Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a fixed and rigid protocol stack architecture is used, then implementation is simple, but network efficiency and resource utilization are suboptimal
Solution Approach 1:
The patent implements a dynamic protocol stack architecture where bandwidth parts can be flexibly configured and activated/deactivated based on traffic conditions. The MAC entity can dynamically switch between different bandwidth parts and configure secondary cells, allowing the system to adapt to varying network demands rather than being fixed in structure.
Solution Approach 2:
The patent segments the protocol stack into independent, configurable components including multiple bandwidth parts and secondary cells that can be individually activated or deactivated. This segmentation allows selective optimization of different parts of the protocol stack based on specific traffic requirements without affecting the entire system.
2Adaptability or versatility
If multiple technologies and devices are supported, then versatility is improved, but performance optimization becomes difficult
Solution Approach 1:
The patent creates a universal protocol stack architecture that can serve multiple device types and technology standards through configurable bandwidth parts and secondary cells. The same MAC entity can dynamically adapt its configuration to support different wireless devices, base station types, and traffic patterns, providing multi-functionality without sacrificing performance optimization capability.
3Productivity
If resources are allocated statically, then management is simple, but resource utilization is suboptimal
Solution Approach 1:
The patent implements feedback mechanisms where the MAC entity continuously monitors traffic conditions and dynamically adjusts bandwidth part activation and secondary cell configuration accordingly. This feedback-driven approach allows resources to be automatically allocated based on actual network demand, improving utilization while the automated nature of the process manages the complexity of resource allocation.
