DRX Wake-Up Signaling for Flexible UE Sleep Cycle Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The inflexibility of DRX parameter configuration in current communication systems leads to increased power consumption in User Equipment (UE) due to high probabilities of acquiring no data during blind detection on the Physical Downlink Control Channel (PDCCH), as the DRX parameters are not adjusted according to varying service requirements.
Innovation Solution
A method for a base station to generate and transmit a wake-up or go-to-sleep signal to indicate DRX parameters, such as CDRX, on-duration timer, and DRX cycle, to UE, allowing flexible adjustment based on service requirements, thereby reducing power consumption and data acquisition failures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If DRX parameter is configured by base station through high-layer signaling with fixed values, then device complexity is reduced, but adaptability to different service requirements deteriorates
Solution Approach 1:
The patent applies dynamics by transitioning from static fixed DRX parameter values to dynamic flexible parameter configuration. The base station can now dynamically adjust DRX parameters based on real-time service requirements and UE states, making the system adaptable while managing complexity through controlled dynamic behavior.
Solution Approach 2:
The patent implements parameter changes by allowing DRX parameters to vary based on different service types and UE conditions. Instead of using fixed values, the system changes parameters such as DRX cycle length, on-duration timer, and inactivity timer according to actual communication needs, thereby improving adaptability.
2Use of energy by moving object
If DRX parameter is configured with fixed values, then ease of operation is improved, but power consumption increases due to high probability of acquiring no data
Solution Approach 1:
The patent applies feedback mechanisms where the base station monitors UE activity patterns and service requirements, then adjusts DRX parameters accordingly. This feedback loop enables the system to reduce power consumption by optimizing parameter configuration based on actual data acquisition success rates and UE behavior.
Solution Approach 2:
The system dynamically adjusts DRX parameters based on real-time conditions rather than using fixed configurations. This dynamic adaptation allows the UE to achieve better power management by adjusting its monitoring behavior according to actual service needs, reducing unnecessary wake-ups and data acquisition failures.
3Productivity
If blind detection is performed by UE on PDCCH with fixed DRX parameter, then device complexity is minimized, but productivity deteriorates due to increased power consumption
Solution Approach 1:
The patent changes DRX parameters dynamically to optimize data acquisition efficiency. By adjusting parameters such as DRX cycle length and on-duration based on service requirements and UE states, the system improves productivity in data acquisition while maintaining manageable complexity through parameter optimization rather than fundamental mechanism changes.
