Radio Device Transition Coordination for Many-to-Many Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing digital radio communication protocols lack effective support for many-to-many communication, where a group of devices can communicate with each other simultaneously, which is necessary for applications like group audio communications.
Innovation Solution
A method and system that enables radio devices to coordinate transitions between different broadcasters, allowing multiple devices to receive and decode radio signals from multiple sources without establishing complex two-way communications, using a pseudo radio device approach to simplify transitions and avoid time overlaps, thereby achieving robust and efficient many-to-many communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If one-to-one unicast connections are used for radio communication, then communication reliability between two devices is improved, but the system cannot support many-to-many communication where multiple devices communicate simultaneously
Solution Approach 1:
The patent applies universality by enabling radio devices to function in multiple roles - they can act as broadcasters, receivers, or both simultaneously depending on the communication mode required. The system supports both unicast and many-to-many communication modes through the same hardware infrastructure, making the communication protocol versatile enough to handle different communication patterns without requiring separate dedicated systems
2Adaptability or versatility
If broadcast functionality is added to enable one-to-many communication, then the ability to communicate with multiple devices is improved, but there is still limited support for many-to-many communication where devices can both broadcast and receive
Solution Approach 1:
The patent applies dynamics by allowing radio devices to dynamically switch between broadcasting and receiving modes based on real-time communication needs. Devices can transition from being receivers to broadcasters and vice versa, enabling flexible many-to-many communication where roles are not fixed but adapt to the current communication scenario, thereby achieving reliable multi-device interaction
3Adaptability or versatility
If numerous two-way communications are established between each device for many-to-many communication, then complete communication coverage is improved, but the system complexity and resource requirements increase substantially
Solution Approach 1:
The patent applies segmentation by dividing the many-to-many communication process into separate broadcasting and receiving phases. Instead of establishing complex continuous two-way connections between all device pairs, the system segments communication into discrete broadcast events where one device transmits and others receive, significantly reducing protocol complexity while maintaining complete communication coverage across the group
Data Source
AI summary
A method of operating a radio communication system comprising a group of radio devices is provided. The method comprises a first radio device of the group broadcasting a radio signal in which data are encoded; radio devices of the group receiving the radio signal from the first radio device and decoding the data encoded therein; and a second radio device of the group broadcasting a radio signal in which data are encoded; coordinating at least one radio device of the group to transition from receiving the radio signal broadcast by the first radio device and decoding the data encoded therein to receiving the radio signal broadcast by the second radio device of the group and decoding the data encoded therein; and radio devices of the group receiving the radio signal from the second radio device and decoding the data encoded therein.
