Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in efficiently managing measurements on deactivated secondary Component Carriers (SCCs) due to power consumption and interference issues, particularly in next-generation networks requiring higher data rates and lower latency.
Innovation Solution
The method involves configuring a subset of measurement timing occasions for performing deactivated SCC measurements, allowing interruptions only during specific SMTC durations, and using bitmaps or additional SMTC configurations to indicate these occasions, thereby optimizing power usage and minimizing interference with primary and activated cells.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If deactivated SCC measurements are performed frequently to ensure measurement accuracy and network optimization, then measurement precision is improved, but power consumption increases
Solution Approach 1:
The patent implements periodic measurements by configuring specific measurement timing occasions (SMTC) where deactivated SCC measurements are performed only at predetermined intervals rather than continuously. The network configures a measurement cycle with specific periodicity, and the UE performs measurements only at these scheduled occasions, reducing power consumption while maintaining adequate measurement accuracy for network optimization decisions.
Solution Approach 2:
The patent applies partial action by performing measurements on only a subset of deactivated SCCs at each measurement occasion rather than all deactivated SCCs continuously. The network can configure different measurement cycles for different SCCs, and the UE performs measurements selectively based on configuration, reducing overall power consumption while maintaining necessary measurement coverage.
2Productivity
If deactivated SCC measurements are performed continuously to maintain real-time network optimization, then productivity is improved, but interruptions to primary and activated cells increase
Solution Approach 1:
The patent schedules measurements at periodic intervals using configured SMTC occasions rather than continuous measurements. This timing-based approach ensures that measurements occur only during designated windows, preventing continuous interruptions to primary and activated cells while still providing periodic updates for network optimization.
Solution Approach 2:
The network configures measurement timing occasions in advance, specifying when measurements should occur before the actual measurement takes place. This preliminary configuration allows the UE to plan measurement activities ahead of time, ensuring they occur during appropriate windows without causing unexpected interruptions to primary and activated cell operations.
3Measurement precision
If measurement timing occasions are increased to improve measurement coverage, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent uses a universal bitmap-based configuration mechanism that can indicate subsets of measurement timing occasions for multiple deactivated SCCs simultaneously. This multi-functional approach allows a single configuration structure to handle various measurement scenarios and SCC combinations, reducing overall configuration complexity while maintaining comprehensive measurement coverage.
Solution Approach 2:
The patent segments the measurement configuration into manageable components: a measurement cycle defining the overall period, SMTC occasions defining specific measurement windows within the cycle, and bitmaps indicating which occasions to use. This segmentation allows complex measurement patterns to be built from simpler, standardized building blocks, reducing configuration complexity.
