Solution Overview

Problem

The increasing number of radio wave operators poses challenges in arbitrating the use of radio waves, leading to inefficient allocation of radio resources, particularly due to the depletion of available frequency bands, necessitating effective utilization of spatio-temporally underutilized spectrum.

Innovation Solution

An information processor that acquires desired area information for a service using a secondary radio system sharing a frequency band with a primary system, calculates inter-area interference, and generates permitted area information to optimize radio resource usage without requiring pre-adjustment of base stations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If multiple operators use radio waves in the same frequency band, then spectrum utilization improves, but inter-operator interference increases

Engineering Contradiction:
Improvespectrum utilizationVSAvoidinter-operator interference
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent applies local quality by calculating and determining permitted areas for each operator on a spatial basis. Instead of uniformly allocating frequency bands, the system evaluates interference conditions locally in different geographic areas and assigns spectrum access rights accordingly. This allows spectrum utilization to be maximized in areas with low interference while protecting areas where interference would be harmful.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent implements dynamics by enabling dynamic spectrum access where operators can utilize frequency bands that are not currently being used by primary systems. The permitted area information is generated based on real-time or near-real-time interference calculations, allowing spectrum allocation to adapt dynamically to changing radio environment conditions and primary system usage patterns.

Inventive Principle:
Principle #15Dynamics

2Reliability

If base stations are physically installed to define service areas, then service coverage is established, but deployment cost and complexity increase

Engineering Contradiction:
Improveservice coverageVSAvoidbase station installation
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies copying by replacing physical base station installations with virtual permitted area information. Instead of requiring actual hardware deployment to define service boundaries, the system generates and distributes geographic information that represents where services can be provided. This virtual representation allows service coverage to be established and modified without physical infrastructure changes.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The patent substitutes the mechanical system of physical base station installation and adjustment with an information-processing system. The determination of service areas is achieved through calculation and generation of permitted area information based on interference models and primary system usage data, eliminating the need for physical measurement, installation, and adjustment of base stations.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Object-affected harmful factors

If manual arbitration of radio wave usage is performed between operators, then interference control is achieved, but processing time and resource allocation efficiency decrease

Engineering Contradiction:
Improveinterference controlVSAvoidarbitration processing time
Core Design Contradiction:
Object-affected harmful factorsVSLoss of time

Solution Approach 1:

The patent applies self-service by enabling the system to automatically determine permitted areas and allocate spectrum resources without manual arbitration. The interference calculation unit and permitted area generation unit work autonomously to evaluate interference conditions and assign frequency band usage rights. This automated process eliminates the need for time-consuming manual negotiations and decisions between operators.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent implements feedback by using information about primary system frequency band usage to dynamically adjust permitted area allocations. The system continuously monitors or receives updates about primary system operations and uses this feedback to recalculate interference conditions and modify spectrum access permissions accordingly, enabling rapid adaptation without manual intervention.

Inventive Principle:
Principle #23Feedback
