Solution Overview

Problem

Current spectrum sharing techniques rely on spectrum owners to report unused frequencies, which can lead to inefficiencies in utilizing available spectrum, especially in scenarios with high demand for mobile communications where prime spectrums like those under 6 GHz are underutilized.

Innovation Solution

A spectrum sharing framework architecture that includes a repository management component and a shared spectrum controller, which uses sensing information to identify available spectrum and manage access among different tiers of users, including incumbents, licensees, and unlicensed operators, without relying on owners to report unused bands.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If spectrum owners report unused frequencies manually, then spectrum sharing can occur, but spectrum utilization efficiency deteriorates due to underutilization of available spectrum

Engineering Contradiction:

Improvespectrum utilization efficiencyVSAvoidinformation about unused spectrum

Core Design Contradiction:

ProductivityVSLoss of information

Solution Approach 1:

The system employs sensing devices that automatically detect and report unused spectrum bands without requiring manual intervention from spectrum owners. The sensing devices self-organize into a distributed network that continuously monitors spectrum availability, eliminating the inefficiency of manual reporting while maintaining accurate information about unused frequencies.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

A centralized server acts as an intermediary between sensing devices and spectrum users. The server collects sensing data from distributed devices, processes this information to identify available spectrum bands, and makes allocation decisions. This intermediary coordinates the distributed sensing network and ensures efficient spectrum sharing without requiring direct communication between all system components.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If manual reporting of unused spectrum is used, then spectrum sharing is possible, but system complexity increases due to reliance on owner participation

Engineering Contradiction:

Improvespectrum sharing capabilityVSAvoidsystem operational complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Sensing devices automatically perform spectrum detection and reporting without requiring manual operation or intervention from spectrum owners. The devices self-configure and continuously monitor designated frequency bands, transforming a manually-dependent system into an autonomous one that maintains spectrum sharing capabilities while reducing operational complexity.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent replaces the manual mechanical process of spectrum owner reporting with an automated electronic sensing system. Distributed sensing devices use electronic signal processing to detect unused spectrum bands and communicate findings to a centralized server, substituting human-dependent mechanical reporting with automated electronic detection and communication systems.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Measurement precision

If sensing devices are distributed throughout the network, then spectrum detection accuracy improves, but device complexity increases

Engineering Contradiction:

Improvespectrum detection accuracyVSAvoidnetwork infrastructure complexity

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The spectrum detection function is segmented and distributed across multiple independent sensing devices rather than concentrated in a single centralized system. Each device independently monitors specific frequency bands in its local environment, providing geographically distributed measurements that collectively improve overall spectrum detection accuracy and coverage.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The centralized server provides universal functionality by serving multiple sensing devices and coordinating spectrum allocation across the entire network. The server aggregates data from all sensing devices, processes this information centrally, and makes allocation decisions that benefit all users, providing a multi-functional platform that manages the distributed sensing network efficiently.

Inventive Principle:

Principle #6Universality (Multi-functionality)
