Base Station Position Control for Stable High-Frequency Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High-frequency radio communication systems, such as those above 6 GHz, face challenges in maintaining a stable communication state due to high signal loss and shielding issues, especially in environments where obstacles move, affecting devices like monitoring cameras that require high-definition video uploads.
Innovation Solution
A control apparatus that includes a shield detection unit, a terminal position candidate calculator, a line-of-sight determiner, and a base station movement controller, which acquires shield information, calculates optimal terminal positions, determines line-of-sight, and adjusts base station positions and directions to maximize communication quality.

Engineering Contradiction Analysis
1Speed
If high-frequency radio communication (Above-6 GHz) is used to achieve ultra-high-speed communication, then communication speed is improved, but communication stability deteriorates due to high signal loss and shielding
Solution Approach 1:
The system dynamically adjusts base station position and direction, and terminal position, based on real-time shield detection information. The control apparatus continuously monitors shield locations and recalculates optimal positions to maintain line-of-sight, making the communication system adaptive to changing environmental conditions rather than static
Solution Approach 2:
The system implements a feedback loop where shield detection information is continuously acquired, used to calculate position candidates, determine line-of-sight conditions, and adjust base station and terminal positions accordingly. This closed-loop control ensures communication stability by responding to environmental changes in real-time
2Device complexity
If base station and terminal positions are fixed, then device complexity is reduced, but communication quality deteriorates in environments with moving shields
Solution Approach 1:
The system transitions from fixed positioning to dynamic positioning where base station position, direction, and terminal position are continuously adjusted based on shield detection. The control apparatus calculates optimal positions in real-time and implements movements to maintain communication quality despite environmental changes
Solution Approach 2:
The system autonomously detects shields, calculates optimal positions, determines line-of-sight conditions, and adjusts base station and terminal positions without human intervention. The control apparatus self-manages the entire process of maintaining communication quality by responding to environmental changes

AI summary
A control apparatus for controlling a position and a direction of a base station, and a position of a specific terminal that wirelessly communicates with the base station in conjunction with each other, the control apparatus including: a shield detection information acquisition unit which acquires information obtained by detecting the shield; a specific terminal position candidate calculating unit which calculates a position candidate of the specific terminal on the basis of information obtained by detecting the shield; a line-of-sight determination unit which determines whether there is line-of-sight of the specific terminal from the base station for each of the position candidates of the specific terminal; and a base station movement control parameter calculating unit which determines a position of the specific terminal on the basis of a result of determination of the presence or absence of the line-of-sight and calculates a parameter indicating a position and a direction of the base station.
