If periodic downlink positioning reference signals are sent with measurement gaps configured, then positioning measurement can be performed, but reporting delay becomes large
Solution Approach 1:
The patent applies dynamics by enabling dynamic configuration of positioning status IDs and measurement gap parameters. The network can adjust the measurement gap duration and PRS transmission timing based on real-time positioning needs, transitioning from static periodic measurements to dynamic on-demand measurements, thereby reducing reporting delay while maintaining measurement accuracy.
Solution Approach 2:
The patent changes key parameters including the measurement gap duration, PRS transmission periodicity, and positioning status ID assignments. By modifying these parameters dynamically, the system can optimize between measurement accuracy and reporting speed, resolving the contradiction between precise positioning and fast reporting.
2Measurement precision
If measurement gap is configured for positioning measurement, then positioning can be measured, but positioning efficiency decreases
Solution Approach 1:
The system dynamically adjusts measurement gap configurations based on positioning urgency and availability. When high efficiency is needed, the network can reduce measurement gap duration or implement on-demand measurements without fixed periodic gaps, thereby improving positioning efficiency while maintaining required accuracy levels.
Solution Approach 2:
The patent segments positioning measurements into different status levels (e.g., first positioning status, second positioning status) with different measurement gap requirements. This allows the system to apply appropriate measurement granularity to different positioning scenarios, improving overall efficiency by avoiding unnecessary measurements in low-precision scenarios.
