XR DRX Cycle Control for Power Saving and PDU Timing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing Discontinuous Reception (DRX) mechanism in XR services fails to match the service characteristics, leading to inefficiencies in power saving and service data transmission.
Innovation Solution
Implementing a flexible DRX operation by defining two independent cycles - a first DRX cycle matching the XR service data burst and a second DRX cycle matching the PDU set, allowing terminals to activate or deactivate these cycles based on specific conditions and instructions from the network device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If a single DRX cycle is used for XR services, then the terminal can achieve power saving, but the service data transmission cannot be effectively ensured
Solution Approach 1:
The patent segments the single DRX cycle into two independent cycles: a first DRX cycle for data burst synchronization and a second DRX cycle for PDU set synchronization. This segmentation allows each cycle to independently manage different aspects of data transmission, ensuring both power saving and reliable service data delivery by aligning with the periodic characteristics of XR services.
Solution Approach 2:
The patent introduces dynamic adjustment mechanisms where the terminal can flexibly activate or deactivate the second DRX cycle based on actual transmission needs. The network device can also dynamically configure DRX parameters, allowing the system to adapt to varying service conditions and optimize the balance between power consumption and data transmission reliability.
2Reliability
If the terminal continuously monitors PDCCH subframes, then service data transmission is ensured, but power consumption increases
Solution Approach 1:
The patent implements periodic monitoring of PDCCH subframes synchronized with the first DRX cycle, which matches the periodic nature of XR data bursts. The terminal monitors PDCCH only during active periods defined by the DRX cycle, significantly reducing continuous monitoring and thus lowering power consumption while maintaining reliable data transmission through periodic wake-ups.
3Loss of energy
If the DRX cycle is aligned with data burst cycle, then power saving is optimized, but PDU set transmission timing may be compromised
Solution Approach 1:
The patent segments the DRX timing management into two independent cycles: the first DRX cycle aligns with data burst periodicity for power saving, while the second DRX cycle aligns with PDU set periodicity for precise transmission timing. This segmentation resolves the conflict by allowing each cycle to optimize for its specific function without compromising the other.
Solution Approach 2:
The patent incorporates feedback mechanisms where the terminal reports its DRX cycle status and transmission needs to the network device. Based on this feedback, the network dynamically adjusts DRX parameters and timing, ensuring that both power saving and transmission timing requirements are met through continuous optimization.
