Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing wireless communication systems face inefficiencies in activating and deactivating measurement gaps, leading to wasted network resources and increased UE power consumption due to improper synchronization signal block (SSB) measurements, particularly with Layer 3 intra-frequency measurements using non-cell-defining SSBs within active downlink bandwidth-parts (BWPs).

Innovation Solution

A UE or network node configures conditions for deactivating measurement gaps based on SSB or CSI-RS intra-frequency measurements fully contained within the active downlink BWP and the presence of a serving cell measurement object indicator in the BWP dedicated information element, allowing autonomous gap deactivation without additional signaling.

VSEngineering Contradiction Analysis

1Measurement precision

If measurement gap is activated to perform SSB measurements, then measurement accuracy is improved, but network resource efficiency deteriorates and UE power consumption increases

Engineering Contradiction:

ImproveSSB measurement accuracyVSAvoidUE power consumption

Core Design Contradiction:

Measurement precisionVSLoss of energy

Solution Approach 1:

The patent implements dynamic measurement gap activation and deactivation based on real-time measurement needs. The UE autonomously activates measurement gaps when SSB measurements are required and deactivates them when measurements can be performed within the active BWP, optimizing the balance between measurement accuracy and power consumption.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent changes the operational parameters of measurement gaps by introducing conditions for their activation and deactivation. Specifically, it modifies the measurement object indicator parameters and BWP configuration parameters to determine whether measurement gaps are needed, thereby reducing unnecessary power consumption while maintaining measurement accuracy.

Inventive Principle:

Principle #35Parameter changes

2Measurement precision

If measurement gap is activated to perform SSB measurements, then measurement accuracy is improved, but network resource efficiency deteriorates

Engineering Contradiction:

ImproveSSB measurement accuracyVSAvoidnetwork resource efficiency

Core Design Contradiction:

Measurement precisionVSProductivity

Solution Approach 1:

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent enables continuous useful action by allowing SSB measurements to be performed continuously within the active BWP without requiring periodic measurement gap activation. This maintains measurement capability while eliminating the interruptions and resource waste associated with traditional measurement gap approaches.

Inventive Principle:

Principle #20Continuity of useful action

3Use of energy by moving object

If measurement gap is deactivated for intra-frequency measurements, then power consumption is reduced, but measurement capability may deteriorate

Engineering Contradiction:

ImproveUE power consumptionVSAvoidmeasurement capability

Core Design Contradiction:

Use of energy by moving objectVSReliability

Solution Approach 1:

The patent applies local quality by making measurement capabilities available specifically within the active BWP region where SSB signals are present. Instead of requiring global measurement gap activation, the UE can perform measurements locally within the active BWP, reducing power consumption while maintaining measurement reliability for intra-frequency cells.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The patent enables the UE to self-determine when measurement gaps are needed based on its own measurement requirements and BWP configuration. The UE autonomously activates or deactivates measurement gaps without network signaling, allowing it to self-optimize between power consumption and measurement capability based on real-time conditions.

Inventive Principle:

Principle #25Self-service
