Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If measurement consolidation thresholds are configured for RedCap UE with a single Rx chain, then measurement accuracy is improved, but device complexity increases

Engineering Contradiction:

Improvemeasurement accuracyVSAvoiddevice complexity

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The patent applies parameter changes by introducing a measurement consolidation threshold parameter that is specifically configured for RedCap UE with a single Rx chain. This parameter modifies the measurement evaluation process to consolidate measurements from multiple beams, thereby improving measurement accuracy without requiring additional hardware complexity. The threshold parameter enables the UE to select the best beam based on consolidated measurement results.

Inventive Principle:

Principle #35Parameter changes

2Measurement precision

If measurement consolidation is performed for RedCap UE, then measurement accuracy is improved, but processing time increases

Engineering Contradiction:

Improvemeasurement accuracyVSAvoidprocessing time

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The patent applies partial action by implementing measurement consolidation only when necessary and only for the extent required to improve accuracy. The consolidation threshold is applied selectively to beam measurements rather than all measurements, and the process stops once the threshold is satisfied, avoiding excessive processing time while achieving the required measurement accuracy improvement.

Inventive Principle:

Principle #16Partial or excessive action

3Reliability

If separate measurement thresholds are configured for single Rx chain UE, then measurement performance is improved, but system complexity increases

Engineering Contradiction:

Improvemeasurement performanceVSAvoidsystem complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies local quality by configuring separate measurement consolidation thresholds specifically for RedCap UE with a single Rx chain, while maintaining different thresholds for other UE types with multiple Rx chains. This localized differentiation ensures that each UE type receives optimized measurement parameters tailored to its specific capabilities, improving measurement performance without requiring a completely separate system architecture.

Inventive Principle:

Principle #3Local quality

AI summary

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a network node, a measurement configuration that indicates a measurement consolidation threshold. The UE may obtain a neighbor cell measurement based at least in part on a value of the measurement consolidation threshold for a UE having a single receive (Rx) chain. Numerous other aspects are described.
