Engineering Contradiction Analysis
1Ease of operation
If autonomous resource selection mode is used, then terminal device can independently select SL resources, but SL resource utilization is not ideal
Solution Approach 1:
The terminal device monitors SL resource utilization metrics and channel conditions, then uses this feedback information to dynamically adjust resource selection decisions. The network device also provides feedback regarding resource allocation recommendations, creating a closed-loop system that improves resource utilization while maintaining autonomous selection capability.
Solution Approach 2:
The terminal device changes selection parameters based on monitored conditions, including utilization rate thresholds, communication quality metrics, and carrier attributes. By dynamically adjusting these parameters rather than using fixed selection criteria, the system achieves better resource utilization while preserving autonomous operation.
2Productivity
If multiple factors are considered for SL resource determination, then resource utilization improves, but determination complexity increases
Solution Approach 1:
The resource determination process is divided into separate functional modules: a monitoring module that collects utilization metrics and channel conditions, an evaluation module that assesses candidate resources based on multiple factors, and a selection module that chooses the optimal resource. This segmentation allows complex multi-factor analysis to be performed in an organized manner without overwhelming the terminal device.
Solution Approach 2:
The patent introduces an intermediary evaluation mechanism that processes multiple input factors (utilization rate, communication quality, carrier attributes) through a standardized assessment framework before producing a resource selection decision. This intermediary layer simplifies the overall determination process by providing a structured approach to evaluating multiple factors simultaneously.
