Dynamic Measurement Gaps for Low-Latency Positioning Measurement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wireless communication systems face increased processing latency due to fixed and repetitive measurement gaps, which hinder accurate and timely location-based services by limiting the flexibility and efficiency of positioning measurements.
Innovation Solution
Implementing dynamic measurement gaps through a capability report, processing indicator, and gap request to coordinate aperiodic or on-demand measurement gaps, allowing terminal devices to dynamically schedule and measure positioning reference signals without fixed intervals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If fixed and repetitive measurement gaps are used, then measurement scheduling is simplified, but processing latency increases and measurement flexibility is reduced
Solution Approach 1:
The patent implements dynamic measurement gap configuration where the network device can activate or deactivate measurement gaps based on real-time positioning requirements. Instead of fixed periodic gaps, the system uses MAC CE commands to dynamically control measurement gap timing and duration, allowing the terminal to perform measurements only when needed, thus reducing unnecessary waiting time and processing latency while maintaining scheduling simplicity through centralized control.
2Ease of operation
If fixed measurement gaps are used, then system operation is simpler, but positioning accuracy and granularity are reduced
Solution Approach 1:
The patent employs periodic measurement gaps with configurable periods and durations that can be dynamically adjusted. The network device configures multiple measurement gap patterns with different periodicities (e.g., 40ms, 80ms, 160ms) and allows switching between them based on positioning accuracy requirements. This periodic structure maintains operational simplicity through standardized patterns while enabling high measurement precision by selecting appropriate periods and activating multiple patterns simultaneously for fine-grained positioning.
