Wireless Device Autonomous Group Formation via Signal Strength
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication devices lack the ability to dynamically form groups based on user intent, as they rely on base stations to manage group formations, making it difficult to reflect user intentions in group communication settings.
Innovation Solution
A wireless communication device equipped with a reception unit for receiving group formation requests, a mode setting unit to set a group formation mode, a storage to store radio field strength and leader device identifiers, and a selection unit to choose the leader device with the strongest signal, allowing the device to autonomously select and join groups.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a base station forms a group of multiple wireless communication devices, then group communication can be established, but the wireless communication device cannot dynamically form a group in accordance with user intent
Solution Approach 1:
The wireless communication device autonomously performs group formation by selecting a leader device based on received signal strength without requiring base station intervention. The device sets a group formation mode, receives participation requests from multiple leader devices, stores signal strength information, and automatically selects the appropriate leader to join, enabling self-service group formation that reflects user intent.
2Ease of operation
If the device autonomously selects a leader device based on signal strength, then user intent can be reflected, but the device must store and process multiple parameters during group formation
Solution Approach 1:
The device preliminarily stores received signal strength information and leader device identifiers during the group formation mode before making the final selection. This preliminary data collection enables the device to autonomously evaluate and select the best leader based on pre-acquired signal strength measurements, simplifying the selection process while maintaining ease of operation.

AI summary
A wireless communication device includes: a reception unit configured to receive, by a first channel, a group formation request signal from a management device and a group participation request signal from each of leader devices; a mode setting unit configured to set, when the group formation request signal is received, a group formation mode during a first duration determined in advance; a storage configured to receive the group participation request signal and store a radio field strength when receiving the group participation request signal and an identifier of the leader device in an associated manner during the group formation mode; a selection unit configured to select, when the group formation mode is terminated, the leader device the radio field strength of which has a largest value; and a transmission unit configured to transmit, by a second channel, a group participation application signal to the selected leader device.
