Dynamic UE Sleep Modes for 5G DRX Power Saving
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G systems, User Equipment (UE) experiences relatively short sleep times and high power consumption due to fixed DRX configuration parameters, despite using the Discontinuous Reception (DRX) mechanism to reduce power consumption.
Innovation Solution
A method for determining a sleep state is introduced, where the UE receives sleep indication information from a base station and enters a sleep state, selecting a different mode based on this information. This allows the UE to dynamically adjust its sleep state without affecting quality of service, thereby reducing power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the UE uses the DRX mechanism with fixed configuration parameters, then the UE can enter a sleep state periodically, but the sleep time is relatively short and power consumption remains high
Solution Approach 1:
The patent applies dynamics by making the sleep state configuration adjustable rather than fixed. The base station can dynamically indicate different sleep modes to the UE through downlink control information, allowing the sleep duration and behavior to adapt to varying network conditions and traffic patterns, thereby extending sleep time while maintaining acceptable power consumption levels
Solution Approach 2:
The patent implements parameter changes by modifying the DRX configuration parameters dynamically. The base station can change sleep mode parameters (such as sleep duration, wake-up timing, and PDCCH monitoring behavior) based on current system conditions, enabling the UE to achieve longer sleep periods without compromising network responsiveness or increasing power consumption excessively
2Use of energy by moving object
If the UE enters a sleep state with extended duration, then power consumption is reduced, but the quality of service may be affected due to fixed DRX parameters
Solution Approach 1:
The patent employs feedback mechanisms where the base station monitors network conditions and UE state, then provides appropriate sleep mode indications through downlink control information. This closed-loop approach ensures that extended sleep periods do not compromise quality of service, as the base station can adjust sleep configurations based on actual network demands and UE responsiveness
Solution Approach 2:
The patent uses dynamics to enable flexible adaptation of sleep state parameters. By allowing the base station to dynamically indicate different sleep modes, the system can balance power savings with quality of service requirements in real-time, ensuring that extended sleep durations do not negatively impact service reliability or network responsiveness

AI summary
A method for determining a sleep state, a terminal, and a readable medium. The method for determining a sleep state comprises: receiving sleep instruction information sent by a base station; and on the basis of the sleep instruction information, entering a sleep state and selecting different modes. By application of the solution, a UE can be flexibly instructed to enter a sleep state without affecting the quality of service, thereby reducing the power consumption of the UE, and achieving the purpose of power saving.
