Concurrent Measurement Gaps for Faster Multi-Window Signal Measurement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile communication systems are limited by the configuration of a single measurement gap per period, leading to inefficient mobility handover due to the inability to cover multiple SMTC time windows or reference signals, resulting in prolonged measurement times.
Innovation Solution
Implementing a concurrent gap configuration that allows for multiple measurement gaps within a time period, enabling simultaneous measurement across different frequency ranges and reference signals, with specific configurations based on network scenarios and terminal capabilities.

Engineering Contradiction Analysis
1Productivity
If only one measurement gap is configured per period, then the device complexity is reduced and configuration is simpler, but the measurement efficiency deteriorates and measurement coverage is limited
Solution Approach 1:
The measurement gap configuration is segmented into multiple individual measurement gaps (first measurement gap, second measurement gap, etc.) that can be independently configured and activated. Each measurement gap can be associated with different reference signals or measurement objects, allowing the terminal to perform measurements on multiple frequency points or cells simultaneously or in sequence within a single period, thereby improving measurement efficiency without requiring a single excessively long gap.
Solution Approach 2:
The measurement gap configuration becomes dynamic through the introduction of activation and deactivation mechanisms. The network can selectively activate or deactivate specific measurement gaps based on current measurement needs, terminal capabilities, and network conditions. This dynamic control allows the system to adapt the measurement gap configuration in real-time, optimizing measurement efficiency while managing device complexity through flexible resource allocation.
2Adaptability or versatility
If the duration of measurement gap is extended to cover multiple measurement objects, then measurement coverage is improved, but the throughput loss increases due to longer interruption time
Solution Approach 1:
Instead of using one long measurement gap to cover multiple measurement objects, the configuration is segmented into multiple shorter measurement gaps distributed within the period. Each measurement gap can be dedicated to specific measurement objects or reference signals. This segmentation allows the terminal to perform measurements more efficiently with shorter interruptions, reducing throughput loss while maintaining comprehensive measurement coverage across multiple frequency points or cells.
Solution Approach 2:
Measurement gaps are configured to occur periodically with multiple instances within a single period. Each periodic measurement gap opportunity can be used for different measurement objects. This periodic structure allows the terminal to distribute measurement activities across multiple time points rather than concentrating them in one long gap, thereby maintaining measurement coverage while minimizing continuous interruption to data transmission and reducing overall throughput loss.
