Solution Overview

Problem

Existing communication systems face challenges in reducing data interruption time during reference signal measurements, particularly in scenarios where Network Controlled Small Gaps (NCSG) are not adequately supported or reported by terminal devices, leading to prolonged data transmission disruptions.

Innovation Solution

The terminal device sends first indication information to indicate its supported NCSG configuration, allowing the network device to adaptively configure measurements, thereby reducing data interruption time by utilizing NCSG, which requires only a short interruption for radio frequency chain adjustments.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If measurement gap is used for reference signal measurement, then measurement can be performed, but data transmission is interrupted

Engineering Contradiction:
Improvereference signal measurementVSAvoiddata transmission
Core Design Contradiction:
Measurement precisionVSProductivity

Solution Approach 1:

The patent applies dynamics by making the measurement gap configuration adaptive and reconfigurable. The network device dynamically adjusts measurement gap parameters based on terminal capabilities and measurement requirements, transitioning from static to dynamic gap configuration to minimize data transmission interruption while enabling reference signal measurement.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes measurement gap parameters (such as gap duration, periodicity, and offset) to optimize the balance between measurement accuracy and data transmission continuity. By adjusting these parameters based on terminal capabilities and network conditions, the system reduces interruption time while maintaining measurement precision.

Inventive Principle:
Principle #35Parameter changes

2Measurement precision

If measurement gap duration is extended to ensure measurement accuracy, then measurement precision improves, but data interruption time increases

Engineering Contradiction:
Improvemeasurement accuracyVSAvoiddata interruption time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent applies partial action by configuring measurement gaps that are sufficient but not excessive for measurement requirements. Instead of using fixed long-duration gaps, the system configures minimal necessary gap durations based on terminal capabilities and measurement needs, achieving adequate measurement accuracy with reduced data interruption.

Inventive Principle:
Principle #16Partial or excessive action

Solution Approach 2:

The system dynamically adjusts measurement gap duration based on real-time requirements, using shorter gaps when measurement accuracy is sufficiently achieved and extending only when necessary, thereby minimizing overall data interruption time while maintaining required measurement precision.

Inventive Principle:
Principle #15Dynamics

3Device complexity

If terminal device does not report NCSG capability, then configuration is simpler, but data interruption time cannot be reduced

Engineering Contradiction:
Improveconfiguration complexityVSAvoiddata interruption time
Core Design Contradiction:
Device complexityVSLoss of time

Solution Approach 1:

The patent introduces feedback by having terminal devices report their NCSG (Network Controlled Small Gap) capabilities to the network device. This capability feedback enables the network to configure appropriate small measurement gaps for terminals that support NCSG, reducing data interruption time while maintaining manageable configuration complexity through structured capability reporting.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent segments terminal devices into groups based on their NCSG capability support. Terminals are classified as NCSG-capable or non-capable, allowing the network to apply different measurement gap configurations to different segments, thereby reducing data interruption for capable terminals without complicating the overall configuration system.

Inventive Principle:
Principle #1Segmentation
