Dynamic Measurement Gap Configuration for NR Signaling Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems face challenges in efficiently configuring measurement gaps for inter-frequency measurements in New Radio (NR) systems, particularly due to dynamic signal configurations and limited transmission occasions, which can lead to inefficient reconfiguration and reduced measurement performance.
Innovation Solution
A system and method that dynamically configure a measurement gap pattern with a limited duration for user equipment, allowing for efficient radio signal measurements by determining the gap pattern based on transmission configurations, numerology, and coverage levels, and enabling the selection of appropriate gap patterns to optimize measurement performance.

1Reliability
If measurement gap pattern is configured for extended duration to cover all transmission occasions, then measurement completeness is improved, but signaling overhead and resource waste increase
Solution Approach 1:
The measurement gap pattern is configured with a limited duration rather than being continuous or extended indefinitely. The duration is dynamically determined based on the actual transmission occasion parameters (periodicity, numerology, coverage level) to match the actual measurement needs, avoiding unnecessary extended gaps that would waste resources and increase signaling overhead.
Solution Approach 2:
The measurement gap duration parameter is adjusted based on specific transmission configuration parameters including periodicity, numerology (subcarrier spacing), and coverage level. By changing the duration parameter according to these conditions, the system achieves measurement completeness only for the necessary period while reducing unnecessary signaling overhead.
2Device complexity
If measurement gap pattern is configured with fixed duration, then configuration simplicity is improved, but adaptability to different transmission scenarios deteriorates
Solution Approach 1:
Instead of using a fixed measurement gap duration, the patent introduces parameter-based adaptation where the duration is determined by transmission occasion parameters (periodicity, numerology, coverage level). This allows the system to maintain relatively simple configuration procedures while achieving adaptability to different transmission scenarios through parameter adjustment.
Solution Approach 2:
The measurement gap configuration transitions from static/fixed to dynamic/adaptable by linking the duration to transmission occasion characteristics. The configuration remains relatively simple in structure but becomes adaptive in behavior, automatically adjusting to different scenarios such as different numerologies or coverage levels.
3Measurement precision
If measurement gap duration is extended to accommodate switching time, then measurement accuracy is improved, but available measurement time within gap is reduced
Solution Approach 1:
The measurement gap duration is precisely calibrated based on transmission parameters rather than using a fixed extended duration. This ensures the gap is long enough to accommodate necessary switching time for measurement accuracy, while not being excessively long to the point of reducing available measurement time within the gap.
