DRX Cycle Configuration for Video Service Frame Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 5G systems face additional data transmission delays due to mismatched DRX cycles with the arrival time intervals of video services, such as AR and VR, which require specific frame rates not aligned with default configurable DRX cycles.
Innovation Solution
A method for determining a Discontinuous Reception (DRX) cycle that matches the arrival time interval of service data by sending configuration information with a specified DRX cycle value different from default values, allowing for precise alignment and minimizing transmission delays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If default configurable DRX cycle values are used, then power consumption of UE is reduced, but additional data transmission delay is generated when DRX cycle does not match video service frame interval
Solution Approach 1:
The patent applies parameter changes by extending the DRX cycle configuration from fixed default values to include dynamically configurable values that can be adjusted according to specific video service requirements. The network device determines a customized DRX cycle value based on the video frame rate and other service parameters, then configures this customized value to the UE, allowing the DRX cycle to adapt to different video services while minimizing transmission delay.
2Productivity
If DRX cycle is configured to match video service frame interval, then transmission delay is minimized, but device complexity increases due to customized configuration
Solution Approach 1:
The patent implements dynamics by making the DRX cycle configuration adaptable and changeable based on service requirements. Instead of static default values, the system dynamically determines customized DRX cycle values according to video frame rates and service characteristics. The network device can adjust the DRX cycle configuration in real-time to match different video services, improving efficiency without requiring complex manual configuration.
3Reliability
If customized DRX cycle value is configured, then quality of video streaming service is improved, but loss of information increases due to non-standard configuration
Solution Approach 1:
The patent applies preliminary action by having the network device determine and configure the customized DRX cycle value before video service data transmission begins. The configuration information including the customized DRX cycle value is prepared in advance and sent to the UE, ensuring that both the network device and UE have consistent understanding of the DRX parameters before service starts, thereby preventing information loss during transmission.

AI summary
A method for determining a discontinuous reception (DRX) includes: sending configuration information of the DRX to a user equipment. A specified DRX cycle value contained in the configuration information is different from any one of default configurable DRX cycle values. The specified DRX cycle value may be determined in each subcarrier spacing (SCS) according to time domain resource allocation information corresponding to each SCS or may be based on the specified DRX cycle value in a specified SCS. In some methods, the specified DRX cycle value may be determined according to an arrival time interval of any one of service data, wherein the arrival time interval of the any one of the service data is different from any one of the default configurable DRX cycle values.
