Solution Overview

Problem

Current inter-terminal coordinated communication technologies increase complexity and processing load for both network sides and terminals due to the need for joint signal processing and complete demodulation of information from other terminals.

Innovation Solution

A method where terminals share specific information to improve system performance, allowing terminals to obtain and process information from the network side independently, reducing the need for joint processing and demodulation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If terminals jointly process information and completely demodulate decode information from other terminals, then transmission quality is improved, but processing load and complexity of terminals increase

Engineering Contradiction:
Improvetransmission qualityVSAvoidprocessing complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent segments the information processing task by having terminals share only specific information (first information) rather than completely demodulating and decoding all information from other terminals. This selective sharing approach reduces processing complexity while maintaining transmission quality improvement through coordinated communication.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent extracts only the necessary first information from the complete signal processing task and shares this extracted information between terminals. This extraction approach eliminates the need for terminals to process entire information streams from each other, thereby reducing complexity while preserving the beneficial coordination effect.

Inventive Principle:
Principle #2Taking out (Extraction)

2Reliability

If network side jointly processes signals, then coordinated transmission is achieved, but information processing complexity of network side increases

Engineering Contradiction:
Improvecoordinated transmission capabilityVSAvoidnetwork side processing complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent enables terminals to perform self-service by sharing first information obtained from network side signals. This allows terminals to independently process and share necessary information without requiring the network side to perform complex joint processing, thereby achieving coordinated transmission while reducing network processing complexity.

Inventive Principle:
Principle #25Self-service

3Productivity

If terminals share specific information, then processing load is reduced, but system capacity and available space dimension may be limited

Engineering Contradiction:
Improveprocessing efficiencyVSAvoidsystem capacity
Core Design Contradiction:
ProductivityVSAdaptability or versatility

Solution Approach 1:

The patent changes the parameter of information sharing from complete information exchange to selective sharing of first information. This parameter change enables terminals to reduce processing load while maintaining sufficient system capacity through optimized information exchange strategies.

Inventive Principle:
Principle #35Parameter changes
