Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If rigid parameter settings are used for paging and broadcast message transmission, then system complexity is reduced, but flexibility and adaptability deteriorate
Solution Approach 1:
The patent applies dynamics by enabling the network device to dynamically select between a first parameter set and a second parameter set for paging and broadcast message transmission based on actual network conditions. This dynamic selection mechanism allows the system to adapt parameters such as time locations, time lengths, and subcarrier spacing according to varying requirements, thereby resolving the contradiction between maintaining low system complexity and achieving high flexibility.
Solution Approach 2:
The patent implements parameter changes by providing different parameter sets with varying configurations for paging and broadcast message transmission. The network device can switch between parameter sets depending on network conditions, allowing optimization of transmission parameters without increasing overall system complexity. This directly addresses the technical contradiction by enabling adaptability through parameter variability while maintaining manageable system structure.
2Adaptability or versatility
If dynamic parameter adjustment is implemented for paging and broadcast message transmission, then flexibility and adaptability are improved, but device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the parameter configuration into distinct parameter sets (first parameter set and second parameter set), each optimized for specific scenarios. This segmentation allows the system to manage complexity by organizing parameters into manageable groups rather than handling all parameters individually, thus enabling dynamic adjustment without proportionally increasing device complexity.
Solution Approach 2:
The patent implements universality by designing a framework where a single parameter set selection mechanism serves multiple functions: it optimizes paging transmission, optimizes broadcast message transmission, and adapts to different network conditions all through one unified approach. This multi-functionality reduces the need for separate complex control mechanisms for each function, thereby limiting the increase in device complexity while achieving high flexibility.
3Productivity
If fixed time locations and durations are used for paging transmission, then scheduling simplicity is maintained, but communication efficiency deteriorates under varying network conditions
Solution Approach 1:
The patent applies parameter changes by allowing the time locations and time lengths for paging and broadcast message transmission to vary based on the selected parameter set. Instead of fixed timing, the system can adjust these parameters dynamically, improving communication efficiency under varying network conditions while maintaining relatively simple scheduling through the use of pre-defined parameter sets.
