Measurement Gap Skipping for Low-Latency Cell Search
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices face high power consumption and latency issues during inter-frequency and inter-radio access technology mobility procedures due to excessive use of measurement gaps for signal search and measurement, leading to inefficient power usage and inaccurate results.
Innovation Solution
Implementing a method to determine whether the measured gain state matches an appointed gain state and detect new cells, allowing the device to skip subsequent measurement gaps when conditions are met, thereby reducing unnecessary power consumption and latency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If measurement gaps are used for signal search and measurement during inter-frequency and inter-RAT mobility procedures, then measurement accuracy is improved, but power consumption increases
Solution Approach 1:
The patent applies partial action by performing measurement gap skipping - instead of executing all scheduled measurement gaps, the device selectively skips subsequent measurement gaps when the measured gain state matches the appointed gain state and no new cell is detected. This partial execution of measurement operations reduces power consumption while maintaining sufficient measurement accuracy for mobility procedures.
Solution Approach 2:
The patent changes the operational parameters of measurement gaps by introducing conditional skipping logic based on gain state matching and cell detection results. When conditions are met (measured gain state equals appointed gain state and no new cell detected), the measurement gap parameter is changed from 'execute' to 'skip', thereby reducing power consumption while maintaining measurement capability when needed.
2Measurement precision
If measurement gaps are used for signal search and measurement during inter-frequency and inter-RAT mobility procedures, then measurement coverage is improved, but latency increases
Solution Approach 1:
The patent applies partial action by skipping unnecessary subsequent measurement gaps when measurement conditions are already satisfied. By selectively executing only the necessary measurement gaps (skipping redundant ones), the device reduces the total time spent on measurement procedures, thereby reducing latency while maintaining adequate measurement coverage for mobility decisions.
Solution Approach 2:
The patent directly applies the skipping principle by allowing the device to rush through redundant measurement gaps when the measured gain state matches the appointed gain state and no new cell is detected. This skipping mechanism eliminates unnecessary waiting time and measurement cycles, directly reducing latency in inter-frequency and inter-RAT mobility procedures while preserving measurement coverage through selective execution.
3Reliability
If multiple measurement gaps are scheduled for gain state verification and cell detection, then measurement reliability is improved, but device complexity increases
Solution Approach 1:
The patent applies partial action by implementing conditional skipping of subsequent measurement gaps based on outcomes from the first measurement gap. Instead of uniformly executing all scheduled measurement gaps, the device performs partial execution - skipping redundant gaps when conditions are met (gain state matches and no new cell detected). This maintains measurement reliability through selective verification while reducing the overall complexity of measurement gap management.
