Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

In wireless communication systems, RedCap UEs with narrower bandwidths face challenges in performing serving cell measurements due to the need for BWP switches and measurement gaps, leading to overhead and reduced throughput.

Innovation Solution

Configuring serving cell measurement objects (MOs) per bandwidth part (BWP) instead of per cell, allowing UEs to perform measurements without reconfiguration when switching BWPs, thereby avoiding measurement gaps and frequent RRC reconfigurations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If serving cell measurement objects are configured per cell (traditional approach), then measurement coverage is ensured, but signaling overhead increases and throughput decreases due to frequent reconfigurations and measurement gaps

Engineering Contradiction:

ImproveUE throughputVSAvoidsignaling overhead

Core Design Contradiction:

ProductivityVSLoss of information

Solution Approach 1:

The patent segments the serving cell measurement object configuration by associating it with specific bandwidth parts (BWPs) rather than configuring a single cell-wide measurement object. This allows the UE to use BWP-specific measurement objects when switching BWPs, eliminating the need for frequent RRC reconfigurations and reducing signaling overhead while maintaining measurement coverage.

Inventive Principle:

Principle #1Segmentation

2Adaptability or versatility

If BWP switches are performed frequently to adapt to different bandwidth requirements, then bandwidth adaptability is improved, but measurement continuity is disrupted due to required measurement gaps and reconfigurations

Engineering Contradiction:

Improvebandwidth adaptabilityVSAvoidmeasurement continuity

Core Design Contradiction:

Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The patent applies preliminary action by pre-configuring multiple BWP-specific serving cell measurement objects before BWP switching occurs. When a BWP switch is anticipated or performed, the UE already has the appropriate measurement object ready for the target BWP, eliminating the need for measurement gaps or post-switch reconfigurations, thus maintaining measurement continuity while preserving bandwidth adaptability.

Inventive Principle:

Principle #10Preliminary action

3Measurement precision

If measurement gaps are introduced to maintain measurement accuracy during BWP switches, then measurement precision is preserved, but time loss increases due to interrupted measurements

Engineering Contradiction:

Improveserving cell measurement accuracyVSAvoidmeasurement interruption time

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The patent enables continuity of useful action by ensuring that serving cell measurements can continue without interruption during BWP switches. Through BWP-specific measurement object configuration, the UE maintains measurement capability across BWP transitions, eliminating the need for measurement gaps and thus preserving both measurement precision and avoiding time loss.

Inventive Principle:

Principle #20Continuity of useful action
