Engineering Contradiction Analysis
1Reliability
If reconfigurable intelligent surfaces (RISs) are deployed to improve signal propagation and reduce path loss, then communication quality is improved, but device complexity and configuration difficulty increase
Solution Approach 1:
The RIS controller autonomously performs discovery beacon transmission, configuration information reception, and RIS element configuration without requiring manual intervention. The system self-configures by processing discovery beacons from neighboring base stations, selecting optimal configurations, and applying them to RIS elements, thereby improving communication quality while managing complexity through automation
Solution Approach 2:
The configuration process incorporates feedback mechanisms where the RIS controller receives configuration information from base stations, evaluates signal conditions, and adjusts RIS element configurations accordingly. This feedback loop enables the system to adapt to changing channel conditions and optimize performance while managing configuration complexity through iterative refinement
2Productivity
If multiple RIS configurations are implemented to optimize signal paths, then signal strength and throughput increase, but system complexity and control difficulty increase
Solution Approach 1:
The system implements dynamic RIS configuration where the controller can switch between multiple pre-configured RIS configurations based on real-time signal conditions. The configuration information includes multiple RIS configuration options that can be dynamically selected and applied to optimize signal paths for different user equipment and channel conditions, enabling throughput improvement while managing control complexity through dynamic adaptation
Solution Approach 2:
Multiple RIS configurations are pre-computed and stored in the configuration information before being applied. The RIS controller receives and stores multiple RIS configuration options in advance, allowing it to quickly switch between pre-optimized configurations rather than computing them in real-time, thereby improving throughput while reducing the computational complexity of real-time control
