Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The asymmetrical service transmission in uplink and downlink directions of novel terminals in NR lite systems poses a challenge in satisfying the monitoring requirements for the control channel, as existing technologies do not effectively differentiate DRX configuration parameters for uplink and downlink services.
Innovation Solution
A method and apparatus for configuring distinct DRX configuration parameters for uplink and downlink services, including different durations for inactivity timers and short cycle timers, to accommodate the asymmetrical service transmission requirements of novel terminals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single DRX configuration parameter is used for both uplink and downlink services, then the device complexity is reduced, but the monitoring requirements for control channel in asymmetrical service transmission cannot be satisfied
Solution Approach 1:
The patent divides the single DRX configuration parameter into two separate parameters: a first DRX configuration parameter for uplink service and a second DRX configuration parameter for downlink service. This segmentation allows independent optimization of DRX parameters for each service direction, enabling the system to satisfy the monitoring requirements of asymmetrical service transmission while maintaining manageable configuration complexity through structured parameter separation.
2Reliability
If distinct DRX configuration parameters are configured for uplink and downlink services, then the monitoring requirements for control channel are satisfied, but the configuration complexity increases
Solution Approach 1:
The patent applies different DRX configuration parameters specifically tailored to the local characteristics of each service direction. The first DRX configuration parameter is optimized for uplink service characteristics, while the second DRX configuration parameter is optimized for downlink service characteristics. This local quality approach ensures that each service direction receives the appropriate DRX configuration to meet its specific monitoring requirements, justifying the increased configuration complexity through targeted optimization.
3Use of energy by moving object
If DRX configuration parameters are differentiated for uplink and downlink, then power management performance is optimized, but the parameter configuration complexity increases
Solution Approach 1:
The patent introduces dynamic DRX configuration parameters that can be independently adjusted for uplink and downlink services based on actual service conditions. The first DRX configuration parameter and second DRX configuration parameter can be dynamically modified to match the varying power management requirements of different service directions. This dynamic approach enables optimized power management performance while managing configuration complexity through structured parameter design that supports flexible adjustment.
