Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies have not effectively utilized secondary channels in wireless systems to improve frequency utilization efficiency, particularly in environments where diverse wireless systems coexist and radio wave resources are depleted.
Innovation Solution
A communication control apparatus and method that transitions a channel used by a target communication apparatus from a primary channel to a secondary channel when detected as being used by a protected system, based on the usage conditions of the secondary channel assigned to that apparatus.

Engineering Contradiction Analysis
1Productivity
If secondary channels are assigned to communication apparatuses, then frequency utilization efficiency is improved, but channel allocation complexity increases
Solution Approach 1:
The patent implements dynamic channel allocation where communication apparatuses can transition between primary and secondary channels based on real-time detection of protected systems. The channel assignment is not fixed but adapts dynamically according to the operational state of the environment, allowing the system to optimize frequency utilization while managing complexity through automated decision-making.
Solution Approach 2:
The system employs feedback mechanisms where the detection unit continuously monitors for protected systems, and the processing unit adjusts channel assignments based on this feedback. When a protected system is detected, the apparatus automatically transitions from primary to secondary channel, creating a closed-loop control system that balances frequency utilization efficiency with interference protection.
2Reliability
If primary channels are used exclusively, then protection of existing systems is ensured, but frequency utilization efficiency decreases
Solution Approach 1:
Instead of requiring exclusive use of primary channels, the system allows communication apparatuses to use secondary channels when protected systems are not present. This partial action approach enables the system to utilize available spectrum resources more efficiently while maintaining protection for existing systems when needed, rather than enforcing full exclusivity.
Solution Approach 2:
The system changes the operational parameters of channel assignment based on detection results. When a protected system is detected, the channel mode parameter changes from primary to secondary. This parameter change allows the system to adapt its behavior dynamically, balancing the need for protection with the opportunity for efficient spectrum utilization.
3Productivity
If channel transitions from primary to secondary are implemented, then frequency utilization efficiency is improved, but system response time increases
Solution Approach 1:
The detection unit continuously monitors the environment in advance to detect protected systems before they cause interference. This preliminary detection and preparation allows the system to proactively transition channels when needed, reducing the response time compared to reactive approaches where channel changes occur only after interference is detected.
