Solution Overview

Problem

Existing wireless communication networks face interference issues due to increased demand for mobile broadband access, leading to degraded performance, and existing cross-node training methods for channel state feedback reveal proprietary information, requiring separate encoders and decoders for each device combination.

Innovation Solution

Implement UE-driven sequential training to generate a shared encoder and decoder using a sequential training dataset, allowing multiple devices to use a universal decoder without revealing proprietary designs, by training a decoder based on channel state information data and transmitting a sequential training dataset to a network node.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If cross-node training methods are used for channel state feedback, then encoder and decoder compatibility is improved, but proprietary information is revealed

Engineering Contradiction:
Improveencoder and decoder compatibilityVSAvoidproprietary information
Core Design Contradiction:
Adaptability or versatilityVSLoss of information

Solution Approach 1:

The patent introduces a third-party training data generator that acts as an intermediary between different device vendors. This intermediary collects channel state information from multiple nodes and generates training datasets without requiring direct sharing of proprietary encoder/decoder models. The training data includes encoded feedback and corresponding channel state information, enabling cross-node training while protecting vendor-specific proprietary information through indirect data sharing rather than direct model exchange.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Loss of information

If separate encoders and decoders are used for each device combination, then proprietary information is protected, but device complexity increases

Engineering Contradiction:
Improveproprietary information protectionVSAvoidnumber of encoders and decoders
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The patent implements universal encoders and decoders that can function across multiple device combinations and vendor platforms. Instead of requiring separate encoders for each device pair, the system trains a single universal encoder that processes channel state feedback from various nodes and a universal decoder that reconstructs the feedback for different receiving devices. This multi-functional approach maintains proprietary information protection through vendor-specific training data while reducing overall system complexity by sharing common encoding/decoding infrastructure.

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

3Productivity

If more UEs access wireless networks, then mobile broadband demand is met, but interference increases and performance degrades

Engineering Contradiction:
Improvemobile broadband accessVSAvoidinterference
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent implements a feedback mechanism where UEs transmit channel state information about their received signals back to the network. This feedback data is then used to train encoders and decoders that can better compensate for interference conditions. By continuously monitoring and feeding back channel quality information, the system adapts its encoding/decoding parameters to optimize performance under varying interference levels, allowing more UEs to access the network with improved signal quality despite increased interference.

Inventive Principle:
Principle #23Feedback
