Sub-data Block Retransmission for Communication Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During data transmission, erroneous data blocks are often transmitted, leading to poor retransmission accuracy and inefficient use of transmission resources, as existing methods do not accurately identify and retransmit only the erroneous sub-data blocks.
Innovation Solution
A method where sub-data blocks that need retransmission are combined into a target data block when a predetermined condition is met, such as a specific number or service type, allowing for more accurate retransmission and efficient use of transmission resources by sending the combined blocks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the entire data block is retransmitted when errors occur, then the retransmission process is simple, but the retransmission accuracy is poor and transmission resources are wasted
Solution Approach 1:
The data block is divided into multiple sub-data blocks, allowing the system to identify and retransmit only the erroneous sub-data blocks rather than the entire data block. This segmentation enables precise error localization and targeted retransmission, improving retransmission accuracy while reducing unnecessary transmission of correct data.
Solution Approach 2:
The system extracts and identifies only the erroneous sub-data blocks from the data block and requests retransmission of these specific segments. By taking out only the problematic portions for retransmission, the system avoids wasting resources on correctly transmitted data while ensuring accurate retransmission of erroneous data.
2Reliability
If sub-data blocks are retransmitted separately, then retransmission accuracy is improved, but transmission resources are occupied inefficiently
Solution Approach 1:
Multiple erroneous sub-data blocks are combined into a single target data block for retransmission. This merging approach allows the system to transmit multiple corrected data segments in one retransmission operation, improving transmission efficiency by reducing the number of separate retransmission operations while maintaining the accuracy benefits of sub-data block-level correction.
Solution Approach 2:
The target data block serves multiple functions: it contains corrected sub-data blocks, provides accurate retransmission of erroneous data, and efficiently utilizes transmission resources by consolidating multiple retransmission operations into a single operation. This multi-functional approach optimizes both accuracy and efficiency.
3Productivity
If more sub-data blocks are combined into a target data block, then transmission efficiency is improved, but the complexity of determining combination conditions increases
Solution Approach 1:
The system uses predetermined conditions based on parameters such as the number of erroneous sub-data blocks and their service types to determine when to combine them into a target data block. By changing these parameters as combination criteria, the system achieves efficient consolidation while maintaining simple, rule-based decision logic that does not significantly increase complexity.

AI summary
The present disclosure provides a method and apparatus for transmitting data, pertaining to the technical field of communications. The method includes: receiving at least one retransmission request, wherein a retransmission request is configured to request retransmission of the erroneous sub-data blocks in the previously transmitted data block; combining the sub-data blocks that need to be retransmitted into a target data block when the sub-data blocks that need to be retransmitted satisfy a predetermined condition; and sending the target data block to a second communication device. According to the embodiments of the present disclosure, retransmission may be more accurately carried out for the erroneous data in the data block, and thus the retransmission accuracy is improved. Meanwhile, the merged sub-data blocks may be retransmitted in the form of the target data block, so that more data may be transmitted over an allocated transmission resource, not only the occupation of the transmission resources is reduced but also more data may be transmitted at one time over the transmission resource, thereby improving data transmission efficiency.
