Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single uplink resource is allocated for uplink data transmission, then device complexity is reduced, but communication latency increases and reliability decreases
Solution Approach 1:
The patent segments the uplink resource allocation into multiple independent uplink resources (first uplink resource and second uplink resource), allowing the terminal to transmit uplink data through multiple parallel paths. This segmentation enables the terminal to select alternative resources if one becomes unavailable, thereby reducing latency and improving reliability without significantly increasing overall system complexity.
Solution Approach 2:
The patent implements preliminary action by pre-configuring multiple uplink resources and establishing selection criteria before actual data transmission occurs. The terminal device is equipped with the capability to evaluate resource availability and select appropriate resources in advance, avoiding the need for re-scheduling and reducing communication latency when transmission opportunities arise.
2Productivity
If multiple uplink resources are allocated for uplink data transmission, then reliability and latency are improved, but device complexity increases
Solution Approach 1:
The patent applies dynamics by implementing flexible and adaptive resource selection mechanisms. The terminal device dynamically evaluates the availability and suitability of multiple pre-configured uplink resources based on current channel conditions and transmission requirements, selecting the most appropriate resource at the time of transmission. This dynamic approach allows the system to maintain high productivity while managing complexity through intelligent, condition-based resource allocation rather than rigid fixed assignments.
