Self-Degradation Adjustment for Dynamic Spectrum Allocation

The system introduces feedback by measuring actual channel quality after migration and using this information to adjust self-degradation estimates. The controller compares expected channel quality (based on self-degradation models) with actual measured quality, and refines the self-degradation value accordingly. This closed-loop feedback mechanism improves the precision of channel quality assessment over time, preventing unnecessary migrations while maintaining network effectiveness.

The patent replaces the simple mechanical comparison of channel quality values with a more sophisticated system that subtracts self-degradation effects. Instead of directly comparing CQI values, the system calculates adjusted channel quality by removing the component attributable to self-degradation, providing a more accurate representation of true channel conditions and enabling better migration decisions.

The system applies partial action by determining self-degradation values only when necessary for accurate channel quality assessment. Rather than continuously recalculating complex self-degradation models, the controller uses simplified estimation methods that provide sufficient accuracy for migration decisions, balancing computational effort with improvement in measurement precision.

The patent changes the parameters used in channel quality assessment by introducing self-degradation as a separate adjustable parameter. The controller modifies channel quality indicators by subtracting self-degradation values, transforming the assessment from a direct CQI comparison to an adjusted comparison that accounts for network-induced degradation. This parameter transformation improves accuracy without requiring fundamentally more complex system architecture.
