DRX Parameter Configuration for Concurrent 5G Services
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G mobile communication networks, determining reasonable DRX configuration parameters for multiple concurrent services is a challenge, as existing methods do not effectively manage power consumption and data transmission stability when handling diverse service types with different quality of service requirements.
Innovation Solution
A method for determining target DRX parameters by either the terminal or network-side device, based on the DRX parameters of individual services, which involves selecting the maximum or highest-priority service parameters to configure the Inactivity Timer and other timers, ensuring stable data transmission and power management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the terminal continuously monitors the PDCCH channel, then data transmission stability is improved, but power consumption increases
Solution Approach 1:
The patent implements DRX mechanism where the terminal periodically wakes up to monitor PDCCH channel during On-Duration periods and enters sleep state during Off-Duration periods. This periodic monitoring approach allows the terminal to balance between data transmission stability and power consumption by checking for scheduled services at regular intervals rather than continuously monitoring.
Solution Approach 2:
The patent dynamically adjusts DRX parameters including On-Duration time, Off-Duration time, and monitoring frequencies based on the types and priorities of concurrent services. When high-priority services are detected, the terminal increases monitoring frequency and extends On-Duration periods, while for low-priority services it reduces monitoring to save power, making the monitoring behavior adaptive to real-time service requirements.
2Use of energy by moving object
If the terminal enters sleep state frequently, then power consumption is reduced, but communication delay increases
Solution Approach 1:
The patent uses Inactivity Timer and RTT Timer to predict when data transmission is likely to occur and proactively wakes up the terminal before actual data arrives. The Inactivity Timer extends monitoring periods when recent activity suggests more data is coming, while the RTT Timer schedules wake-ups based on expected retransmission timing, preventing the terminal from sleeping too deeply and missing time-critical data.
Solution Approach 2:
The patent dynamically changes DRX parameter values including On-Duration length, cycle periods, and timer thresholds based on service priority and traffic patterns. For delay-sensitive services, the system increases On-Duration time and decreases sleep intervals, while for power-sensitive applications it extends sleep periods, allowing flexible trade-off adjustment between power consumption and communication delay based on real-time requirements.
3Adaptability or versatility
If different DRX parameters are configured for each service, then service quality is improved, but system complexity increases
Solution Approach 1:
The patent merges multiple service-specific DRX configurations into a unified DRX parameter set by selecting parameters based on service priority levels and types. Instead of maintaining separate DRX configurations for each concurrent service, the terminal evaluates all active services and determines a single optimal DRX configuration that satisfies the most demanding service requirements, reducing configuration complexity while maintaining service quality.
Solution Approach 2:
The patent applies different DRX parameter strategies to different service types locally within the unified configuration framework. High-priority services receive more aggressive monitoring parameters (longer On-Duration, shorter cycles) while lower-priority services accept more conservative settings, allowing each service type to receive customized treatment through priority-based parameter selection without requiring completely separate configuration systems.
4Reliability
If the terminal monitors the control channel more frequently, then data loss is reduced, but power consumption increases
Solution Approach 1:
The patent uses feedback from service detection and HARQ acknowledgments to dynamically adjust monitoring frequency. When the terminal detects scheduled services or receives NACK feedback indicating unsuccessful data reception, it increases monitoring frequency and extends On-Duration periods to ensure reliable data delivery. Conversely, when no services are scheduled or ACK feedback is received, it reduces monitoring frequency to conserve power, creating a closed-loop system that adapts monitoring intensity to actual data transmission needs.
