Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in efficiently managing measurement gaps and resource allocation for User Equipment (UE) in dual connectivity scenarios, particularly in 5G networks, which affects data transmission reliability and power consumption.
Innovation Solution
The method involves a UE receiving measurement gap configuration information from a base station, which includes the frequency range for measurement gaps, allowing the UE to perform specific operations during these gaps, such as stopping PUCCH transmission and PDCCH monitoring, to optimize resource usage and reduce power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If measurement gap configuration is applied in dual connectivity scenarios, then measurement accuracy is improved, but device complexity and power consumption increase
Solution Approach 1:
The patent segments the measurement gap configuration by applying different measurement gap patterns to different cell groups (MCG and SCG) independently. This allows the UE to perform measurements on specific frequency ranges during designated gaps without requiring a single comprehensive measurement gap configuration, thereby reducing overall device complexity while maintaining measurement accuracy.
Solution Approach 2:
The patent implements dynamic measurement gap configuration where the base station can adjust measurement gap patterns, durations, and frequency ranges based on current network conditions and UE capabilities. This dynamic approach allows the system to optimize measurement accuracy only when needed while reducing measurement activities and associated complexity during stable conditions.
2Adaptability or versatility
If multiple measurement gaps are configured for different frequency ranges, then measurement coverage is improved, but power consumption increases
Solution Approach 1:
The patent applies partial action by configuring measurement gaps only for specific frequency ranges and cell groups that require measurement, rather than applying measurement gaps universally across all frequencies and cell groups. This selective approach ensures comprehensive measurement coverage where needed while minimizing unnecessary measurement activities that would increase power consumption.
Solution Approach 2:
The patent implements periodic measurement gap patterns where measurements are performed at regular intervals rather than continuously. This periodic approach allows the UE to maintain measurement coverage by periodically sampling different frequency ranges while significantly reducing overall power consumption compared to continuous measurement across all frequencies.
3Productivity
If PUCCH transmission and PDCCH monitoring are stopped during measurement gaps, then resource allocation efficiency is improved, but data transmission reliability may be affected
Solution Approach 1:
The patent applies local quality by selectively stopping PUCCH transmission and PDCCH monitoring only during specific measurement gap periods and for specific cell groups, rather than globally suspending these functions. This allows the system to optimize resource allocation during measurement activities while maintaining data transmission reliability during non-measurement periods through localized control of transmission and monitoring functions.
