Attribute-Based Buffer Status Reporting for Packet Prioritization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current buffer status reporting (BSR) methods in communication systems do not fully consider the diverse characteristics of different data packets, such as importance degrees and time to expiration, leading to inefficient resource allocation.
Innovation Solution
The terminal device generates separate BSRs for data packets with different attributes, including service type, time to expiration, and importance degree, allowing the network device to allocate resources based on these attributes, and includes time information only in specific BSRs to reduce transmission overhead.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate BSRs are generated for data packets with different attributes, then resource allocation reliability is improved, but transmission overhead increases
Solution Approach 1:
The patent segments the buffer status reporting by creating separate BSR reports for different data packet attributes (service type, time to expiration, importance degree). This segmentation allows the network device to allocate resources more reliably based on specific packet characteristics, while the BSR MAC CE structure efficiently organizes these segmented reports to manage overhead.
Solution Approach 2:
The patent applies local quality by including attribute-specific information (service type, time to expiration, importance degree) in relevant BSR reports rather than uniformly reporting all attributes for all packets. This allows targeted resource allocation decisions based on the specific characteristics of each data packet group, improving reliability without proportionally increasing overall overhead.
2Measurement precision
If time information is included in all BSRs, then transmission timing accuracy is improved, but transmission resource consumption increases
Solution Approach 1:
The patent applies local quality by including time information (time to expiration attribute) only in BSR reports where timing accuracy is critical for resource allocation decisions. The BSR MAC CE structure allows selective inclusion of time information based on the data packet attributes being reported, ensuring timing accuracy is improved only where necessary while minimizing overall transmission resource consumption.
3Manufacturing precision
If multiple BSRs are sent separately, then resource allocation precision is improved, but transmission delay increases
Solution Approach 1:
The patent merges multiple attribute-specific BSR reports into a single BSR MAC CE structure that can be transmitted together. This combining approach maintains the precision of attribute-specific resource allocation reporting while reducing transmission delay by sending all BSR information in one unified message rather than multiple separate transmissions.
4Measurement precision
If BSR reporting frequency is increased, then buffer status accuracy is improved, but network device processing load increases
Solution Approach 1:
The patent segments buffer status reporting by attribute types (service type, time to expiration, importance degree), allowing the network device to process and prioritize different attribute groups differently. This segmentation enables more accurate buffer status monitoring while managing processing load by organizing information in a structured BSR MAC CE format that facilitates efficient parsing and decision-making.
Data Source
AI summary
A buffer status reporting method includes: buffering a plurality of data packets, where the plurality of data packets includes a first data packet and a second data packet; and sending a first buffer status report and a second buffer status report to a network device, where the first buffer status report indicates a buffer status of the first data packet, and the second buffer status report indicates a buffer status of the second data packet. The first data packet and the second data packet differ in at least one of the following attributes: a service type, time to expiration, an importance degree of a protocol data unit set to which the data packet belongs, and a type of the protocol data unit set to which the data packet belongs.
