Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the terminal device performs operational tasks in non-initial BWP without clear behavior guidelines, then device complexity increases and performance optimization becomes difficult, but following strict initial BWP behavior rules would limit adaptability to multiple BWP scenarios
Solution Approach 1:
The patent applies preliminary action by determining BWP similarity in advance before performing operational tasks. The terminal device compares radio configurations of different BWPs and identifies similar BWPs beforehand, storing this similarity information for later use. This pre-determination eliminates the need for complex real-time decisions during signal transmission, resolving the contradiction between adaptability and device complexity.
2Use of energy by moving object
If the terminal device performs measurements and transmissions in non-initial BWP based on initial BWP configurations, then power consumption increases, but not performing these tasks would reduce operational capability
Solution Approach 1:
The patent applies self-service by enabling the terminal device to autonomously determine whether to perform measurements and transmissions in non-initial BWP based on the pre-determined BWP similarity. When BWPs are identified as similar, the device automatically reuses configurations without additional measurements, reducing power consumption while maintaining transmission reliability through the similarity-based decision framework.
