Dynamic Measurement Gap Adaptation for XR Service Continuity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In LTE systems, measurement gaps configured for neighbor cell measurements can disrupt real-time applications like extended reality (XR), leading to service quality issues and user experience problems.
Innovation Solution
A method where a network node dynamically adapts the measurement gap configuration by transmitting DCI or MAC-CE to a UE, indicating adaptations such as activating, deactivating, or changing the settings of measurement gaps, based on the type of traffic associated with the UE.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If measurement gaps are configured for neighbor cell measurement, then measurement precision is improved, but data service continuity deteriorates
Solution Approach 1:
The patent applies dynamics by making the measurement gap configuration adjustable and adaptable rather than fixed. The network node can dynamically modify measurement gap parameters (such as gap length, gap offset, or gap pattern) based on real-time traffic conditions and UE requirements, allowing the system to balance between measurement precision and data service continuity flexibly
Solution Approach 2:
The patent changes measurement gap parameters dynamically based on traffic type identification. For real-time traffic (e.g., VR/AR), the system can reduce measurement gap frequency or extend gap duration to minimize data interruption. For non-real-time traffic, standard measurement gaps are maintained. This parameter adaptation resolves the contradiction by optimizing measurement precision for each traffic scenario
2Measurement precision
If measurement gaps are configured for neighbor cell measurement, then measurement precision is improved, but service quality deteriorates
Solution Approach 1:
The patent implements feedback mechanisms where the network node monitors traffic characteristics and UE performance metrics, then adjusts measurement gap configuration accordingly. The system can detect when measurement gaps cause service quality degradation and automatically modify gap parameters to maintain reliable service while preserving measurement capabilities
Solution Approach 2:
The patent applies local quality by tailoring measurement gap configurations to specific UE requirements and traffic types rather than applying a uniform approach. Each UE can have customized measurement gap settings based on its service requirements, allowing high service quality for real-time applications while maintaining measurement precision where needed
3Measurement precision
If measurement gaps are configured for neighbor cell measurement, then measurement precision is improved, but user experience deteriorates
Solution Approach 1:
The patent enables self-service by having the system automatically identify traffic types and adjust measurement gaps without requiring manual user configuration. The network node autonomously monitors service quality metrics and user experience indicators, then adapts measurement gap settings to maintain optimal performance, making the system responsive to user needs without user intervention

AI summary
Various solutions for adaptation of measurement gap configuration with dynamic control signaling are described. A network node may transmit a configuration of one or more measurement gaps (MGs) to a user equipment (UE). The network node may determine a specific type of traffic associated with the UE. The network node may transmit a downlink control information (DCI) or a medium access control-control element (MAC-CE) to the UE. The DCI or the MAC-CE may indicate an adaptation of at least one of the one or more MGs.
