Solution Overview

Problem

Current machine learning implementations in radio access networks face challenges in efficiently processing and transmitting data between user equipment and artificial neural networks, particularly in selecting appropriate input layers and configuring parameters for effective radio resource management.

Innovation Solution

A distributed machine learning system comprising a first apparatus with a receiver, processor, and transmitter configured to receive and process input data from user equipment, determine inputs for artificial neural networks, and transmit outputs, while a second apparatus processes these outputs for radio resource management, using configuration commands and training information to select input layers and configure parameters.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If machine learning is implemented in radio access networks, then radio resource management performance is improved, but data processing complexity and system configuration requirements increase

Engineering Contradiction:
Improveradio resource management performanceVSAvoiddata processing complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The artificial neural network is divided into multiple input layers (first input layer, second input layer, etc.), each processing different types of data from user equipment. This segmentation allows the system to handle complex data processing by breaking it down into manageable stages, improving both performance and configurability without overwhelming complexity

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system dynamically selects which input layers to activate and which parameters to configure based on real-time conditions and configuration commands. This dynamic approach allows the neural network to adapt to varying network conditions, improving resource management performance while managing complexity through selective activation rather than processing all data simultaneously

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If multiple input layers and parameters are configured for the artificial neural network, then machine learning effectiveness is improved, but system configuration and operation complexity increase

Engineering Contradiction:
Improvemachine learning effectivenessVSAvoidsystem configuration complexity
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The interface is designed to receive multiple types of configuration commands (first configuration command, second configuration command, etc.) that can selectively enable different input layers and parameters. This universal interface simplifies operation by providing a single point of control for managing the complex neural network configuration, allowing operators to activate specific layers based on needs without configuring everything manually

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

Solution Approach 2:

The system includes feedback mechanisms where configuration commands are received, processed, and the results are transmitted back. This feedback loop allows the system to learn from configuration outcomes and adjust operations accordingly, making the complex multi-layer neural network easier to manage through automated adaptation rather than manual reconfiguration

Inventive Principle:
Principle #23Feedback

3Measurement precision

If data is processed through multiple layers of the artificial neural network, then radio resource management accuracy is improved, but data transmission time and processing delay increase

Engineering Contradiction:
Improveradio resource management accuracyVSAvoiddata processing delay
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The system processes data through multiple input layers selectively rather than always processing through all layers. Based on configuration commands and network conditions, the system can process data through only the necessary layers to achieve required accuracy, reducing unnecessary processing delay while maintaining sufficient measurement precision for effective resource management

Inventive Principle:
Principle #16Partial or excessive action
