Application Feedback for Reliable XR File Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication systems, particularly in 5G NR, face challenges in efficiently handling file delivery failures and adapting to temporary degradations in data packet communication, leading to inefficiencies in bandwidth utilization and reliability for services like extended reality (XR) due to the lack of file-level feedback mechanisms.
Innovation Solution
Implementing methods and apparatuses that provide file delivery failure feedback and temporary degradation notifications to application clients or servers, allowing for adaptive adjustments in communication parameters, such as changing compression schemes, to improve delivery success and optimize bandwidth usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If file delivery failure feedback mechanisms are implemented, then delivery reliability is improved, but system complexity increases
Solution Approach 1:
The patent implements feedback mechanisms where the network entity sends file delivery failure notifications to the application client, and the application client sends application feedback to the network entity. This feedback loop enables the system to detect and respond to delivery failures, improving reliability by allowing retransmission or alternative delivery methods while maintaining manageable complexity through standardized feedback message formats.
Solution Approach 2:
The patent introduces feedback messages as intermediary elements that carry information between the network entity and application client. These feedback messages serve as standardized intermediaries that simplify the interaction complexity by providing a uniform interface for reporting delivery failures and conveying application-level information, thus improving reliability without proportionally increasing system complexity.
2Productivity
If adaptive traffic flows are implemented, then bandwidth utilization is improved, but control complexity increases
Solution Approach 1:
The patent implements adaptive traffic flows that dynamically adjust communication parameters based on feedback. The application client modifies transmission strategies, compression schemes, or data prioritization in response to delivery failure notifications, optimizing bandwidth utilization for different network conditions while managing control complexity through automated adaptation algorithms.
Solution Approach 2:
The patent enables adaptive adjustment of communication parameters such as compression schemes, data segmentation, and transmission timing based on network conditions and feedback received. By changing these parameters dynamically, the system optimizes bandwidth utilization for file delivery while keeping control complexity manageable through parameter-based adaptation rather than fundamental system redesign.
3Reliability
If file-level feedback mechanisms are implemented, then delivery reliability is improved, but information processing overhead increases
Solution Approach 1:
The patent segments feedback information into specific categories such as delivery failure notifications, file identification, and application-level status reports. By segmenting the feedback mechanism into discrete, standardized message types, the system improves reliability through comprehensive file-level tracking while minimizing information processing overhead through efficient, structured data formats that avoid redundant information transmission.

AI summary
Certain aspects of the present disclosure provide techniques for file delivery feedback and/or application feedback for certain application services. An example method generally includes communicating files with a user equipment (UE), each of the files having a plurality of packets, determining that a delivery failure occurred for at least one of the files, and sending, to a server entity, a notification of the delivery failure.
