Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If beam prediction procedures are implemented in existing wireless systems, then beam management capability is provided, but performance is suboptimal due to varying interference and user equipment mobility

Engineering Contradiction:

Improvebeam prediction performanceVSAvoidadaptability to interference and mobility

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The system performs preliminary actions by having the UE recommend reference signal resources before the beam prediction procedure is executed. The network entity selects auxiliary reference signals based on these recommendations in advance, preparing the beam prediction targets and resources beforehand to improve performance under varying conditions

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The UE provides feedback by recommending a set of reference signal resources for monitoring beam prediction performance. This feedback loop allows the network entity to adjust auxiliary reference signal selection based on UE observations of interference and mobility conditions, improving adaptability

Inventive Principle:

Principle #23Feedback

2Measurement precision

If reference signal resources are monitored for beam prediction performance, then beam prediction accuracy is improved, but resource overhead increases

Engineering Contradiction:

Improvebeam prediction accuracyVSAvoidreference signal resources

Core Design Contradiction:

Measurement precisionVSQuantity of substance

Solution Approach 1:

The system applies partial action by having the UE recommend a selective set of reference signal resources rather than monitoring all possible resources. The network entity transmits auxiliary reference signals only for selected beam prediction targets based on UE recommendations, achieving sufficient accuracy with reduced resource overhead

Inventive Principle:

Principle #16Partial or excessive action

Solution Approach 2:

The system changes parameters by allowing dynamic selection of reference signal resources based on UE recommendations. The network entity adjusts which auxiliary reference signals are transmitted based on the UE's recommended set, optimizing the balance between measurement precision and resource consumption

Inventive Principle:

Principle #35Parameter changes
