Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face inefficiencies in cell discontinuous transmission (DTX) and discontinuous reception (DRX) processes, particularly in 5G NR and LTE technologies, which impact power consumption and network performance due to suboptimal management of transmission and reception states.
Innovation Solution
Enhancements to physical and MAC layer processes for DTX/DRX patterns are implemented, allowing for dynamic adaptation and optimization of transmission and reception states in wireless devices and base stations, enabling more efficient power management and improved network performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cell DTX/DRX processes are continuously monitored and managed, then network performance and reliability are improved, but power consumption increases
Solution Approach 1:
The patent implements periodic monitoring and management of cell DTX/DRX processes instead of continuous monitoring. The network entity periodically updates DTX/DRX configurations and monitors cell states at scheduled intervals, allowing the wireless device to enter low-power states during intervals while still maintaining network performance through periodic check-ins and updates.
2Use of energy by moving object
If transmission and reception states are frequently adjusted for optimization, then power consumption is reduced, but system complexity and management overhead increase
Solution Approach 1:
The patent enables the wireless device to autonomously adjust its transmission and reception states based on pre-configured DTX/DRX parameters and local conditions. The device can self-manage its power states without requiring complex centralized control for every state transition, reducing overall system complexity while achieving power optimization through localized decision-making.
3Productivity
If DTX/DRX patterns are dynamically adapted, then power consumption and network efficiency are improved, but control signaling overhead increases
Solution Approach 1:
The patent employs preliminary configuration of DTX/DRX patterns and parameters through RRC signaling before dynamic adaptation is needed. The network entity pre-configures multiple DTX/DRX patterns with different parameters, and the wireless device can switch between these pre-configured patterns based on local conditions without requiring extensive real-time control signaling, thus reducing signaling overhead while maintaining dynamic adaptability.
