Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems, particularly in emergency situations, face challenges with limited or unavailable terrestrial coverage, making it difficult to establish efficient bi-directional communication with telecommunication satellites, as existing solutions are often one-way and require complex location adjustments.
Innovation Solution
A data processing method that forms a virtual antenna array by pooling the radio resources of multiple terminals on the earth's surface, allowing for directional data transmission beams to be generated and selected based on performance criteria, enabling efficient bi-directional communication with telecommunication satellites.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If one-way transmission of predefined short messages is used, then implementation is simple, but communication efficiency is limited and cannot achieve bi-directional communication
Solution Approach 1:
The patent combines multiple terminals to form a virtual antenna array, merging their radio resources to enable bidirectional communication with satellites. This allows the system to achieve both implementation feasibility and high communication efficiency by pooling resources from multiple devices.
2Productivity
If terminal positions are adjusted to form virtual antenna array, then communication efficiency with satellite is improved, but implementation complexity increases
Solution Approach 1:
The system automatically determines guidance data based on satellite positions and terminal locations, enabling self-organization of the virtual antenna array without requiring complex manual configuration. The terminals autonomously adjust their positions based on received guidance data, reducing implementation complexity while maintaining high communication efficiency.
3Reliability
If repeated search for suitable location is required, then communication with satellite can be established, but time consumption increases
Solution Approach 1:
The system performs preliminary determination of satellite positions and terminal locations to generate guidance data before actual communication occurs. This preliminary action enables terminals to directly navigate to optimal positions without repeated searching, ensuring reliable communication establishment while minimizing time consumption.
4Productivity
If virtual antenna array is formed by pooling radio resources, then spectral efficiency is improved, but coordination between terminals becomes more complex
Solution Approach 1:
The system uses feedback mechanisms where terminals receive guidance data based on their positions and satellite locations, and automatically adjust their configurations. This feedback loop enables efficient coordination of multiple terminals forming the virtual antenna array, achieving high spectral efficiency while managing coordination complexity through automated control.

AI summary
A data processing method implemented by a first terminal belonging to a set of terminals including at least one other terminal. The method includes: transmitting guidance data to the at least one other terminal, the guidance data being configured to guide users of the terminals in adjusting their respective positions, so that the set of terminals forms a virtual antenna array configured to generate data transmission beams directed to a telecommunication satellite; and once the positions of the terminals are adjusted, selecting at least one data transmission beam to communicate with the satellite from beams that the virtual antenna array is capable of generating, the at least one selected beam satisfying a selection criterion referred to as “communication performance criterion”.
