File Delivery Failure Feedback for Adaptive Wireless Services
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication systems face challenges in providing accurate file-level delivery failure feedback, leading to inefficient bandwidth usage and reduced reliability in services like extended reality (XR) due to the lack of direct file-level metrics and delayed feedback.
Innovation Solution
Implementing mechanisms for file delivery failure feedback and application feedback in wireless communication systems, allowing the radio access network (RAN) or user equipment (UE) to notify server entities or application clients about delivery failures, enabling adaptive adjustments such as changing compression schemes to optimize bandwidth usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If file-level delivery failure feedback is implemented in wireless communication systems, then reliability is improved, but device complexity increases
Solution Approach 1:
The feedback mechanism is segmented into different levels: packet-level acknowledgments at the lower layer and file-level delivery failure notifications at the upper layer. This segmentation allows the system to maintain simple packet-level operations while adding file-level reliability monitoring without overwhelming complexity throughout the entire system.
Solution Approach 2:
An intermediary feedback mechanism is introduced where the radio access network or user equipment generates file-level delivery failure notifications that are sent to server entities or application clients. This intermediary layer translates complex delivery status into simplified file-level failure indicators, improving reliability without directly increasing end-device complexity.
2Loss of energy
If real-time file-level feedback is implemented, then bandwidth efficiency is improved, but loss of time increases
Solution Approach 1:
The system performs preliminary actions by monitoring file delivery status continuously and preparing feedback information in advance. When a delivery failure is detected, the pre-prepared feedback can be sent immediately, reducing the actual feedback delay while maintaining bandwidth efficiency through proactive rather than reactive feedback generation.
Solution Approach 2:
The feedback mechanism is designed to be self-service in nature, where the system automatically generates and sends file-level delivery failure notifications without requiring manual intervention or complex coordination. This self-service approach reduces overhead and minimizes delays while efficiently utilizing bandwidth for essential feedback only.

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.
