Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If frequency bands are allocated in a fixed manner, then interference between radiocommunication systems is limited, but the allocation cannot adapt to varying spectrum requirements of different systems
Solution Approach 1:
The patent implements dynamic frequency band allocation where the allocation is adapted according to space and time parameters. The system dynamically adjusts frequency band assignments based on the varying spectrum requirements of different radiocommunication systems, moving from static fixed allocation to dynamic adaptive allocation that responds to changing conditions.
Solution Approach 2:
The patent changes the allocation parameters from fixed to variable, allowing frequency band assignments to be modified based on spatial location and temporal conditions. This enables the system to adapt spectrum allocation to match the evolving requirements of different radiocommunication systems while maintaining interference limits.
2Adaptability or versatility
If frequency bands are allocated dynamically according to space and time, then spectrum requirements are met, but interference prediction becomes difficult
Solution Approach 1:
The patent performs preliminary determination of interference characteristics before finalizing frequency band allocations. By analyzing potential interference scenarios in advance and establishing allocation rules that prevent harmful interactions, the system can dynamically adapt allocations while maintaining predictable interference levels through pre-established constraints.
3Reliability
If a general method is implemented for allocating frequency bands to multiple radiocommunication systems, then interference can be minimized, but the complexity of the allocation system increases
Solution Approach 1:
The patent segments the frequency band allocation problem into manageable components, analyzing and allocating frequencies to different radiocommunication systems in a structured manner. By breaking down the complex multi-system allocation into systematic steps, the method reduces overall complexity while achieving interference minimization across all systems.

AI summary
The method involves modeling an allocation of a frequency band to a radio communication system e.g. Wireless fidelitytype network, by a three-dimensional block based on a frequency bandwidth and a coverage area of the system, and determining a distribution of the modeled blocks. A score is assigned to each block distribution based on a minimum frequency band having frequency bands of the blocks of the distribution. The block distribution having the score higher than a predetermined threshold is adopted to allocate the band to the system based on the adopted block distribution. Independent claims are also included for the following: (1) a computer program comprising instructions to perform a method of allocating a frequency band (2) a readable storage medium comprising instructions to perform a method of allocating a frequency band.
