Wireless Communication Node Data Volume Reporting for XR Services
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems, particularly for XR services, face challenges in efficiently scheduling uplink resources due to limitations in the Buffer Status Report (BSR) mechanism, which cannot accurately report data volumes for XR services, leading to delays and suboptimal user experience.
Innovation Solution
A method for data volume reporting in wireless communications that involves transmitting a signaling with a field indicating the data volume of a packet set, where each packet is associated with an identifier other than a Logical Channel Group (LCG) Identifier, allowing for independent reporting of data volumes not dependent on LCGs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the existing BSR mechanism is used for uplink resource scheduling, then the system maintains compatibility with current protocols, but it cannot meet the low delay and high data rate demands of XR services
Solution Approach 1:
The patent segments the data volume reporting by introducing separate BSR triggers for different packet types (e.g., video packets, audio packets, control data). Each packet type can be reported independently, allowing the base station to allocate resources more precisely for XR services without waiting for aggregate LCG-based reports, thereby reducing service response time while maintaining protocol compatibility.
Solution Approach 2:
The patent implements dynamic BSR triggering mechanisms that adapt to XR service characteristics. When XR data arrives or when delay thresholds are approached, BSR reports are triggered dynamically rather than following fixed LCG intervals. This dynamic adaptation enables the system to respond quickly to XR service demands while maintaining backward compatibility with existing scheduling frameworks.
2Measurement precision
If the BSR mechanism reports total data volume per LCG, then the reporting structure remains simple and manageable, but it cannot provide accurate data volume information for packets with dependencies
Solution Approach 1:
The patent employs a nested reporting structure where LCG-based BSR reports contain or reference more granular packet-type-specific data volume information. The outer LCG framework maintains simplicity for overall resource management, while nested inner reports provide precise data volume breakdowns for dependent packets (e.g., video frames with their associated audio and control data). This nested approach enables accurate measurement without overwhelming system complexity.
Solution Approach 2:
The patent introduces an intermediary data structure that bridges the gap between simple LCG reporting and detailed packet-level information. This intermediary layer aggregates packet-specific data volumes and presents them in a structured format that maintains the simplicity of LCG-based reporting while enabling precise measurement of dependent packet groups. The intermediary structure allows the base station to understand data volume accuracy requirements without increasing overall reporting complexity.
