Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional communication protocols and control methods are applied to RIS, then the control process is simple, but the network performance and coverage are suboptimal
Solution Approach 1:
The patent introduces a dedicated RIS-RNTI as an intermediary identifier that mediates between traditional communication protocols and RIS-specific control requirements. This intermediary enables the base station to specifically identify and control RIS equipment through dedicated signaling, resolving the contradiction by adding a targeted control layer without completely overhauling the existing protocol framework
Solution Approach 2:
The patent changes the identification parameter from generic communication identifiers to a dedicated RIS-RNTI parameter. This parameter change allows the system to distinguish RIS equipment from other network elements, enabling optimized control strategies that improve network performance while maintaining protocol compatibility
2Measurement precision
If dedicated RIS-RNTI scrambling code is used to identify RIS equipment, then the control precision is improved, but the signaling overhead increases
Solution Approach 1:
The RIS-RNTI scrambling code serves multiple functions simultaneously: it identifies RIS equipment, enables dedicated control signaling, and maintains compatibility with existing protocol structures. This multi-functionality reduces the need for separate identification mechanisms, thereby limiting the increase in signaling overhead while achieving precise identification
3Area of stationary object
If traditional control methods are used, then the device complexity is low, but the signal coverage is insufficient
Solution Approach 1:
The patent segments the control process into distinct phases: identification phase using RIS-RNTI, regulation phase for operating modes, and coordination phase for phase states. This segmentation allows traditional low-complexity infrastructure to be enhanced with targeted RIS control capabilities, improving signal coverage without requiring complete system redesign
4Productivity
If RIS equipment is not accurately identified, then the control signaling is simple, but the cell multiplexing capacity is reduced
Solution Approach 1:
The RIS-RNTI acts as an intermediary that enables the base station to specifically target RIS equipment in control signaling. This intermediary mechanism allows for precise identification without requiring complex address resolution protocols, thereby enhancing cell multiplexing capacity through efficient resource allocation and interference management
