Adaptive Measurement Gaps for Wireless Neighbor Cell Measurements
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, the inefficiency of resource utilization during measurement gaps for neighbor cell measurements leads to wasted time resources due to the inability to perform data transmission or reception during these gaps, especially in scenarios where neighbor cell measurement is not critical, such as low mobility conditions in XR services.
Innovation Solution
Adaptive measurement gap configuration methods and devices that allow flexible adjustment of measurement gaps, including partial slot activation, changing repetition periods, or canceling gaps to enable data transmission or reception during these times, triggered by network signaling or event-based conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the UE performs neighbor cell measurements during measurement gaps, then handover performance is improved, but resource utilization efficiency deteriorates due to inability to transmit or receive data during these gaps
Solution Approach 1:
The measurement gap configuration is made dynamic and adaptable rather than fixed. The network can trigger measurement gap indication to adapt the measurement gap configuration based on current conditions, allowing the system to flexibly adjust between measurement accuracy and resource utilization efficiency depending on mobility requirements
Solution Approach 2:
The patent changes the parameters of measurement gap configuration (such as gap duration, periodicity, or activation state) based on triggering conditions. By modifying these parameters dynamically, the system optimizes the balance between performing necessary measurements and maintaining data transmission efficiency
2Measurement precision
If the measurement gap is configured to ensure accurate neighbor cell measurement, then measurement precision is improved, but time resource loss increases due to longer or more frequent gaps
Solution Approach 1:
Instead of continuously configuring measurement gaps, the system applies partial action by triggering measurement gap indication only when necessary based on specific conditions. This ensures measurement precision is maintained when needed while minimizing time resource loss during periods when measurements are less critical
