Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 3GPP networks do not provide guidance on how User Equipment (UE) should utilize measurement gaps configured for neighbor cell measurements, leading to potential inefficiencies in measurement performance and power consumption.

Adapting the measurement gap usage ratio based on factors such as serving cell quality, neighbor cell quality, and measurement fluctuation to optimize measurement performance while minimizing power consumption, by adjusting the scheduling rate of neighbor cell measurements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the UE performs neighbor cell measurements during all configured measurement gaps, then measurement performance is improved, but power consumption increases
Solution Approach 1:
The patent implements dynamic adaptation of measurement gap usage ratio based on serving cell quality measurements. When serving cell quality is high, the UE reduces measurement gap usage ratio to conserve power. When serving cell quality degrades, the UE increases measurement gap usage ratio to maintain measurement performance. This dynamic adjustment resolves the contradiction between maintaining measurement performance and reducing power consumption.
Solution Approach 2:
The patent changes the parameter of measurement gap usage ratio based on serving cell quality conditions. By adjusting this parameter according to channel conditions, the system optimizes the balance between measurement performance and power consumption, resolving the technical contradiction.
2Use of energy by moving object
If the UE reduces measurement gap usage to save power, then power consumption decreases, but measurement performance deteriorates
Solution Approach 1:
The patent implements a feedback mechanism where the UE continuously monitors serving cell quality and adjusts measurement gap usage ratio accordingly. This closed-loop control ensures that measurement performance is maintained at appropriate levels while optimizing power consumption, resolving the contradiction between these two parameters.
Solution Approach 2:
The system dynamically adjusts measurement behavior based on real-time channel conditions. When conditions are good, power consumption is reduced. When conditions deteriorate, measurement activity increases to maintain performance. This dynamic adaptation resolves the static contradiction between power consumption and measurement performance.
3Device complexity
If the network provides fixed measurement gap configuration, then configuration simplicity is maintained, but adaptability to varying channel conditions deteriorates
Solution Approach 1:
The patent enables the UE to autonomously adjust its measurement gap usage based on its own measurements of serving cell quality. This self-service approach allows the system to adapt to varying channel conditions without requiring complex network reconfiguration, resolving the contradiction between configuration simplicity and adaptability.
Solution Approach 2:
The system transitions from static fixed configuration to dynamic adaptive configuration. The measurement gap usage ratio is dynamically adjusted based on channel conditions while maintaining the simplicity of the initial network configuration. This resolves the contradiction between configuration simplicity and adaptability.
