Dual-Mode Terminal for Autonomous Positioning Coverage Expansion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In radio communication systems, insufficient Responder terminals limit positioning coverage, requiring manual user configuration to expand coverage, thereby increasing user burden.
Innovation Solution
A terminal capable of functioning as both an Initiator and Responder, using control means to exchange frames with neighboring terminals to estimate position information and switch roles, allowing multiple terminals to operate as Responder terminals without user burden.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If manual user configuration is used to prepare Responder terminals, then positioning coverage can be expanded, but user burden increases
Solution Approach 1:
The terminal automatically determines whether to function as an Initiator or Responder based on its current position information status, without requiring manual user configuration. The control means autonomously manages the terminal's role switching to expand positioning coverage while eliminating user burden.
Solution Approach 2:
The terminal dynamically switches between Initiator and Responder functions based on real-time positioning needs. The control means enables flexible role transition, allowing the terminal to adapt its behavior according to whether position information is already acquired or needs to be obtained.
2Measurement precision
If more Responder terminals are deployed, then positioning accuracy improves, but system complexity increases
Solution Approach 1:
Each terminal is designed with dual functionality, capable of operating as both Initiator and Responder. This multi-functionality reduces the need for dedicated specialized terminals, thereby improving positioning accuracy through more available terminals while avoiding increased system complexity.
Solution Approach 2:
Instead of designating specific terminals as fixed Responder nodes, the system inverts the approach by allowing any terminal to become a Responder when needed. This role reversal based on situational needs optimizes positioning accuracy without requiring complex predetermined system architecture.

AI summary
A terminal (10) includes an Initiator functional unit (13) for acquiring information to be used for estimating position information of the terminal by performing frame exchange with a neighboring Responder terminal, a Responder functional unit (14) for providing the information to be used for estimating the position information of the Initiator terminal by performing the frame exchange with a neighboring Initiator terminal, and a control unit (12) for controlling the Initiator functional unit (13) and the Responder functional unit (14). The control unit (12) estimates the position information of the terminal (10) based on the information acquired by controlling the terminal (10) to function as the Initiator terminal using the Initiator functional unit (13) and by controlling the terminal (10) to exchange frames with the neighboring Responder terminal, and then controls the terminal (10) to function as the Responder terminal using the Responder functional unit (14) and the position information.
