Measurement Gap Configuration Per Frequency Group and Cell
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cellular network technologies face challenges in configuring measurement gaps effectively, particularly in fifth-generation (5G) networks, where high-frequency carriers require efficient resource utilization and synchronization signal burst configurations to support intrafrequency/interfrequency measurements for handover and beam management.
Innovation Solution
The solution involves configuring measurement gaps per frequency group and cell, allowing for flexible allocation of time and frequency resources for synchronization signal bursts, enabling user equipment (UE) to perform measurements during designated gaps, and signaling UE preferences based on carrier aggregation configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If measurement gaps are configured for high-frequency carriers to enable intrafrequency/interfrequency measurements, then measurement capability is improved, but resource utilization and scheduling efficiency deteriorate due to interruptions
Solution Approach 1:
The patent segments the frequency spectrum into multiple frequency groups, each with independent measurement gap configurations. This allows measurement gaps to be applied selectively to specific frequency groups rather than globally, enabling measurements on high-frequency carriers while maintaining continuous operation on other carriers, thus resolving the contradiction between measurement capability and resource utilization
Solution Approach 2:
The patent introduces dynamic measurement gap configuration where the network can flexibly adjust measurement gap patterns based on carrier aggregation configurations and UE capabilities. The measurement gap configuration can be modified in real-time to balance measurement requirements against resource utilization efficiency, transforming a static contradiction into a dynamically manageable situation
2Reliability
If measurement gaps are configured per cell to support handover and beam management, then mobility management is improved, but system complexity increases due to per-cell configuration management
Solution Approach 1:
The patent creates a universal measurement gap configuration framework that can be applied across multiple cells and frequency groups. Instead of managing completely independent per-cell configurations, the system uses a unified configuration mechanism that can be selectively applied to different cells based on their specific needs, reducing overall system complexity while maintaining the ability to support handover and beam management
Solution Approach 2:
The patent applies local quality by allowing different measurement gap configurations for different frequency groups and cells based on their specific requirements. High-frequency carriers that need frequent measurements can have more aggressive gap configurations, while other carriers use standard configurations, optimizing both reliability and complexity management through localized customization

AI summary
Systems, methods, and apparatuses may configure a measurement gap per frequency group and per cell. Measurement time and frequency resources may be associated with a carrier frequency, a cell, or both. Thus, a user equipment (UE) may determine the measurement configuration based on the carrier frequency, cell, or both. The number of synchronization sequences (SS) blocks in an SS burst may be based on the frequency band of the carrier frequency.
