Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a user equipment simultaneously supports both 5G NR and E-UTRA radio access technologies, then the user can access both legacy and new network infrastructures, but the power consumption increases due to maintaining multiple radio resource monitoring tasks
Solution Approach 1:
The patent extracts and separates the monitoring tasks for different RATs into independent configurations. The network can configure separate monitoring occasions for E-UTRA and 5G NR, allowing the UE to selectively monitor only the necessary RATs at specific times, thereby reducing overall power consumption while maintaining multi-RAT access capability
Solution Approach 2:
The patent implements dynamic monitoring configurations where the UE can switch between monitoring E-UTRA and 5G NR based on configured schedules and network conditions. The monitoring behavior is made dynamic through time-domain configurations that enable the UE to activate or deactivate monitoring for specific RATs at different time intervals, optimizing power consumption adaptively
2Use of energy by moving object
If the network configures separate monitoring occasions for different RATs, then the power consumption is reduced, but the device complexity increases due to managing multiple monitoring configurations
Solution Approach 1:
The patent creates a universal monitoring configuration framework that handles multiple RATs through a unified configuration mechanism. The same configuration structure and procedures are used for both E-UTRA and 5G NR monitoring, allowing the UE to manage multiple RATs with a single set of rules and procedures, thereby reducing the perceived complexity despite supporting multiple monitoring occasions
3Productivity
If the monitoring occasions for E-UTRA and 5G NR overlap in time, then the UE can efficiently utilize resources, but the UE may miss detecting paging messages from one RAT when monitoring the other RAT
Solution Approach 1:
The patent segments the monitoring occasions for different RATs into distinct time intervals through configuration. By dividing the monitoring schedule into non-overlapping segments for E-UTRA and 5G NR, the UE can dedicate full attention to monitoring one RAT at a time, ensuring reliable paging message detection for each RAT without missing messages due to simultaneous monitoring conflicts
