Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional wireless communication frame structures are used, then simplicity of implementation is maintained, but spectrum utilization efficiency across multiple operators deteriorates
Solution Approach 1:
The frame structure is segmented into distinct acquisition intervals and transmission opportunities for different operators. Each operator has dedicated acquisition intervals and guaranteed transmission opportunities, preventing overlap and ensuring efficient spectrum utilization across multiple operators without causing interference.
Solution Approach 2:
The frame structure incorporates dynamic elements where transmission opportunities can be adjusted based on operator priorities and spectrum conditions. The guaranteed transmission opportunities allow operators to dynamically access spectrum resources based on their service requirements, optimizing overall spectrum efficiency.
2Productivity
If multiple operators share spectrum resources, then spectrum utilization improves, but transmission reliability and priority guarantee deteriorate
Solution Approach 1:
The shared spectrum is segmented into dedicated acquisition intervals and guaranteed transmission opportunities for each operator. This segmentation ensures that each operator has guaranteed access to specific time slots, maintaining transmission reliability while enabling multiple operators to share the spectrum efficiently.
Solution Approach 2:
The frame structure acts as an intermediary mechanism that coordinates between multiple operators. It provides a structured framework where acquisition intervals and transmission opportunities are allocated to different operators, ensuring reliable transmission while maximizing spectrum utilization through coordinated access.
3Reliability
If transmission opportunities are guaranteed for each operator, then transmission reliability improves, but time efficiency and access speed deteriorate
Solution Approach 1:
The frame structure implements periodic acquisition intervals and transmission opportunities for each operator. This periodic allocation ensures reliable transmission guarantees while optimizing time efficiency by allowing operators to access spectrum resources at regular intervals without unnecessary delays or waiting periods.
Solution Approach 2:
Acquisition intervals are performed in advance of transmission opportunities, allowing operators to prepare for and secure their transmission slots beforehand. This preliminary action ensures that when transmission time arrives, operators can immediately begin transmitting without delays, reducing overall access time while maintaining reliability.
