BSR Table Signaling for Accurate Uplink Resource Scheduling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication technologies face challenges in accurately scheduling resources for terminals due to insufficient analysis of buffer status report (BSR) values, leading to resource wastage and transmission delays, especially in supporting big data services like extended reality (XR) with increasing uplink data.
Innovation Solution
A method and apparatus that enable terminals to send indication information about the BSR table used, allowing network devices to accurately analyze the BS value, thereby enabling precise resource allocation and reducing waste and delays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the terminal reports BSR using a standard BSR table with index values, then the reporting process is simple and fast, but the network device cannot accurately determine the actual buffer size leading to resource allocation inefficiency
Solution Approach 1:
The patent introduces indication information as an intermediary element that bridges the terminal and network device. This indication information explicitly specifies which BSR table the terminal uses, allowing the network device to accurately interpret the BSR index and determine the actual buffer size without increasing the fundamental BSR reporting structure.
Solution Approach 2:
The patent changes the parameter representation by adding table identification information to the BSR report. Instead of relying solely on the index value within a standard table, the system now includes parameters that indicate which specific table configuration is being used, enabling precise buffer size determination while maintaining the efficiency of index-based reporting.
2Productivity
If the network device allocates resources based on estimated buffer size from BSR index, then resource allocation is quick, but resource wastage and transmission delays occur due to inaccurate scheduling
Solution Approach 1:
The patent implements a feedback mechanism where the terminal provides indication information about the BSR table configuration to the network device. This feedback loop enables the network device to accurately interpret the buffer status report and make precise resource allocation decisions, thereby improving resource utilization efficiency and reducing wastage.
Solution Approach 2:
The patent replaces the mechanical estimation process with an information-based determination system. Instead of the network device guessing or estimating buffer size from generic BSR indices, the system substitutes this with explicit table identification information that allows precise calculation of actual buffer size, leading to more efficient resource allocation and reduced resource wastage.
