Uplink QoS Flow Mapping for XR Data Integrity Scheduling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies fail to effectively address the challenge of ensuring quality of experience (QoE) and quality of service (QoS) in extended reality (XR) and tactile internet applications, particularly in reducing data packet loss during network transmission, which affects user experience.
Innovation Solution
A method and apparatus are provided to configure transmission resources and priorities based on integrity transmission requirements and data amounts, which involves receiving information from a terminal about data integrity and amount, and configuring transmission resources and priorities accordingly to minimize data packet loss and enhance network uplink efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If data packets are transmitted individually without integrity consideration, then transmission speed is improved, but data packet loss increases
Solution Approach 1:
The patent segments data into integrity groups where related data packets are treated as a collective unit. Each integrity group is assigned a unified priority level and transmission resource allocation, ensuring that packets within the same group maintain their relative integrity while allowing different groups to be transmitted in parallel, thus resolving the contradiction between transmission speed and data integrity.
Solution Approach 2:
The patent dynamically adjusts transmission parameters including priority levels, resource allocation, and scheduling decisions based on the integrity requirements of different data groups. By changing these parameters adaptively according to service types and network conditions, the system achieves both high transmission speed and reliable data integrity protection.
2Device complexity
If transmission resources are allocated uniformly to all data, then resource management simplicity is improved, but network uplink transmission efficiency deteriorates
Solution Approach 1:
The patent implements local quality differentiation by assigning different priority levels and resource allocation strategies to different integrity groups based on their specific requirements. Instead of uniform resource management, each integrity group receives customized transmission parameters, which optimizes network uplink transmission efficiency while maintaining manageable resource allocation through automated classification.
Solution Approach 2:
The system dynamically changes transmission parameters such as priority, resource block allocation, and scheduling timing based on the integrity requirements and network conditions of each data group. This adaptive parameter adjustment improves transmission efficiency without requiring complex manual resource management.
3Ease of operation
If priority-based scheduling is implemented for all data packets, then transmission priority control is improved, but network resource waste increases
Solution Approach 1:
The patent segments data into integrity groups with differentiated priority requirements. Only necessary high-priority groups receive enhanced priority scheduling resources, while lower-priority groups use standard scheduling. This segmented approach provides effective priority control capability while avoiding widespread network resource waste by applying priority treatment only where genuinely needed.
Solution Approach 2:
The system applies priority-based scheduling selectively to specific integrity groups that require it, rather than uniformly to all data packets. This partial application of priority scheduling provides adequate control capability for critical data while minimizing network resource waste by avoiding excessive priority treatment for non-critical data.
Data Source
AI summary
In an uplink transmission method for extended reality (XR) services, user equipment (UE) notifies a base station that a data flow of a current service has an uplink integrity transmission requirement. The base station maps a QoS flow having the uplink integrity transmission requirement to a corresponding radio bearer, and notifies the UE of the corresponding radio bearer through a signaling configuration. The UE then reports, through a MAC CE, a data amount of the service flow having the integrity transmission requirement.
