Solution Overview

Problem

Cellular communication systems, such as beyond 4G LTE, face challenges due to unpredictable variations in data fidelity received by machine learning models, leading to inconsistent application performance and increased latency.

Innovation Solution

Training multiple machine learning models for different data fidelity levels and allocating resources based on Quality of Service (QoS) and model latency, using signal level and interference information from the application layer to select the appropriate model for execution.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a single ML model is trained to be robust over all data fidelities, then device complexity is reduced, but manufacturing precision (model accuracy) deteriorates

Engineering Contradiction:
Improvemodel complexityVSAvoidmodel accuracy
Core Design Contradiction:
Device complexityVSManufacturing precision

Solution Approach 1:

The patent segments the data fidelity space into multiple distinct fidelity levels (e.g., high, medium, low). For each fidelity level, a separate ML model is trained specifically on data with that fidelity characteristic. This segmentation allows each model to specialize in its designated fidelity range, achieving high accuracy for that specific condition without the complexity burden of a single universal model.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent implements local quality by training each ML model with data specifically tailored to its target fidelity level. Model A is trained exclusively on high-fidelity data, Model B on medium-fidelity data, and so on. Each model develops local expertise optimized for its specific fidelity condition, rather than attempting to generalize across all fidelities with a single model.

Inventive Principle:
Principle #3Local quality

2Manufacturing precision

If multiple ML models are trained for different data fidelity levels, then manufacturing precision (model accuracy) is improved, but device complexity increases

Engineering Contradiction:
Improvemodel accuracyVSAvoidmodel complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent introduces dynamic model selection based on the detected data fidelity level. The system continuously monitors the fidelity of incoming data and dynamically selects the appropriate pre-trained model for that fidelity level. This dynamic adaptation allows the system to maintain high accuracy across varying conditions while avoiding the need for a single complex universal model.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent introduces an intermediary component (fidelity detection module) that assesses the fidelity of incoming data and mediates the selection of the appropriate ML model. This intermediary layer simplifies the overall system architecture by providing a clear decision-making mechanism for model selection, rather than requiring complex interactions between multiple models.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Productivity

If resource allocation is based on QoS and model latency, then productivity is improved, but device complexity increases

Engineering Contradiction:
Improveapplication performanceVSAvoidresource allocation complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent utilizes QoS parameters and model latency metrics as key parameters for resource allocation decisions. By changing the allocation strategy to be parameter-driven (based on measurable QoS and latency characteristics), the system can objectively determine resource distribution across multiple models and fidelity levels, improving productivity through data-driven decisions rather than arbitrary allocation.

Inventive Principle:
Principle #35Parameter changes
