Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple radio chains are allocated to different radio access technologies for parallel operation, then the capability to support multiple RATs is improved, but the device complexity and resource utilization increase
Solution Approach 1:
The patent merges multiple radio access technologies (5G NR and 6G NR) onto a single radio chain, allowing parallel operation of different RATs without requiring separate dedicated hardware chains for each technology. This consolidation reduces device complexity while maintaining multi-RAT support capability.
Solution Approach 2:
The radio chain is designed with multi-functionality to handle both 5G NR and 6G NR protocols simultaneously. The apparatus configures the same radio chain to operate with different RATs by adjusting configuration parameters, eliminating the need for specialized hardware for each technology.
2Reliability
If separate radio chains are used for different radio access technologies, then the reliability of each technology is improved, but the energy consumption increases
Solution Approach 1:
The patent combines 5G NR and 6G NR operations on a single radio chain, reducing the total number of active hardware components. This merging reduces energy consumption compared to maintaining separate dedicated radio chains for each RAT, while reliability is maintained through proper configuration management.
Solution Approach 2:
The system dynamically configures and reconfigures the radio chain based on periodic assessments of which RATs need to be active. This allows the radio chain to be efficiently allocated to different RATs only when needed, reducing energy consumption during idle periods for any particular technology.
3Productivity
If radio chains are shared between different radio access technologies, then the resource utilization is improved, but the difficulty of managing spectrum sharing increases
Solution Approach 1:
The apparatus implements feedback mechanisms that monitor the operational status, performance metrics, and configuration requirements of different RATs. This feedback enables the system to dynamically adjust radio chain allocation and resolve spectrum sharing conflicts, reducing the management difficulty while maintaining high resource utilization.
Solution Approach 2:
The patent introduces an intermediary configuration management apparatus that mediates between multiple RATs sharing a radio chain. This intermediary handles the complexity of spectrum sharing coordination, parameter adjustment, and conflict resolution, simplifying the overall management while enabling efficient resource utilization.
