Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, measurement gaps conflict with XR services, leading to potential interruptions due to non-integral transmission periods and high latency requirements, especially in XR services like VR and AR, which are severely impacted by delays or errors.
Innovation Solution
A method for configuring measurement gaps in wireless communications, where frequencies are set as a frequency set, and measurement gaps are determined to be orthogonal and non-consecutive, allowing for flexible configuration to avoid conflicts with XR traffic and ensure uninterrupted service.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If measurement gaps are configured for inter-frequency and inter-RAT network measurements, then measurement capability is improved, but traffic interruption increases and service quality deteriorates
Solution Approach 1:
The patent segments the measurement gap configuration into multiple independent measurement gap sets, each associated with specific frequency sets. This allows selective activation of measurement gaps only when needed for specific inter-frequency or inter-RAT measurements, rather than continuously interrupting traffic. The segmentation enables the system to balance measurement requirements with service continuity by activating measurement gaps only in specific time windows.
Solution Approach 2:
The patent introduces dynamic configuration of measurement gaps where the network can flexibly adjust measurement gap settings based on current traffic conditions and measurement needs. The system dynamically determines when measurement gaps should be activated or deactivated, allowing adaptive management of the contradiction between measurement capability and service continuity. This dynamic approach enables real-time optimization of service quality while maintaining measurement functionality.
2Ease of manufacture
If measurement gaps are configured with fixed periods, then measurement scheduling is simplified, but conflict with XR services occurs causing interruptions
Solution Approach 1:
The patent transforms fixed measurement gap periods into dynamic, flexible time window configurations. Instead of rigid fixed schedules, the system uses configurable time windows that can be adjusted to avoid conflicts with XR services. This dynamic approach maintains scheduling simplicity while eliminating the harmful conflicts that cause interruptions during critical XR transmission periods.
Solution Approach 2:
The patent changes the parameter of measurement gap timing from fixed periodic intervals to flexible time window configurations. By allowing variable timing parameters and adjustable time windows, the system can adapt measurement gap scheduling to avoid conflicts with XR services. This parameter change enables the system to maintain measurement functionality while preserving service quality during critical transmission periods.
3Measurement precision
If measurement gaps are extended to accommodate switching transition time, then measurement completeness is improved, but traffic interruption increases
Solution Approach 1:
The patent segments the measurement process into discrete measurement gaps that are strategically positioned to accommodate switching transition times without extending overall interruption duration. By dividing the measurement requirement into separate, manageable gaps rather than one extended continuous gap, the system achieves measurement completeness while minimizing total time loss and maintaining service continuity.
