Solution Overview
Problem
The challenge of efficiently allocating unused radio spectrum to radio systems, particularly in environments with various radio systems having beam management functions, is not adequately addressed by conventional methods, leading to inefficiencies in radio resource utilization.
Innovation Solution
An information processing device that acquires capability information regarding beamforming of secondary radio systems, specifies interference calculation points, and performs interference calculations to optimize the allocation of radio resources, considering both horizontal and vertical beam patterns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional interference calculation methods are used without considering beamforming capability information, then the calculation process is simple, but radio resource allocation efficiency deteriorates in environments with beam management functions
Solution Approach 1:
The system performs preliminary acquisition of beamforming capability information from secondary radio systems before conducting interference calculation. This advance preparation allows the interference calculation to focus only on relevant parameters, improving efficiency without excessive complexity
Solution Approach 2:
The interference calculation process is segmented into distinct stages: acquiring beamforming capability information, specifying interference calculation points based on this information, and then performing the actual interference calculation. This segmentation allows each stage to be optimized independently
2Measurement precision
If interference calculation is performed at all specified points without filtering, then comprehensive interference assessment is achieved, but calculation time and processing load increase
Solution Approach 1:
Instead of performing interference calculation at all possible points, the system selectively specifies only certain interference calculation points based on beamforming capability information. This partial action approach maintains sufficient measurement precision while significantly reducing calculation time
Solution Approach 2:
The system changes the parameters used for specifying interference calculation points by incorporating beamforming capability information. This parameter change allows the system to identify and focus on the most critical calculation points, balancing comprehensiveness and efficiency
