Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If RRUs are configured to expand network coverage, then coverage area is improved, but signal interference between cells increases
Solution Approach 1:
The patent segments cells by dynamically adjusting RRU configurations to create independent cell structures. When interference is detected, RRUs are reconfigured to form separate cells with distinct resource allocations, thereby reducing inter-cell interference while maintaining coverage area.
Solution Approach 2:
The patent implements dynamic RRU configuration adjustment based on real-time network conditions. The baseband unit monitors interference levels and dynamically reconfigures RRUs to combine or separate cells, making the network structure adaptive to changing conditions rather than static.
2Productivity
If more RRUs are deployed to improve network capacity, then network capacity is improved, but load imbalance between cells worsens
Solution Approach 1:
The patent employs dynamic load balancing through automated RRU reconfiguration. The baseband unit continuously monitors cell load conditions and dynamically adjusts RRU configurations to redistribute traffic, combining overloaded cells with underloaded adjacent cells to maintain balanced load distribution across the network.
Solution Approach 2:
The system implements feedback mechanisms where the baseband unit monitors cell load and interference conditions, then uses this information to make intelligent decisions about RRU configuration. This closed-loop control enables automatic optimization of load distribution based on real-time network state.
3Adaptability or versatility
If RRU configurations are made flexible to adapt to changing services, then adaptability is improved, but system complexity increases
Solution Approach 1:
The patent implements self-service automation where the baseband unit autonomously monitors network conditions, evaluates service requirements, and performs RRU configuration adjustments without manual intervention. This automated self-configuration reduces operational complexity while maintaining high adaptability to changing services.
Solution Approach 2:
The system transitions from static to dynamic configuration management, where RRU settings are automatically adjusted in real-time based on service demands and network conditions. This dynamic approach enables the network to adapt flexibly to varying services while the automation reduces the perceived complexity for operators.
