Solution Overview

Problem

Existing communication networks face challenges in accurately evaluating modulation schemes due to limited information about less frequently used schemes, leading to incorrect selections and imbalanced communication metric data across multiple modulation schemes.

Innovation Solution

The technique attributes communication metric data from frequently used modulation schemes to less frequently used schemes by updating metrics based on successful or unsuccessful transmissions, harmonizing data across all schemes and improving evaluation accuracy.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If modulation scheme selection is based on available metrics only, then the selection process is simple, but the evaluation accuracy deteriorates when information is limited

Engineering Contradiction:
Improvemodulation scheme evaluation accuracyVSAvoidmetric collection and processing complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent merges metric data from multiple modulation schemes by attributing communication metrics from a first modulation scheme to a second modulation scheme. This combines limited available data with inferred data to create a more complete evaluation basis, improving accuracy without requiring separate extensive measurements for each scheme.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The system performs preliminary metric collection and attribution before modulation scheme selection. By pre-processing and attributing metrics from frequently used schemes to less frequently used ones, the system ensures accurate evaluation data is ready before the actual selection decision, avoiding the need for complex real-time analysis.

Inventive Principle:
Principle #10Preliminary action

2Quantity of substance

If communication metrics are collected only for actually used modulation schemes, then data collection is efficient, but the quantity and balance of data deteriorates for less frequently used schemes

Engineering Contradiction:
Improvequantity of communication metric dataVSAvoiddata collection efficiency
Core Design Contradiction:
Quantity of substanceVSProductivity

Solution Approach 1:

The patent creates copies of communication metric data by attributing performance metrics from the first modulation scheme to the second modulation scheme. This copying mechanism generates additional data for less frequently used schemes without requiring separate physical measurements, thus increasing data quantity while maintaining collection efficiency.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The system makes communication metrics universal by allowing metrics collected from one modulation scheme to serve evaluation purposes for multiple modulation schemes. This multi-functional use of data ensures that limited measurements contribute to the evaluation of several schemes, balancing data distribution across all schemes.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Reliability

If modulation scheme with more metrics is selected, then the selection confidence is higher, but the reliability deteriorates when the scheme actually performs worse

Engineering Contradiction:
Improvecommunication reliabilityVSAvoidinformation about actual performance
Core Design Contradiction:
ReliabilityVSLoss of information

Solution Approach 1:

The system uses feedback from actual communication performance to attribute metrics to multiple modulation schemes. By incorporating real performance outcomes and propagating this feedback across related schemes, the system ensures that selected schemes are evaluated based on actual performance data, improving reliability over mere metric quantity.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system performs preliminary attribution of performance metrics to establish accurate evaluation data before selection. This pre-processing ensures that when a scheme is selected, it has been properly evaluated with reliable attributed data, preventing selection based on incomplete or misleading information.

Inventive Principle:
Principle #10Preliminary action

AI summary

Techniques directed to attributing information regarding communications with a modulation scheme to a different modulation scheme are described. In one example, a successful communication for a higher data rate modulation scheme may be attributed to a lower data rate modulation scheme. Such attribution may infer that the lower data rate modulation scheme would have also been successful if it had been used. In another example, an unsuccessful communication for a lower data rate modulation may be attributed to a higher data rate modulation scheme. Here, such attribution may infer that the higher data rate modulation scheme would have also been unsuccessful if it had been used.
