Engineering Contradiction Analysis
1Productivity
If RIS operates in traditional separate reflection or sensing modes, then the system is simpler to implement, but the network performance and communication efficiency are limited
Solution Approach 1:
The patent combines reflection and sensing functions into a single hybrid mode of operation for the RIS. The RIS is configured to simultaneously perform reflection of reference signals and sensing of wireless communication parameters, merging two previously separate functions into one unified operation that improves network performance without proportionally increasing complexity
Solution Approach 2:
The RIS is designed to operate in multiple modes including hybrid sensing and reflection mode, making it a multi-functional device. This universality allows the same RIS infrastructure to serve both reflection purposes for signal routing and sensing purposes for wireless parameter measurement, eliminating the need for separate dedicated sensing devices
2Productivity
If RIS uses hybrid sensing and reflection mode with capability reports and resource configuration, then communication efficiency is improved, but the system complexity increases
Solution Approach 1:
The system performs preliminary configuration by establishing capability reports that define the RIS's sensing and reflection capabilities before actual operation. Resource configurations are pre-defined for reference signal measurements, allowing the RIS to efficiently execute hybrid mode operations without complex real-time decision-making, thus improving communication efficiency while managing complexity through advance planning
Solution Approach 2:
The system implements feedback mechanisms where the RIS reports its capabilities and measurement results back to the network. This feedback loop allows the network to optimize resource allocation and configuration based on actual RIS performance and wireless conditions, improving communication efficiency through adaptive optimization while keeping configuration complexity manageable through automated feedback-driven adjustments
