File-Aware Wireless Communication for XR QoS
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication technologies, such as 5G NR, face challenges in supporting extended reality (XR) applications that require high bit rates, high reliability, and low latency, as they are primarily packet-centric, whereas XR services operate on a file-centric basis, leading to inaccuracies in handling file-level quality of service (QoS) requirements.
Innovation Solution
The implementation of file-aware communication techniques that determine target metrics like file error rate (FER) and file delay budget (FDB) for each file, allowing network entities to communicate packets according to these metrics, ensuring that all packets of a file meet the required QoS, rather than converting packet-level metrics, which can result in inaccurate handling of file-level requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If packet-centric communication is used in 5G NR, then network compatibility and existing protocol support are improved, but file-level QoS handling accuracy deteriorates
Solution Approach 1:
The patent segments the file transmission process into packet-level operations with file-level coordination. Individual packets are transmitted using existing packet-centric protocols, while a file transmission manager coordinates retransmissions and QoS management at the file level, ensuring both network compatibility and accurate file-level QoS handling.
Solution Approach 2:
The patent introduces a file transmission manager as an intermediary layer between the packet transmission protocol and the application layer. This intermediary translates file-level QoS requirements into packet-level transmission parameters and coordinates retransmissions, bridging the gap between packet-centric network protocols and file-centric application requirements.
2Adaptability or versatility
If packet-level metrics are used for communication, then existing network protocol compatibility is improved, but file-level QoS requirements accuracy deteriorates
Solution Approach 1:
The patent implements feedback mechanisms where the file transmission manager monitors packet transmission status and file-level QoS metrics, then adjusts retransmission strategies and communication parameters accordingly. This closed-loop control ensures accurate file-level QoS fulfillment while maintaining compatibility with existing packet-level protocols.
Solution Approach 2:
The patent dynamically changes communication parameters such as retransmission timing, priority levels, and resource allocation based on file-level QoS requirements. By adjusting these parameters at the file level while using standard packet protocols, the system achieves both protocol compatibility and precise QoS control.
3Productivity
If individual packet handling is used, then network resource flexibility is improved, but file-level QoS coordination deteriorates
Solution Approach 1:
The patent merges individual packet handling with file-level coordination by grouping packets belonging to the same file and applying coordinated QoS management to the group. This allows network resources to be flexibly allocated to individual packets while ensuring file-level QoS requirements are met through combined retransmission and priority management.
