Engineering Contradiction Analysis
1Quantity of substance
If frequency sharing techniques are used to allocate frequency bands to base stations, then the usage of limited frequency resources is improved, but the efficiency of frequency band usage deteriorates when interference thresholds are not met or communication needs are low
Solution Approach 1:
The patent implements dynamic frequency band allocation by continuously monitoring communication status information (data amount, terminal presence, interference levels) and adjusting the permitted frequency bands and transmission power values in real-time. This transforms the static frequency sharing mechanism into a dynamic system that adapts to changing communication needs, resolving the contradiction between resource allocation and usage efficiency.
Solution Approach 2:
The patent introduces a feedback mechanism where the communication control device receives communication status information from base stations and terminals, evaluates the actual usage conditions, and adjusts frequency band permissions accordingly. This closed-loop feedback system enables the network to respond to actual communication demands, improving frequency band usage efficiency while maintaining adequate resource allocation.
2Productivity
If a base station is permitted to use a wide frequency band, then the data transmission capacity is improved, but the interference with other systems increases
Solution Approach 1:
The patent dynamically changes the parameters of frequency band allocation (frequency range, transmission power values) based on real-time communication status information. When interference levels are low and communication demand is high, wider frequency bands and higher power values are permitted. When interference increases or communication needs decrease, the parameters are adjusted to reduce interference, thus resolving the contradiction between transmission capacity and interference.
3Area of stationary object
If transmission power values are maintained at high levels, then the coverage area is improved, but the energy consumption and interference increase
Solution Approach 1:
The patent implements dynamic adjustment of transmission power values based on monitored communication status information. When terminals are present and communication demand is high, higher transmission power values are permitted to expand coverage. When terminals are absent or communication needs are low, transmission power values are reduced to minimize energy consumption, resolving the contradiction between coverage area and energy loss.
