Solution Overview

Problem

Current wireless communication systems face challenges in efficiently managing channel allocation and interference in guard bands, leading to unsatisfactory performance and interference with adjacent systems, particularly in IoT applications using licensed bands.

Innovation Solution

The system classifies channels based on interference levels from adjacent systems, allowing for efficient communication by allocating channels with determined classes of interference, enabling precise power control and modulation schemes to minimize interference and optimize data transmission.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If channels are allocated in guard bands to increase spectrum utilization, then productivity is improved, but interference with adjacent systems increases

Engineering Contradiction:
Improvespectrum utilizationVSAvoidinterference with adjacent systems
Core Design Contradiction:
ProductivityVSObject-generated harmful factors

Solution Approach 1:

The patent applies local quality by classifying guard band channels into different types (first type and second type) based on their interference characteristics. First type channels are allocated when interference with adjacent systems is acceptable, while second type channels are allocated when interference must be minimized. This localized differentiation allows the system to optimize spectrum utilization in specific frequency regions while maintaining protection for adjacent systems in other regions.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent changes the parameter of channel allocation by introducing channel type classification and corresponding allocation rules. The system dynamically selects which type of channel to allocate based on current interference conditions and system requirements, transforming a static allocation approach into a dynamic parameter-based strategy that balances productivity and interference control.

Inventive Principle:
Principle #35Parameter changes

2Ease of operation

If channel allocation is simplified to ease operation, then ease of operation is improved, but interference control precision deteriorates

Engineering Contradiction:
Improvechannel allocation managementVSAvoidinterference control precision
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

The patent segments the channel allocation process into distinct types (first type and second type channel allocation) with specific rules for each. This segmentation allows the system to manage complexity by creating standardized allocation procedures for different scenarios, making the overall operation easier while maintaining precise interference control through the structured classification framework.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces channel type classification as an intermediary layer between the simple allocation decision and the complex interference control requirements. This intermediary structure provides a systematic framework that simplifies operation by offering clear allocation rules for each channel type, while simultaneously achieving precise interference control through the differentiated treatment of first and second type channels.

Inventive Principle:
Principle #24Intermediary (Mediator)
