XR Data Integrity Transmission via Segmented Scheduling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current XR service transmission methods, such as proportional fair scheduling, fail to ensure the integrity and accuracy of video frames, leading to unsatisfactory user experience due to incorrect frame rates and lack of consideration for the integrity of XR video frame transmission.
Innovation Solution
The proposed method involves configuring service feature information to identify XR services and prioritize data transmission based on the integrity requirements of video frames, slices, or tiles, ensuring that data packets are transmitted as a whole to maintain synchronization and accuracy, thereby improving user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If proportional fair scheduling is used for data transmission, then system fairness and resource utilization are improved, but the integrity and accuracy of XR video frame transmission deteriorate
Solution Approach 1:
The patent segments XR data into complete video frames, slices, or tiles as atomic transmission units. Each unit is configured with service feature information that identifies it as an XR service data unit requiring integrity transmission. This segmentation ensures that proportional fair scheduling operates on complete logical units rather than individual packets, preventing frame corruption while maintaining system-level resource utilization through configurable scheduling priorities.
2Speed
If data packets are transmitted individually without integrity consideration, then transmission speed and resource efficiency are improved, but the accuracy rate and user satisfaction of XR services deteriorate
Solution Approach 1:
The patent applies preliminary action by configuring service feature information and integrity requirements before data transmission begins. The network device identifies XR service data units, configures them with appropriate service feature information indicating integrity requirements, and establishes transmission parameters in advance. This preliminary configuration enables the system to maintain high transmission speeds while ensuring that complete video frames, slices, or tiles are delivered intact to the terminal without requiring post-transmission correction.
3Ease of operation
If conventional scheduling methods are used, then ease of operation and system compatibility are improved, but the synchronization and integrity of XR video data transmission deteriorate
Solution Approach 1:
The patent implements a universal scheduling mechanism that can handle both conventional services and XR services through a unified service feature information configuration framework. The network device configures service feature information that can indicate different service types and integrity requirements, allowing the same scheduling infrastructure to serve multiple purposes. This multi-functionality maintains ease of operation and system compatibility while enabling XR-specific integrity transmission through configurable parameters rather than requiring separate specialized systems.
