Enhanced BSR Scheduling for High-Volume XR Buffer Reporting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing buffer status report (BSR) in 5G wireless communication systems is insufficient to handle the high data traffic volume of extended Reality (XR) services, leading to inefficient data reporting and large padding requirements.
Innovation Solution
A scheduling method that enhances BSR by extending the buffer index and range of BSR types, allowing for more precise data reporting through configuration information sent via dedicated signaling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the existing BSR is used for reporting, then the structure is simple and compatible with current systems, but the data reporting capacity is insufficient for high traffic volume XR services
Solution Approach 1:
The patent segments the BSR into two types: traditional BSR for general data reporting and enhanced BSR specifically for XR services. The enhanced BSR further segments the buffer status information into multiple fields including buffer index, data volume, and quality of service parameters, allowing specialized high-capacity reporting without redesigning the entire BSR structure.
Solution Approach 2:
The patent adds new dimensions to the BSR structure by incorporating quality of service parameters, buffer index extensions, and data volume fields that were not present in traditional BSR. This dimensional expansion enables the BSR to handle XR service requirements while maintaining backward compatibility with existing 5G networks.
2Measurement precision
If the existing BSR is used, then the implementation is simple, but large padding is required due to insufficient data reporting precision
Solution Approach 1:
The patent changes key parameters of the BSR structure by extending the buffer index from 5 bits to 8 bits, adding data volume fields with precise granularity, and incorporating quality of service parameters. These parameter changes enable precise data reporting for XR services without requiring excessive padding, thereby reducing energy consumption.
3Productivity
If enhanced BSR is implemented, then data reporting efficiency is improved and padding is reduced, but configuration complexity increases
Solution Approach 1:
The patent designs the enhanced BSR to serve multiple functions: reporting buffer status for XR services, indicating data volume with precise granularity, providing quality of service information, and maintaining compatibility with existing 5G networks. This multi-functionality achieves high data reporting efficiency while managing configuration complexity through a unified structure.
