Engineering Contradiction Analysis
1Reliability
If configuration information is provided without specifying configuration mode, then terminal device can obtain cell or cell group configuration, but consistent understanding of configuration behavior cannot be ensured between terminal device and network-side device
Solution Approach 1:
The network-side device performs preliminary action by determining and indicating the configuration mode (full configuration or delta configuration) before providing configuration information to the terminal device. This ensures the terminal device understands how to process the configuration information correctly, maintaining consistent configuration behavior between both devices.
Solution Approach 2:
The configuration mode indication serves as a feedback mechanism that guides the terminal device's configuration processing behavior. By providing explicit mode information, the network-side device enables the terminal device to adjust its configuration application accordingly, ensuring reliable and consistent configuration understanding.
2Reliability
If configuration mode is always specified explicitly, then configuration behavior consistency is ensured, but signaling overhead increases
Solution Approach 1:
The patent applies local quality by specifying configuration mode indication only where necessary - i.e., when providing configuration information that requires specific processing behavior. This selective approach ensures configuration consistency is maintained only when needed, rather than universally applying mode indications in all configuration scenarios, thereby reducing unnecessary signaling overhead.
3Quantity of substance
If delta configuration mode is used without reference configuration information, then configuration signaling is reduced, but terminal device cannot correctly apply configuration
Solution Approach 1:
When using delta configuration mode, the network-side device performs preliminary action by providing reference configuration information before the terminal device applies the delta configuration. This reference configuration serves as the baseline that the terminal device needs to correctly interpret and apply the delta updates, ensuring configuration application accuracy while still benefiting from reduced signaling compared to full configuration.
Solution Approach 2:
The reference configuration information acts as an intermediary that bridges the gap between reduced delta configuration signaling and accurate configuration application. It provides the necessary context that enables the terminal device to correctly apply delta updates without requiring complete configuration information to be transmitted.
