Communication Control Apparatus Dynamic Interference Margin Adjustment

The patent segments the interference evaluation process into two parts: (1) a simplified initial evaluation that provides quick results, and (2) a detailed refinement evaluation that is only performed when needed. This segmentation allows the system to handle multiple secondary systems efficiently by avoiding full quadratic calculations for all cases, thus resolving the contradiction between resource utilization and calculation complexity.

The patent implements dynamic adjustment of evaluation depth based on system conditions. When the number of secondary systems is small or interference levels are low, a simplified evaluation is used. When secondary systems increase or interference approaches thresholds, the system dynamically switches to more detailed evaluation. This dynamic approach maintains efficiency while ensuring accuracy when necessary.

The patent performs preliminary simplified interference evaluation before final power allocation decisions. This preliminary action provides an initial assessment that is computationally efficient, allowing the system to quickly determine whether detailed evaluation is necessary. By performing this preliminary check first, the system avoids time-consuming comprehensive evaluations when they are not strictly necessary, thus maintaining timeliness while preserving reliability when needed.

The patent implements a feedback mechanism where the results of simplified evaluation feed into the decision of whether to perform detailed evaluation. If the simplified evaluation shows that interference levels are well within acceptable ranges, the system feedback-indicates that detailed evaluation can be skipped. If the simplified evaluation shows approaching thresholds, the system triggers detailed evaluation. This feedback loop ensures both timeliness and reliability.

The patent applies different interference avoidance margins to different secondary systems based on their specific characteristics, locations, and interference potential. Instead of using a uniform conservative margin for all secondary systems, the system calculates and applies localized margins tailored to each system's actual impact on primary systems. This local quality approach ensures adequate protection where needed while allowing higher power allocation where interference risk is lower, thus resolving the contradiction between protection and utilization.

The patent dynamically adjusts the interference avoidance margin parameter based on real-time system conditions, including the number of active secondary systems, their transmit powers, locations, and the observed interference levels. This parameter change allows the system to optimize the balance between primary system protection and secondary system resource utilization, applying tighter margins only when necessary and more permissive margins when conditions allow, thereby improving overall productivity without compromising reliability.
