Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the reference signal is configured by using one piece of single configuration signaling, then the configuration process is simple, but the flexibility is poor and cannot meet high accuracy requirements
Solution Approach 1:
The patent segments the reference signal configuration into multiple independent configuration sets (first measurement configuration set and second measurement configuration set), each containing different measurement parameters. This allows the base station to selectively activate different configuration sets based on channel conditions and service requirements, thereby improving configuration flexibility while maintaining operational simplicity through standardized set structures.
Solution Approach 2:
The patent implements dynamic configuration by allowing the base station to activate different measurement configuration sets at different times based on channel quality indicators and service requirements. The system transitions from static single-configuration to dynamic multi-configuration, enabling real-time adaptation to changing network conditions while maintaining a manageable configuration framework.
2Loss of energy
If the reference signal is configured only by using one piece of signaling, then the signaling overhead is low, but the measurement accuracy is insufficient for high accuracy requirements
Solution Approach 1:
The configuration is segmented into multiple measurement configuration sets, where each set contains specific measurement parameters (e.g., frequency domain resources, time domain resources, reference signal indices). Only the necessary configuration sets are activated and transmitted, reducing overall signaling overhead while providing sufficient measurement accuracy through selective configuration activation based on service requirements.
Solution Approach 2:
The patent changes the parameter structure by organizing measurement configurations into discrete, selectable sets with different parameter combinations. The base station can adjust which parameter sets are activated based on channel conditions and service types, achieving high measurement accuracy for specific scenarios without transmitting all possible configuration parameters, thus optimizing the balance between signaling overhead and measurement precision.
3Reliability
If redundant measurement results are reported, then the base station has sufficient information for channel estimation, but channel resources are wasted
Solution Approach 1:
The patent implements a feedback mechanism where the UE measures reference signals based on activated configuration sets and reports measurement results (such as channel quality indicators, precoding matrix indicators) back to the base station. The base station uses this feedback to dynamically adjust which measurement configuration sets remain activated, ensuring that sufficient channel estimation information is obtained while avoiding redundant measurements and reports, thus optimizing channel resource efficiency.
Solution Approach 2:
Instead of activating all possible measurement configuration sets, the system activates only the necessary subset based on current channel conditions and service requirements. This partial action approach ensures sufficient channel estimation information for reliable communication while avoiding the excessive action of activating and reporting all possible measurements, thereby eliminating channel resource waste.
4Device complexity
If the measurement configuration is fixed, then the system complexity is low, but it cannot adapt to changing channel parameters and communication modes
Solution Approach 1:
The measurement configuration is segmented into multiple independent configuration sets, each optimized for specific channel conditions or service types. The base station maintains a library of these pre-defined sets with manageable complexity, activating only the relevant sets based on current conditions. This segmentation allows the system to adapt to changing parameters without requiring a complete reconfiguration, maintaining low operational complexity while achieving high adaptability.
Solution Approach 2:
The system transitions from fixed configuration to dynamic configuration by enabling the base station to activate different measurement configuration sets based on real-time channel quality indicators, service requirements, and interference conditions. This dynamic approach allows the system to adapt to changing communication modes and channel parameters while maintaining a standardized configuration framework, balancing complexity and adaptability.
