Solution Overview

Problem

Conventional systems for augmented reality (AR) split rendering in 5G communication systems fail to provide timely and accurate performance information from user equipment (UE) to servers, leading to inconsistencies in AR experiences due to performance changes in UE devices, which can result in delayed or mismatched virtual and real object displays.

Innovation Solution

A method and device for capability-based split computing that detects abnormal device status through environment and performance parameters, transmitting UE capability information to a server, and receiving adjusted content and processes to ensure optimal performance, allowing for dynamic adjustment of processing complexity based on UE capabilities.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If the UE processes high-complexity content locally, then processing quality is improved, but device heat generation increases and performance deteriorates

Engineering Contradiction:
Improveprocessing qualityVSAvoiddevice heat generation
Core Design Contradiction:
Manufacturing precisionVSTemperature

Solution Approach 1:

The patent divides the rendering process into two segments: complex rendering computations are performed on the server, while the UE only handles lightweight tasks such as pose correction and final image composition. This segmentation allows high-quality rendering without overloading the UE's processing capabilities, thereby preventing excessive heat generation and performance deterioration.

Inventive Principle:
Principle #1Segmentation

2Loss of energy

If the UE capability information is not transmitted to the server, then network communication overhead is reduced, but AR rendering consistency deteriorates

Engineering Contradiction:
Improvenetwork communication overheadVSAvoidAR rendering consistency
Core Design Contradiction:
Loss of energyVSReliability

Solution Approach 1:

The patent implements a feedback mechanism where the UE periodically transmits its capability information (processing performance, temperature, power consumption) to the server. The server uses this feedback to dynamically adjust the rendering complexity and content delivery strategy, ensuring that the UE can consistently render AR content without overload while maintaining rendering quality and consistency.

Inventive Principle:
Principle #23Feedback

3Productivity

If the processing complexity is dynamically adjusted, then device performance is maintained, but system complexity increases

Engineering Contradiction:
Improvedevice performanceVSAvoidsystem complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent introduces dynamic adjustment of processing complexity based on real-time UE capability feedback. The server continuously monitors UE status (temperature, power consumption, processing performance) and adapts the rendering complexity accordingly. This dynamic approach maintains optimal device performance under varying conditions while the increased system complexity is managed through automated server-side control algorithms.

Inventive Principle:
Principle #15Dynamics
