UE Positioning Measurement for Autonomous Timing Compensation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In satellite communication systems, the lack of measurement trigger information can lead to communication failures due to outdated timing compensation, resulting in service interruptions and increased power consumption.
Innovation Solution
User equipment (UE) is configured to perform active positioning measurements based on a positioning measurement configuration, allowing it to determine timing compensation without relying on measurement trigger information, thereby updating position information and ensuring valid timing compensation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the UE waits for measurement trigger information from the network device to perform positioning measurements, then the system follows a standardized measurement procedure, but the positioning measurement flexibility deteriorates and service interruptions occur when trigger information is not received
Solution Approach 1:
The UE is configured with positioning measurement configuration information that enables it to autonomously perform positioning measurements and determine timing compensation without requiring external trigger information. The UE serves itself by independently initiating measurements based on pre-configured parameters, thereby eliminating service interruptions caused by missing trigger information while maintaining measurement flexibility
2Reliability
If the UE performs positioning measurements only when triggered by the network device, then the system maintains centralized control, but the timing compensation may become outdated leading to service interruptions
Solution Approach 1:
The network device pre-configures the UE with positioning measurement configuration information including measurement parameters and timing compensation settings before the UE needs to perform measurements. This preliminary configuration enables the UE to execute measurements autonomously when needed, ensuring timing compensation remains valid without requiring complex real-time control mechanisms
3Productivity
If the UE continuously monitors for measurement trigger information, then the UE can respond to network commands, but power consumption increases due to unnecessary monitoring when measurements are not needed
Solution Approach 1:
Instead of continuously monitoring for trigger information, the UE is configured to perform positioning measurements periodically based on pre-configured measurement parameters. The UE activates measurement functions only when configured to do so, maintaining measurement response efficiency while significantly reducing power consumption by avoiding continuous monitoring states
