Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple transmission antenna panels are employed to enhance reliability and robustness, then transmission reliability is improved, but device complexity increases
Solution Approach 1:
The system segments transmission functions across multiple antenna panels, where each panel can independently transmit signals. This segmentation allows the system to achieve diversity gain and improve reliability by distributing transmission across multiple physical entities, while the modular nature of segmentation keeps each panel's complexity manageable.
Solution Approach 2:
The antenna panels are designed with multi-functionality, capable of serving both uplink and downlink transmissions, and supporting both data and control channels. This universal design reduces overall system complexity by using the same hardware resources for multiple purposes rather than requiring dedicated components for each function.
2Adaptability or versatility
If antenna-panel switching is implemented to support multiple transmission schemes, then adaptability is improved, but time delay increases
Solution Approach 1:
The system performs preliminary configuration of antenna panel states and transmission parameters before actual data transmission begins. By pre-configuring the antenna panels and having switching decisions prepared in advance based on channel conditions, the system minimizes the actual switching time during active transmission, thus reducing time loss while maintaining adaptability.
Solution Approach 2:
The antenna panel selection and switching are made dynamic based on real-time channel conditions and transmission requirements. The system can adaptively switch between different antenna panels and transmission schemes without fixed predetermined patterns, optimizing the balance between adaptability and switching time loss according to current operational needs.
3Productivity
If dynamic scheduling of multiple transmission schemes is implemented, then productivity is improved, but device complexity increases
Solution Approach 1:
The dynamic scheduling system operates with periodic updates and evaluations of transmission schemes. By using periodic scheduling intervals and structured decision-making cycles, the system achieves efficient resource utilization through regular optimization opportunities, while the periodic nature provides a manageable framework that reduces scheduling complexity compared to completely continuous or ad-hoc scheduling approaches.
