Radio Device Conflict Detection for Multi-Device Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current radio technologies face challenges in controlling radio transmissions when multiple devices send conflicting control information to the same radio device, leading to operational conflicts due to resource overlaps and processing limitations, particularly in dual connectivity and device-to-device communication scenarios.
Innovation Solution
A method where a radio device receives control information from multiple sources, detects conflicts, and selects which operation to initiate based on priorities, discarding conflicting information and sending an indication of the conflict to the involved devices to adjust their behavior, thereby resolving operational conflicts and ensuring efficient resource utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple devices send control information to the same radio device, then the radio device can receive diverse control commands for dual connectivity and device-to-device communication, but operational conflicts arise due to resource overlaps and processing limitations
Solution Approach 1:
The radio device performs preliminary conflict detection by comparing resource requirements of control information from multiple devices before executing operations. This prevents resource conflicts by identifying overlapping operations in advance and selecting non-conflicting operations to execute
Solution Approach 2:
The radio device changes the parameter of operation selection by prioritizing certain control information over others based on conflict detection results. This allows the system to dynamically adjust which operations are executed based on resource availability and conflict status
2Loss of information
If the radio device processes all received control information, then complete control data is maintained, but processing limitations cause operational failures
Solution Approach 1:
The radio device extracts and identifies conflicting operations from the set of received control information by comparing resource requirements. Once conflicts are identified, the device selects only the non-conflicting operations for execution, effectively separating useful operations from problematic ones
Solution Approach 2:
The radio device discards conflicting control information that cannot be executed due to resource overlaps, while maintaining awareness of the conflict status. This allows the system to recover from potential failures by knowing which operations were not executed and why
3Reliability
If the radio device sends conflict indications to controlling devices, then the controlling devices can adjust their behavior, but additional signaling overhead is introduced
Solution Approach 1:
The radio device sends conflict indications back to the controlling devices that transmitted conflicting control information. This feedback mechanism allows controlling devices to adjust their behavior and resend appropriate control information, resolving conflicts through iterative communication

AI summary
A radio device (10-A) receives first control information (21) from a device (100-A). Further, the radio device (10-A) receives second control information (22) from another device (100-B). In response to detecting a conflict of an operation associated with the first control information (21) and an operation associated with the second control information (22), the radio device (10-A) selects between initiating the operation associated with the first control information (21) and initiating the operation associated with the second control information (22), and sends an indication of the conflict (23) to at least one of the device (100-A) and the other device (100-B).
