Dynamic DRX Configuration for XR Power Saving
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing DRX mechanisms in wireless communication systems, such as LTE and NR, face challenges in achieving optimal power saving for terminal devices, especially with the emergence of power-intensive services like Extended Reality (XR).
Innovation Solution
The proposed solution involves providing a first DRX configuration to a terminal device, causing it to activate and sleep with a first set of DRX parameters. During an activation duration based on the first set of DRX parameters, a second DRX configuration is provided, allowing the terminal device to sleep with a second set of DRX parameters, thereby enhancing power saving opportunities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the terminal device uses a traditional DRX mechanism with a single set of parameters, then the device complexity is low and ease of operation is good, but the power saving effect is insufficient for power-intensive services like XR
Solution Approach 1:
The patent divides the DRX mechanism into two distinct configurations: a first DRX configuration for general power saving and a second DRX configuration specifically optimized for power-intensive services like XR. This segmentation allows each configuration to be tailored for its specific purpose, enabling the terminal device to achieve better power saving during XR activities without compromising overall system simplicity.
Solution Approach 2:
The patent introduces dynamic switching between different DRX configurations based on service requirements. The terminal device can transition from the first DRX configuration to the second DRX configuration when power-intensive services are detected, and switch back when they are not. This dynamic adaptability allows the system to optimize power saving in real-time without requiring complex permanent configurations.
2Use of energy by moving object
If the terminal device enters sleep state more frequently to save power, then the power saving increases, but the service data transmission latency increases
Solution Approach 1:
The patent applies different DRX parameter settings locally according to service requirements. The second DRX configuration is specifically designed with parameters optimized for power-intensive services like XR, allowing the terminal device to maintain appropriate wake intervals for these services while still achieving power saving during other periods. This localized optimization ensures that power saving measures do not uniformly degrade all service performances.
