Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single programmable metasurface is shared among multiple network slices or management systems, then resource utilization efficiency is improved, but resource allocation complexity and interference management become more difficult
Solution Approach 1:
The patent applies segmentation by dividing a single physical programmable metasurface into multiple virtual programmable metasurfaces (vPMS), each independently managed and allocated to different network slices or tenants. The virtualization component creates logical partitions that appear as separate entities to management systems, enabling independent resource allocation while physically sharing the underlying hardware. This resolves the contradiction by maintaining high resource utilization through sharing while reducing allocation complexity through virtualization abstraction.
Solution Approach 2:
The patent introduces a metasurface virtualization component as an intermediary layer between the physical programmable metasurface and multiple management systems. This virtualization component manages resource allocation, isolation, and control, allowing multiple tenants to access the shared resource without direct interference. The intermediary handles the complexity of resource management internally while presenting simplified interfaces to external systems, thus improving utilization efficiency while containing allocation complexity within the virtualization layer.
2Productivity
If communication resources are shared through multiplexing, then resource utilization is improved, but signal interference and isolation requirements increase
Solution Approach 1:
The patent segments the communication resources of the shared metasurface into distinct virtual instances through virtualization. Each virtual programmable metasurface is associated with specific portions of communication resources (time slots, frequency ranges, phases) and is logically isolated from others. This segmentation enables multiplexing of resources while maintaining signal isolation through virtual boundaries, thus improving resource utilization without allowing harmful interference between different tenants' signals.
3Adaptability or versatility
If multiple virtual programmable metasurfaces are created from a single physical metasurface, then flexibility and adaptability are improved, but control and management complexity increase
Solution Approach 1:
The patent implements universality by designing a single physical programmable metasurface that can simultaneously serve multiple functions and tenants through virtualization. The metasurface is configured to support multiple virtual instances, each with its own communication functions, resource allocations, and management policies. This multi-functionality approach provides high flexibility and adaptability to different network slice requirements while the underlying physical infrastructure remains unified, reducing the need for multiple separate control systems.
Solution Approach 2:
The metasurface virtualization component acts as an intermediary that manages the complexity of controlling multiple virtual programmable metasurfaces. It provides a unified control interface that translates management system requests into coordinated control signals for the physical metasurface, handling resource allocation, isolation, and configuration internally. This intermediary approach enables high flexibility for multiple tenants while containing control complexity within the virtualization layer, preventing exponential growth in management complexity.
