Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the strategy of blanking all affected unit transmission resources is adopted to ensure reliable transmission, then transmission reliability is improved, but transmission resource utilization deteriorates
Solution Approach 1:
The patent applies local quality by differentiating the treatment of unit transmission resources based on their specific impact factors. Instead of uniformly blanking all affected resources, the system evaluates each resource's impact factor (ratio of on/off transient period to resource duration) and applies appropriate configuration strategies: resources with impact factor ≤ 0.5 are configured for transmission, while those with impact factor > 0.5 are blanked. This localized differentiation optimizes both reliability and resource utilization.
Solution Approach 2:
The patent introduces the impact factor as a new parameter to determine transmission configuration. By calculating the ratio between the on/off transient period and the unit transmission resource duration, the system dynamically adjusts configuration decisions. This parameter-based approach replaces the binary blanking strategy with a nuanced configuration method that considers the specific characteristics of each transmission resource.
2Adaptability or versatility
If frequent uplink and downlink switching is implemented to increase communication flexibility, then communication adaptability is improved, but transmission resource waste increases due to on/off transient periods
Solution Approach 1:
The patent introduces the impact factor parameter to quantify the relationship between on/off transient period and unit transmission resource duration. By calculating this ratio, the system can make informed decisions about whether to configure or blank each resource, thereby reducing waste while maintaining the flexibility of frequent switching. The parameter enables dynamic adaptation to different switching frequencies and resource types.
Solution Approach 2:
Instead of completely blanking all affected resources during on/off transient periods, the patent applies partial action by configuring resources where the impact factor indicates acceptable performance (≤ 0.5). This partial configuration approach avoids excessive resource abandonment while still protecting transmission reliability in critical cases, thus reducing overall resource waste.
3Device complexity
If all affected unit transmission resources are blanked to simplify resource management, then device complexity is reduced, but data transmission rate deteriorates
Solution Approach 1:
The patent introduces the impact factor as a simple calculation (ratio of transient period to resource duration) that provides a clear decision criterion. This parameter-based approach simplifies resource management by replacing complex multi-factor analysis with a single threshold-based rule: configure if impact factor ≤ 0.5, blank if impact factor > 0.5. The simplicity of this parameter maintains low device complexity while improving transmission rate.
Solution Approach 2:
The patent implements a dynamic resource configuration strategy where the decision to configure or blank each unit transmission resource is made individually based on its specific impact factor. This dynamic approach allows the system to adapt to varying conditions (different frequency ranges, sub-carrier spacings, and transient periods) without requiring complex centralized control, thus maintaining simplicity while maximizing transmission rate.
