Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If OAM resources are allocated for measuring OAM states, then communication capacity and reliability are enhanced, but device complexity and resource management difficulty increase
Solution Approach 1:
The patent implements dynamic allocation and activation/deactivation of OAM resources based on communication conditions. The base station can dynamically activate or deactivate OAM state measurement functions and allocate OAM resources as needed, rather than maintaining fixed configurations. This dynamic approach allows the system to adapt to changing communication requirements, enhancing reliability when OAM measurement is beneficial while reducing complexity when it is not required.
Solution Approach 2:
The patent changes the operational parameters of OAM resources by introducing activation and deactivation states. Through control signaling, the system can modify the parameter states of OAM resources (active/inactive), allowing flexible adjustment of resource allocation. This parameter-based control enables the system to optimize between reliability enhancement and complexity reduction by adjusting resource states based on communication needs.
2Productivity
If OAM resources are dynamically activated and deactivated, then resource utilization efficiency improves, but control signaling overhead increases
Solution Approach 1:
The patent implements periodic allocation patterns for OAM resources, where resources are activated and deactivated in periodic cycles based on communication patterns. This periodic approach allows the system to efficiently utilize OAM resources during active periods while minimizing control signaling overhead during inactive periods. The periodic nature creates predictable resource availability that balances utilization efficiency with signaling overhead.
3Adaptability or versatility
If multiple allocation methods (periodic, semi-persistent, aperiodic) are supported, then adaptability to different communication scenarios improves, but system complexity increases
Solution Approach 1:
The patent implements a universal resource allocation framework that supports multiple allocation methods (periodic, semi-persistent, and aperiodic) through a common control structure. The base station can select different allocation methods based on communication scenario requirements, allowing the same system infrastructure to serve multiple functions. This multi-functional approach enhances adaptability while managing complexity through unified resource management principles that apply across all allocation types.
