3D Spectrum Authorization Using Height Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current frequency sharing schemes, such as those studied by the FCC, only consider two-dimensional positions for authorizing the use of frequency bands, leading to inefficient utilization of frequency bands in three-dimensional spaces, where interference may be minimal but authorization is not granted.
Innovation Solution
A system that includes an information processing apparatus capable of calculating and authorizing the use of shared frequency bands based on both position and height-related information, allowing wireless communication devices to use the band in usable three-dimensional spaces while minimizing interference with other systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If frequency band authorization is based only on two-dimensional position, then authorization process is simple, but frequency band utilization efficiency is low
Solution Approach 1:
The patent transitions from two-dimensional position-based authorization to three-dimensional spatial authorization by incorporating height information. The determination unit evaluates whether the terminal device's three-dimensional position (latitude, longitude, and height) falls within the exclusion zone, enabling more accurate interference assessment and improved frequency band utilization in vertical spaces
2Productivity
If frequency band use is authorized in three-dimensional spaces with minimal interference, then frequency band utilization efficiency improves, but authorization complexity increases
Solution Approach 1:
The system adds the height dimension to the authorization process, creating a three-dimensional exclusion zone model. The determination unit compares the terminal device's three-dimensional position against the exclusion zone boundaries, enabling authorization in spatial regions with minimal interference while maintaining a systematic and manageable authorization workflow
Solution Approach 2:
The determination unit serves as an intermediary that processes three-dimensional position information and compares it with exclusion zone data. This intermediary component simplifies the overall authorization process by handling the complex spatial calculations and providing clear authorization decisions based on whether the terminal device is within or outside the exclusion zone

AI summary
A system that acquires at least position information, height information and first priority information corresponding to a first wireless communication system (20), and second priority information corresponding to a second wireless communication system (20); determines a use condition for a shared frequency band shared between the first (20) and second (30) wireless communication systems based on the position information, the height information, the first priority information and the second priority information; and outputs a notification based on the determined use condition.
