Engineering Contradiction Analysis
1Productivity
If fixed radio resource allocation is used between inner and outer cells, then device complexity is reduced and ease of operation is improved, but network capacity utilization deteriorates and resource sharing efficiency worsens
Solution Approach 1:
The patent implements dynamic resource allocation where the pool of radio resources is flexibly distributed between inner and outer cells based on real-time traffic demand. The system transitions from fixed allocation to dynamic adjustment, allowing the resource distribution to adapt to changing conditions while maintaining manageable complexity through centralized control.
Solution Approach 2:
The patent creates a universal resource pool that serves both inner and outer cells, allowing the same radio resources to be shared and allocated to different cells based on demand. This multi-functional approach enables a single resource pool to fulfill multiple cell serving requirements, improving overall network capacity utilization.
2Reliability
If separate radio transceivers are used for inner and outer cells, then reliability is improved and ease of operation is enhanced, but resource sharing capability deteriorates and power efficiency worsens
Solution Approach 1:
The patent merges the radio resources of inner and outer cells into a single shared pool, enabling flexible allocation and efficient sharing between cells. This combining approach maintains service reliability through diverse resource availability while dramatically improving resource sharing capability and power efficiency.
Solution Approach 2:
The system implements feedback mechanisms to monitor traffic demand in both inner and outer cells, using this information to dynamically adjust resource allocation from the shared pool. This feedback-driven approach ensures reliable service by adapting resource distribution to actual network conditions and demand patterns.
3Use of energy by moving object
If RF output power is fixed for each cell, then ease of operation is improved and device complexity is reduced, but power efficiency deteriorates and network capacity utilization worsens
Solution Approach 1:
The patent implements dynamic power allocation from a shared RF output pool, where the available power is flexibly distributed between inner and outer cells based on real-time traffic demand. This dynamic approach dramatically improves power efficiency by ensuring power is allocated only where needed, while centralized control manages the complexity of power distribution.
