Positioning Center Coverage Adaptation for UE Measurement Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In prior-art positioning methods, user equipment (UE) with poor coverage is required to perform extensive measurements, leading to increased power consumption and signaling overheads, despite the positioning measurement configuration being unsuitable for the UE's coverage conditions.
Innovation Solution
A method where a positioning center obtains coverage indication information to determine a flexible measurement configuration for the UE, reducing the number of cells to be measured and configuring appropriate response times, allowing the UE to complete positioning measurements efficiently in poor coverage without triggering additional measurements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the positioning center requires UE to perform extensive measurements based on positioning measurement configuration, then positioning measurement coverage is improved, but UE power consumption and signaling overheads increase
Solution Approach 1:
The patent applies local quality by differentiating measurement configuration based on UE coverage conditions. The positioning center identifies UE in poor coverage through coverage indication information and applies a simplified measurement configuration specifically to these UEs, while maintaining standard configuration for UEs with good coverage. This localized adaptation reduces power consumption for poor coverage UEs without compromising their positioning capability.
Solution Approach 2:
The patent implements dynamic measurement configuration where the positioning center adjusts the quantity of to-be-measured cells based on real-time coverage conditions. The system dynamically switches between extensive measurement configuration (for good coverage) and reduced measurement configuration (for poor coverage), allowing the measurement requirements to adapt to changing UE conditions rather than applying a static configuration to all UEs.
2Measurement precision
If the positioning center requires UE to perform extensive measurements, then positioning measurement accuracy is improved, but signaling overheads increase
Solution Approach 1:
The patent applies local quality by tailoring measurement configuration to specific UE coverage conditions. For UE in poor coverage, the system reduces the quantity of to-be-measured cells and adjusts response time parameters, thereby reducing signaling overheads while maintaining sufficient positioning accuracy for these challenging conditions. This localized configuration avoids the waste of requiring extensive measurements from UEs that already have good coverage.
Solution Approach 2:
The patent changes key parameters of the measurement configuration based on coverage conditions. The positioning center modifies the quantity of to-be-measured cells, response time requirements, and measurement frequency according to the UE's coverage indication information. These parameter adjustments reduce signaling overheads for poor coverage UEs while maintaining positioning accuracy within acceptable bounds.
3Measurement precision
If the positioning center configures standard positioning measurement configuration for all UE, then positioning accuracy is maintained, but UE in poor coverage cannot complete measurements efficiently
Solution Approach 1:
The patent implements dynamic adaptation of measurement configuration based on real-time coverage assessment. The positioning center receives coverage indication information from UE or base stations and dynamically adjusts measurement parameters accordingly. For poor coverage UEs, the system extends response times and reduces measurement quantities, enabling these UEs to complete measurements successfully without triggering additional measurements, thereby improving productivity for vulnerable UEs while maintaining overall positioning accuracy.
Solution Approach 2:
The patent applies preliminary action by having the positioning center proactively identify UE in poor coverage through coverage indication information before positioning measurements begin. Based on this preliminary assessment, the positioning center pre-configures appropriate measurement parameters including extended response times and reduced cell quantities, allowing poor coverage UEs to complete measurements efficiently without needing to trigger additional measurement rounds.

AI summary
The present disclosure relates to information transmission methods. One example method includes obtaining, by a positioning center, coverage indication information, where the coverage indication information is used to indicate a coverage enhancement level of user equipment UE, indicate that UE is at a first coverage enhancement level, or to indicate that UE requests to reduce a quantity of to-be-measured cells, and sending, by the positioning center, positioning measurement configuration information to the UE, where the positioning measurement configuration information is determined by the positioning center based on the coverage indication information, and the positioning measurement configuration information is used to perform positioning measurement configuration on the UE.
