Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If secondary cell component carriers are distributed uniformly across all remote coverage areas, then coverage is provided to all areas, but capacity utilization is inefficient and power consumption increases
Solution Approach 1:
The patent applies local quality by selectively distributing secondary cell component carriers to specific remote units based on their transmission power demand and signal quality characteristics. Instead of uniform distribution, the system identifies remote units with higher capacity demand and routes secondary carriers only to those units, optimizing both capacity utilization and power consumption locally where needed.
Solution Approach 2:
The system dynamically determines the routing of secondary cell component carriers based on real-time or near-real-time assessment of transmission power demand and signal quality at different remote units. This dynamic adaptation allows the system to optimize capacity allocation according to changing network conditions, ensuring efficient resource utilization without unnecessary power consumption in low-demand areas.
2Adaptability or versatility
If secondary cell component carriers are distributed uniformly, then all remote units receive the same capacity, but capacity allocation does not adapt to transmission power demand
Solution Approach 1:
The patent implements local quality by tailoring capacity allocation to the specific characteristics of each remote unit. The system assesses transmission power demand and signal quality at individual remote units and routes secondary cell component carriers accordingly, ensuring that capacity is allocated efficiently based on local network conditions rather than applying a uniform distribution approach.
Solution Approach 2:
The system incorporates feedback mechanisms where the network controller continuously monitors transmission power demand and signal quality at remote units. Based on this feedback, the controller dynamically adjusts the routing of secondary cell component carriers to optimize capacity utilization, ensuring that capacity allocation adapts to actual network conditions and demand patterns.
3Productivity
If secondary cell component carriers are selectively routed based on transmission power demand, then capacity utilization improves, but system complexity increases
Solution Approach 1:
The system performs preliminary assessment of transmission power demand and signal quality characteristics at remote units before routing secondary cell component carriers. By pre-characterizing the network conditions at different remote units, the system can make informed routing decisions without requiring complex real-time calculations, thus improving capacity utilization while managing control complexity through advance preparation.
Solution Approach 2:
The network controller autonomously performs the assessment and routing decisions for secondary cell component carriers based on predefined criteria for transmission power demand and signal quality. This self-service approach allows the system to optimize capacity utilization automatically without requiring manual intervention or complex external control mechanisms, thereby managing system complexity through automated decision-making.
4Ease of operation
If uniform distribution of secondary cell carriers is used, then implementation is simple, but signal quality cannot be optimized for high-demand areas
Solution Approach 1:
The patent applies local quality by optimizing signal quality at specific remote units that have higher transmission power demand. The system routes secondary cell component carriers selectively to these units based on their signal quality characteristics, ensuring that signal quality is optimized where needed while maintaining simpler implementation through automated routing decisions rather than manual configuration.
