Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If the measurement type adopted by the terminal is updated, then the measurement precision can be improved, but the base station cannot determine the accurate measurement parameters in time

Engineering Contradiction:
Improvemeasurement parameter accuracyVSAvoidresponse time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The base station pre-calculates and stores multiple sets of measurement parameters corresponding to different measurement types (e.g., different CSI feedback modes, different codebook configurations) before the terminal needs to switch. When the terminal indicates a measurement type update, the base station can immediately retrieve the pre-prepared parameters without calculation delay, thus maintaining both accuracy and timeliness.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system implements dynamic parameter adaptation where the base station maintains a library of measurement parameters that can be quickly switched based on terminal feedback. The measurement parameters are made dynamic and configurable rather than fixed, allowing the base station to adapt to different measurement types in real-time based on terminal capabilities and channel conditions.

Inventive Principle:
Principle #15Dynamics

2Productivity

If multi-antenna technology is used to improve system performance, then the productivity increases, but the complexity of determining accurate measurement parameters increases

Engineering Contradiction:
Improvewireless communication system performanceVSAvoidmeasurement parameter determination complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The measurement parameter determination process is segmented into multiple independent components: terminal capability reporting, measurement type indication, parameter selection, and parameter application. Each component handles a specific aspect of the overall process, making the complex multi-antenna measurement parameter determination manageable and systematic rather than monolithic.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system implements a feedback mechanism where the terminal reports its measurement capabilities and selected measurement types back to the base station. The base station uses this feedback to automatically select and configure the appropriate measurement parameters from its library, reducing the complexity of manual configuration and ensuring optimal parameters are used for the specific multi-antenna scenario.

Inventive Principle:
Principle #23Feedback
