Solution Overview

Problem

Extended Reality (XR) services are sensitive to transmission delay and jitter, leading to suboptimal Quality of Service (QoS) due to asynchronous arrival of multiple data streams.

Innovation Solution

A network device configures terminals to send uplink (UL) jitter information using configuration parameters, enabling resource scheduling and QoS parameter adjustments based on reported UL jitter, thereby synchronizing data arrival.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If multiple data streams are scheduled to arrive synchronously for XR services, then the QoS requirement is met, but transmission jitter causes asynchronous arrival and degrades QoS

Engineering Contradiction:
ImproveQoSVSAvoidtransmission jitter
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent implements a feedback mechanism where the terminal measures UL jitter and reports it to the network device. The network device uses this feedback to dynamically adjust scheduling parameters and QoS configurations, creating a closed-loop control system that compensates for transmission jitter and maintains synchronous arrival of data streams.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent applies preliminary action by having the network device proactively configure the terminal to measure and report UL jitter before QoS degradation occurs. The network device preemptively adjusts scheduling parameters based on predicted jitter patterns, preventing asynchronous arrival rather than reacting to it.

Inventive Principle:
Principle #10Preliminary action

2Productivity

If UL jitter information is collected and processed by the network device, then resource scheduling and QoS management are improved, but system complexity increases

Engineering Contradiction:
Improveresource scheduling efficiencyVSAvoidsystem complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent applies self-service by enabling the terminal to autonomously measure UL jitter and generate reports without requiring complex network-side measurement infrastructure. The terminal performs self-diagnosis of transmission quality and provides this information to the network device, simplifying the overall system architecture while maintaining high scheduling efficiency.

Inventive Principle:
Principle #25Self-service
