Solution Overview
Problem
Radio wave resources are becoming scarce, making it difficult to allocate new radio wave bands to radio systems, and existing cognitive radio technologies do not efficiently utilize white space due to the variety of radio systems involved.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If cognitive radio technology is used to allocate white space to multiple radio systems, then radio wave resource utilization is improved, but allocation efficiency deteriorates due to the variety of radio system types
Solution Approach 1:
The patent segments the heterogeneous radio systems into multiple groups based on their spectrum grant request schemes. The classification unit divides second radio systems into first and second groups according to whether they use a first scheme (individual parameter calculation) or a second scheme (group-based parameter calculation). This segmentation allows the communication control device to apply different allocation strategies to different system types, improving overall allocation efficiency while maintaining effective utilization of white space resources.
2Quantity of substance
If white space is allocated to various types of radio systems, then radio wave resource utilization is improved, but the complexity of allocation increases
Solution Approach 1:
The patent reduces allocation system complexity by segmenting radio systems into homogeneous groups. Instead of managing each radio system individually, the classification unit creates groups based on shared characteristics (spectrum grant request schemes). This allows the system to manage diversity through structured categorization, reducing the computational and operational complexity while still accommodating various radio system types effectively.
Solution Approach 2:
The patent implements a universal allocation framework that handles multiple radio system types through a common classification and calculation mechanism. The communication control device uses a unified process of acquiring spectrum grant requests, classifying systems into groups, and calculating communication parameters. This multi-functional approach allows the same system to efficiently manage diverse radio systems without requiring separate allocation mechanisms for each type.
3Measurement precision
If spectrum grant requests are processed individually for each radio system, then allocation precision is improved, but processing time increases
Solution Approach 1:
The patent segments the processing of spectrum grant requests into two pathways: individual processing for first radio systems requiring precise parameter calculation, and group-based processing for second radio systems where parameters are calculated for the entire group. This segmentation allows the system to maintain high precision where needed while reducing processing time for systems that can tolerate group-level parameters, thereby optimizing the trade-off between precision and processing efficiency.
Solution Approach 2:
The patent applies partial individualization by processing only certain radio systems (first group) with individual parameter calculation while using group-based calculation for others (second group). This partial action approach maintains sufficient precision for critical systems while accepting approximate parameters for less critical systems, reducing overall processing time without significantly compromising allocation effectiveness.
