Solution Overview

Problem

Existing wireless communication systems face challenges in efficiently managing split rendering configurations for user equipment (UEs) due to the lack of effective methods for balancing computing and power resource consumption with latency and quality requirements, particularly in scenarios involving heavy rendering workloads such as augmented and virtual reality experiences.

Innovation Solution

UEs and network nodes collaborate to determine and agree on split rendering configurations by exchanging parameters, allowing the network node to perform appropriate processing to balance computing, power, and latency requirements, thereby optimizing resource usage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by moving object

If split rendering configurations are implemented to balance computing and power resources, then energy consumption at UE is reduced, but system complexity increases due to parameter exchange and coordination requirements

Engineering Contradiction:
Improvepower consumption at UEVSAvoidconfiguration coordination complexity
Core Design Contradiction:
Use of energy by moving objectVSDevice complexity

Solution Approach 1:

The network node serves as an intermediary that receives rendering capability information from the UE, determines appropriate split rendering configurations, and communicates the selected configuration back to the UE. This mediator approach centralizes the decision-making process, reducing the complexity at the UE while still achieving energy optimization through coordinated split rendering.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system dynamically adjusts rendering parameters such as resolution, frame rate, and processing distribution based on UE capabilities, network conditions, and quality requirements. By changing these parameters adaptively, the system optimizes power consumption at the UE while maintaining acceptable rendering quality and meeting latency constraints.

Inventive Principle:
Principle #35Parameter changes

2Manufacturing precision

If more processing is performed at the network node, then rendering quality improves, but network bandwidth consumption increases

Engineering Contradiction:

Core Design Contradiction:
Manufacturing precisionVSQuantity of substance

Solution Approach 1:

The rendering process is segmented into different stages that can be distributed between the network node and the UE. Complex rendering tasks that require high quality are performed at the network node, while simpler post-processing and display operations are handled locally at the UE. This segmentation allows the system to achieve high rendering quality for critical tasks while minimizing overall network bandwidth consumption by reducing redundant data transmission.

Inventive Principle:
Principle #1Segmentation
