Engineering Contradiction Analysis
1Quantity of substance
If cognitive radio technology is used to utilize temporal and spatial free radio waves (White Space), then radio wave resources can be secured for secondary wireless systems, but efficient distribution of these resources remains difficult due to varied usage patterns
Solution Approach 1:
The communication control apparatus implements a feedback mechanism by acquiring usage information from multiple second wireless systems, processing this information to determine interference margins, and notifying the systems of the determined margins. This closed-loop feedback enables dynamic adjustment of resource allocation based on actual usage patterns, resolving the contradiction between securing radio wave resources and achieving efficient utilization.
Solution Approach 2:
The system dynamically changes the interference margin parameter based on acquired usage information from different second wireless systems. By adjusting this parameter according to actual usage patterns and interference conditions, the system optimizes resource distribution efficiency while maintaining adequate resource availability for multiple systems.
2Quantity of substance
If frequency resources are allocated to second wireless systems in the frequency band used by first wireless system, then radio wave resource availability improves, but interference with primary system may occur
Solution Approach 1:
The communication control apparatus performs preliminary anti-action by acquiring usage information before allocating frequency resources, processing this information to determine appropriate interference margins, and notifying second wireless systems of these margins in advance. This preemptive approach prevents interference with the first wireless system while maintaining frequency resource availability for secondary systems.
Solution Approach 2:
The communication control apparatus acts as an intermediary between the first wireless system and second wireless systems. It acquires usage information from second systems, processes this information to determine interference margins, and notifies the systems accordingly, thereby mediating the coexistence and preventing harmful interference while maintaining resource availability.
3Productivity
If usage information from multiple second wireless systems is acquired and processed, then resource distribution efficiency improves, but system complexity increases
Solution Approach 1:
The communication control apparatus implements a universal processing mechanism that handles usage information from multiple different second wireless systems through a single integrated process. This multi-functional approach improves resource distribution efficiency across all systems while avoiding the need for separate processing mechanisms for each system, thereby limiting the increase in overall system complexity.
