Solution Overview
Problem
In scenarios with multiple secondary systems, accurately controlling transmission power to prevent accumulative interference with primary systems is challenging, leading to increased calculation costs and load on control nodes.
Innovation Solution

Engineering Contradiction Analysis
1Reliability
If accurate transmission power control is implemented for all secondary systems to prevent accumulative interference with primary systems, then interference prevention capability is improved, but calculation cost and control node load increase
Solution Approach 1:
The patent segments secondary systems into two distinct groups based on their distance from the primary system: a first group within a prescribed distance threshold and a second group beyond the threshold. This segmentation allows different power allocation methods to be applied to each group, reducing overall calculation complexity while maintaining interference prevention for the critical first group.
Solution Approach 2:
The patent applies different quality levels of power allocation methods to different groups of secondary systems. The first group (closer to primary system) receives more accurate, computationally intensive power allocation to ensure interference prevention, while the second group (farther away) receives simpler, less computationally demanding power allocation since their interference impact is naturally reduced by distance.
2Productivity
If simple power allocation methods are used for secondary systems, then calculation load is reduced, but interference control precision deteriorates
Solution Approach 1:
The patent divides secondary systems into two groups based on distance from the primary system. For the first group (within threshold distance), accurate power allocation methods are applied to maintain interference control precision. For the second group (beyond threshold), simpler methods are acceptable since distance naturally reduces their interference impact, thus improving overall calculation efficiency.
Solution Approach 2:
Different precision levels of power allocation are applied locally to different groups. The first group receives high-precision power allocation matching their higher interference risk, while the second group receives lower-precision allocation sufficient for their lower risk profile, optimizing the balance between precision and efficiency.

AI summary
There is provided a doing apparatus including a communication control device including a power allocation unit configured to allocate transmission power for secondary use of a frequency channel protected for a primary system to a secondary system. The power allocation unit switches power allocation methods between a first group of secondary systems of which a distance from the primary system is less than a prescribed threshold and a second group of secondary systems of which a distance from the primary system exceeds the prescribed threshold.
