Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The LTE V2X system's measurement mechanism is based on a single numerology, making it inadequate for the more flexible numerologies required by 5G NR V2X, leading to inefficiencies in payload control and transmission reliability.
Innovation Solution
A method involving X first-type measurements in a target time-frequency resource pool, followed by a target second-type measurement to determine Modulation Coding Scheme (MCS) and time-frequency resources, allowing for flexible numerology adaptation in 5G NR V2X.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single numerology measurement mechanism is used in LTE V2X, then the system structure is simple, but it cannot meet the flexible numerology requirements of 5G NR V2X
Solution Approach 1:
The measurement mechanism is segmented into multiple independent measurement types (first-type measurements for payload status and second-type measurements for channel quality). Each measurement type operates independently on different time-frequency resource pools with different numerologies, allowing the system to support multiple numerologies without requiring a completely new unified measurement framework.
Solution Approach 2:
The patent introduces a new dimension of measurement classification by numerology type. Instead of using a single measurement mechanism across all numerologies, the system now performs measurements in different measurement dimensions (first-type for payload, second-type for channel quality) on different time-frequency resource pools, enabling flexible numerology support while maintaining clear measurement boundaries.
2Measurement precision
If multiple measurement types are performed in different time-frequency resource pools, then measurement accuracy and flexibility improve, but the measurement process becomes more complex
Solution Approach 1:
The patent extracts the payload status measurement function into a separate first-type measurement that operates independently from channel quality measurements. By taking out the payload control measurement from the unified measurement framework, the system can optimize each measurement type for its specific purpose, improving accuracy while allowing independent optimization of each measurement process.
Solution Approach 2:
The measurement mechanism achieves multi-functionality by performing both first-type measurements (for payload status) and second-type measurements (for channel quality) within the same overall framework. This universal measurement system can adapt to different numerologies and service requirements, providing both specialized measurement accuracy and broad system applicability.
3Ease of manufacture
If LTE V2X measurement mechanism is applied to 5G NR V2X, then implementation is straightforward, but transmission reliability for diverse services deteriorates
Solution Approach 1:
The patent introduces dynamic adaptation to different numerologies while maintaining implementation simplicity. The measurement mechanism dynamically selects and performs appropriate measurement types (first-type or second-type) based on the numerology configuration and service requirements. This dynamic approach ensures transmission reliability for diverse services while keeping the implementation framework familiar and manageable.
