UL Jitter Feedback for XR Uplink QoS Synchronization
Find Innovative SolutionsGenerate Solutions
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
Engineering 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
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.
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.
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
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.
