Engineering Contradiction Analysis
1Productivity
If network coding protocols are implemented in existing communication systems, then data transmission efficiency can be improved, but radio resource utilization becomes suboptimal
Solution Approach 1:
The patent applies local quality by differentiating the treatment of NC PDUs based on their specific characteristics (systematic vs. non-systematic, innovation levels) and routing them to different RLC entities with appropriate resource allocations. This localized differentiation optimizes radio resource utilization for each PDU type while maintaining overall transmission efficiency.
Solution Approach 2:
The patent implements dynamics through adaptive routing decisions that adjust based on real-time conditions. The WTRU dynamically selects which RLC entity to route NC PDUs to based on factors like radio conditions, QoS requirements, and PDU characteristics, enabling optimal resource utilization under varying network conditions.
2Device complexity
If all NC PDUs are routed to the same RLC entity, then routing complexity is reduced, but radio resource efficiency deteriorates
Solution Approach 1:
Instead of uniform treatment, the patent applies local quality by identifying and differentiating PDU characteristics (systematic vs. non-systematic, innovation levels) and routing them to different RLC entities. This localized differentiation optimizes radio resource efficiency for each PDU type while managing complexity through characteristic-based classification.
Solution Approach 2:
The patent segments the routing process by dividing NC PDUs into different categories based on their characteristics and assigning them to different RLC entities. This segmentation allows optimized resource allocation for each segment while maintaining manageable complexity through structured classification criteria.
3Ease of operation
If NC PDUs are treated uniformly, then processing simplicity is maintained, but network coding benefits are not maximized
Solution Approach 1:
The patent applies local quality by differentiating PDU treatment based on characteristics such as systematic vs. non-systematic nature and innovation levels. This localized differentiation maximizes network coding benefits by applying appropriate routing strategies to each PDU type while maintaining processing simplicity through characteristic-based classification.
Solution Approach 2:
The patent utilizes parameter changes by routing decisions based on varying PDU characteristics (innovation levels, systematic vs. non-systematic). By changing routing parameters according to PDU properties, the system maximizes network coding benefits while keeping the processing logic simple and structured.
