Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the network node transmits connection configurations frequently to switch between different configurations, then the network can adapt to changing conditions, but the signaling overhead and resource utilization deteriorate
Solution Approach 1:
The network node stores multiple connection configurations in advance and transmits only the necessary configuration information (such as configuration indices or identifiers) rather than complete configurations. This preliminary preparation allows the system to switch between configurations efficiently without repeatedly transmitting full configuration data, thereby reducing signaling overhead while maintaining adaptability.
Solution Approach 2:
The patent extracts only the essential configuration parameters needed for switching between connection configurations. Instead of transmitting complete configurations, the system extracts and transmits only the necessary identifiers or indices that reference pre-stored configurations, significantly reducing the quantity of signaling data while preserving the ability to switch between different network conditions.
2Adaptability or versatility
If the network node transmits additional connection configurations to enable switching, then the adaptability improves, but the use of energy and network resources deteriorates
Solution Approach 1:
Connection configurations are pre-stored at the network node before actual switching is needed. When a configuration switch is required, the system retrieves the appropriate pre-stored configuration rather than transmitting a complete new configuration, thereby reducing energy consumption associated with configuration transmissions while maintaining the ability to adapt to changing network conditions.
Solution Approach 2:
The system extracts and transmits only the minimal necessary information (such as configuration indices) required for switching, rather than transmitting complete configuration datasets. This extraction approach significantly reduces the energy consumption for configuration transmissions while preserving the network's adaptability to different operational conditions.
3Extent of automation
If the UE stores multiple connection configurations locally, then the autonomous switching capability improves, but the device complexity increases
Solution Approach 1:
The network node creates simplified references or copies of connection configurations (such as configuration indices or pointers) that the UE can store and manage. These references point to the actual full configurations stored in the network node, allowing the UE to perform autonomous switching using lightweight identifiers rather than storing complete configuration datasets, thereby reducing device complexity while enabling automation.
Solution Approach 2:
The patent introduces configuration identifiers or indices as intermediary elements between the UE and full connection configurations. The UE stores and manages these lightweight intermediaries locally, while the network node maintains the complete configuration data. This intermediary layer enables autonomous switching at the UE level without requiring the UE to store or process complete configurations, thus reducing device complexity.

AI summary
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may communicate in a network based at least in part on using a first connection configuration. The UE may communicate in the network based at least in part using a second connection configuration instead of the first connection configuration. The UE may autonomously switch to reusing the first connection configuration for communicating in the network based at least in part on the first connection configuration being stored at the UE. Numerous other aspects are described.
