Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If higher frequency ranges (above 6 GHz) are used to increase data capacity, then data capacity is improved, but signal quality deteriorates due to increased susceptibility to multipath fading, scattering, atmospheric absorption, and interference

Engineering Contradiction:

Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent replaces conventional signal processing methods with machine learning-based approaches. Deep neural networks are trained to predict and compensate for channel effects such as multipath fading, scattering, and atmospheric absorption. The ML model processes received signals and predicts transmitted signals, enabling the system to maintain signal quality despite the challenges of higher frequency ranges.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent dynamically adjusts system parameters based on channel conditions. The ML model continuously learns from incoming signals and adapts its parameters (weights and biases) to optimize performance. This allows the system to compensate for varying channel characteristics caused by multipath effects, scattering, and atmospheric conditions, thereby maintaining reliable communication at higher frequencies.

Solution Approach 1:

The patent substitutes complex hardware solutions with software-based machine learning processing. Instead of requiring sophisticated hardware designed specifically for higher frequency ranges, the system uses standard hardware equipped with ML algorithms that can process and compensate for frequency-related challenges through software intelligence.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The ML-based processing system provides multiple functions using a single integrated approach. The same deep neural network infrastructure handles various tasks including signal prediction, channel compensation, and interference mitigation, reducing the need for specialized hardware components for each function.

Inventive Principle:

Solution Approach 1:

The patent replaces conventional signal processing algorithms with machine learning-based approaches. Deep neural networks are employed to predict transmitted signals from received signals, automatically learning complex patterns and distortions caused by multipath fading, scattering, and atmospheric effects without requiring manual algorithm design.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The ML model performs self-learning and self-optimization by continuously training on received signals. The system automatically adapts to changing channel conditions and distortion patterns without requiring external intervention or complex manual configuration, making information recovery easier despite increased distortion at higher frequencies.

Inventive Principle:

AI summary

Aspects describe federated learning for deep neural networks, DNNs, in a wireless communication system. A network entity directs (610) each user equipment, UE, in a set of UEs to form, using an initial machine-learning (ML) configuration, a respective deep neural network, DNN, that processes wireless network communications. The network entity requests (620), from each UE in the set of UEs, respective updated ML information generated by the respective UE using a training procedure and local input data. The network entity then receives (640), from at least some UEs in the set of UEs, the respective updated ML information determined by the respective UE. The network entity identifies (645) a subset of UEs in the set of UEs and determines (650) a common ML configuration for the subset of UEs. The network entity then directs (655) each UE in the subset of UEs to form an updated DNN using the common ML configuration.
