Dynamic Measurement Gap Scheduling for Real-Time Data Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional communication technologies face service quality issues and data interruptions for real-time applications like virtual reality (VR) and augmented reality (AR) due to UE measurements during configured measurement gaps in LTE systems.
Innovation Solution
User equipment (UE) determines and reports an enabling or disabling condition for data scheduling within a configured time duration, allowing network nodes to adjust data transmission accordingly, ensuring uninterrupted service by considering serving cell quality and operation mode.

Engineering Contradiction Analysis
1Measurement precision
If the network node configures measurement gap for neighbor cell measurement, then the measurement accuracy is improved, but the data transmission for real-time application is interrupted
Solution Approach 1:
The network node determines in advance whether to configure measurement gaps based on UE assistance information indicating real-time application status. By proactively assessing the UE's application requirements before configuring measurement gaps, the system prevents service interruption for real-time applications while maintaining measurement capabilities when appropriate.
Solution Approach 2:
The measurement gap configuration becomes dynamic rather than static. The network node continuously receives UE assistance information and adjusts the measurement gap configuration accordingly - disabling measurement gaps when real-time applications are detected and enabling them when no real-time applications are running, thus adapting to changing service requirements.
2Reliability
If the network node disables measurement gap to maintain service continuity, then the service quality for real-time application is improved, but the neighbor cell measurement capability is degraded
Solution Approach 1:
The system dynamically switches between measurement gap enabled and disabled states based on real-time application status. When UE assistance information indicates real-time applications are running, measurement gaps are disabled to ensure service continuity. When no real-time applications are detected, measurement gaps are enabled to restore measurement capabilities.
Solution Approach 2:
The network node uses UE assistance information as feedback to continuously adjust measurement gap configuration. The UE reports its application status, and the network node responds by appropriately configuring or disabling measurement gaps, creating a closed-loop control system that balances measurement needs with service continuity.
3Productivity
If the network node schedules data during configured measurement gap, then the data transmission efficiency is improved, but the measurement accuracy is compromised
Solution Approach 1:
The patent extracts the measurement function from the measurement gap period by disabling measurement gaps entirely when real-time applications are detected. This eliminates the conflict between data transmission and measurement activities, allowing continuous data transmission without measurement interruptions while maintaining adequate measurement capability through alternative mechanisms.
Solution Approach 2:
The network node proactively disables measurement gaps before real-time application data transmission begins, based on UE assistance information. By preemptively removing the measurement gap configuration, the system ensures uninterrupted data transmission efficiency while measurement activities are suspended during the critical real-time application period.
Data Source
AI summary
Apparatus and method for data scheduling are proposed. The user equipment (UE) may provide an indication or a measurement report to the network node. The network node may determine whether to schedule data within at least one time duration which is configured to the UE for measurement based on the indication or the measurement report. Therefore, for some real-time application (e.g., virtual reality (VR) or augmented reality (AR)), the service will not be interrupted.
