Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing demand for wireless communication has led to congestion in radio frequency resources, necessitating improved frequency coordination technologies to ensure that non-incumbent devices, such as WiFi radios, do not interfere excessively with incumbent radios, particularly in the 6 GHz frequency band, while maintaining user experience.
Innovation Solution
A method and system for automated frequency coordination (AFC) that determines occasions for updating operating power and channel based on the states of the wireless communication interface, using an AFC server to provide available frequency spectrum and power constraints, allowing devices to adjust their operation to avoid interference and maintain performance.

Engineering Contradiction Analysis
1Object-affected harmful factors
If power constraints are imposed on non-incumbent radios to protect incumbent radios, then interference to incumbent radios is reduced, but wireless communication performance of non-incumbent devices deteriorates
Solution Approach 1:
The patent implements dynamic power adjustment by continuously monitoring wireless communication states (throughput, signal quality, connection status) and adapting power levels in real-time. The system transitions from static power constraints to dynamic power management, allowing non-incumbent devices to operate at higher powers when conditions permit and reduce power when interference risks arise or performance degrades.
Solution Approach 2:
The patent establishes a feedback mechanism that monitors wireless communication interface states including throughput, signal quality, and connection status. This feedback loop enables the system to detect performance degradation and adjust power levels accordingly, creating a closed-loop control system that balances interference protection with performance maintenance.
2Object-affected harmful factors
If frequency coordination technologies are improved to reduce interference, then incumbent radio protection is enhanced, but system complexity increases
Solution Approach 1:
The patent implements self-service mechanisms where non-incumbent devices autonomously monitor their own communication states and adjust their power levels without requiring complex centralized coordination. The device performs self-diagnosis of communication quality and self-regulation of power, reducing the burden on external frequency coordination systems.
Solution Approach 2:
The patent applies preliminary action by establishing power adjustment strategies in advance based on predetermined conditions and thresholds. The system pre-configures response actions for various communication states, enabling rapid adaptation without complex real-time decision-making processes.
3Object-affected harmful factors
If automated frequency coordination authentication is implemented, then interference management is improved, but processing overhead increases
Solution Approach 1:
The patent implements partial action by selectively applying AFC authentication and power adjustment mechanisms only when specific conditions are met, such as when communication quality degrades or interference thresholds are approached. Rather than continuously performing full authentication cycles, the system triggers adjustments only when necessary, reducing processing overhead while maintaining effective interference management.

AI summary
Disclosed are a method, a device and a computer program product for automated frequency coordination (AFC) authentication of a communication device. An AFC response, including information indicating available frequency spectrum and power constraints thereon for the communication device, may be received. An occasion for updating operating power on an operating channel, the operating channel, or the operating channel and the operating power thereon of a wireless communication interface of the communication device may be determined based on states of the wireless communication interface. The operating power on the operating channel, the operating channel, or the operating channel and the operating power thereon may be updated based at least in part on the power constraints on the available frequency spectrum at the occasion for updating.
