Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If flexibility is increased to serve a wide range of use cases and applications, then the system can accommodate diverse communication needs, but signaling overhead increases
Solution Approach 1:
The resource pool is segmented into multiple resource structures with different configurations (e.g., different time-frequency resources, different payload sizes). Instead of using a single uniform resource structure for all control signaling, the system divides the resource space into discrete selectable options, allowing flexible adaptation without requiring extensive signaling to describe each individual resource allocation.
Solution Approach 2:
The patent implements dynamic resource structure selection where the specific resource structure used for control signaling is chosen based on current communication conditions, traffic type, and service requirements. This dynamic selection mechanism allows the system to adapt flexibly to different use cases while maintaining efficient resource utilization and minimizing overhead through context-aware resource allocation.
2Productivity
If resource structure selection is made dynamic based on signaling characteristics, then flexibility and efficiency are improved, but system complexity increases
Solution Approach 1:
Multiple resource structures are pre-configured and made available in the resource pool before communication occurs. Each resource structure is designed with specific characteristics suitable for different signaling scenarios. This preliminary preparation eliminates the need for complex real-time resource configuration decisions, reducing system complexity while maintaining dynamic adaptability through pre-planned resource options.
Solution Approach 2:
The patent changes key parameters of the resource structures (such as time-frequency allocation patterns, payload sizes, and resource block configurations) to create a diverse set of selectable options. By varying these parameters across different resource structures, the system achieves flexibility and efficiency for different signaling characteristics without requiring complex selection logic, as the parameter variations naturally accommodate different service requirements.
