Motion State Configuration for Wireless Positioning Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional motion state reporting in wireless communication systems, such as LTE, lacks sufficient positioning accuracy in scenarios like factory automation where movement is controlled and predictable, leading to potential collisions due to uncertainty in speed and path definitions.
Innovation Solution
Enhanced reporting of positioning-related states by identifying and reporting a motion state configuration associated with a mobile device's movement, which includes information on possible positions, speed, and timing uncertainties, allowing for improved position determination using a positioning device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional motion state reporting is used, then device complexity is reduced, but positioning accuracy deteriorates
Solution Approach 1:
The patent changes the parameters of motion state reporting by introducing motion state configurations that include not only conventional motion states but also additional parameters such as possible positions, speed, and timing uncertainties. This allows the system to provide more precise positioning information while maintaining the existing reporting framework, thereby improving positioning accuracy without significantly increasing device complexity.
Solution Approach 2:
The patent segments the motion state information into distinct components: motion state indicators, possible positions, speed information, and timing uncertainties. By dividing the complex positioning data into manageable segments, the system can report positioning-related states more effectively, improving accuracy while keeping the reporting structure organized and not overly complex.
2Reliability
If conventional motion state reporting is used, then ease of operation is maintained, but reliability deteriorates
Solution Approach 1:
The patent implements feedback mechanisms where the mobile device reports motion state configurations that include uncertainty information about position, speed, and timing. This feedback allows the positioning device to adjust its calculations and provide more reliable position determination, while the system maintains ease of operation by automatically processing the enhanced information without requiring manual intervention.
Solution Approach 2:
The patent performs preliminary actions by pre-defining motion state configurations and their associated parameters before actual positioning operations. This allows the system to prepare and structure the positioning data in advance, improving reliability through more comprehensive data collection while maintaining ease of operation through automated processing of pre-structured information.
3Measurement precision
If enhanced motion state reporting is implemented, then positioning accuracy is improved, but use of energy increases
Solution Approach 1:
The patent applies partial action by reporting only the necessary additional parameters (possible positions, speed, timing uncertainties) when needed for enhanced positioning accuracy, rather than continuously reporting all possible motion state data. This selective reporting approach improves positioning accuracy when required while minimizing unnecessary energy consumption during normal operations.
Solution Approach 2:
The patent implements dynamic reporting where the mobile device adjusts the level of detail in motion state reporting based on the positioning requirements and available resources. The system can dynamically switch between conventional and enhanced reporting modes, allowing it to improve positioning accuracy when needed while reducing energy consumption during operations where maximum precision is not critical.
