Transport Block Size Determination Using Resource Block Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for determining transport block size (TBS) in data transmission often result in calculated TBS being greater than the TBS actually used, leading to increased bit rates and reduced reliability of data transmission.
Innovation Solution
A method for determining TBS based on the number of target resource blocks, which is calculated by considering the number of first resource blocks configured for a data channel and the number of second resource blocks belonging to a first frequency domain resource, allowing for a more accurate determination of TBS.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the TBS is determined using existing methods based on total resource blocks configured for data channel, then the calculation is simple, but the calculated TBS is greater than the actual TBS used, leading to increased bit rates and reduced transmission reliability
Solution Approach 1:
The patent segments the resource blocks into two distinct categories: first resource blocks (configured for data channel) and second resource blocks (belonging to first frequency domain resource). This segmentation allows the TBS calculation to exclude second resource blocks that are not actually used for data transmission, thereby improving TBS determination accuracy while maintaining manageable complexity through clear classification criteria.
Solution Approach 2:
The patent applies local quality by treating different resource blocks with different characteristics. First resource blocks are identified as suitable for data channel transmission, while second resource blocks are identified as belonging to first frequency domain resources that are not used for data transmission. This differentiated treatment ensures that TBS calculation reflects the actual usable resources, improving accuracy without excessive complexity.
2Reliability
If the TBS is calculated using all configured resource blocks, then the calculation process is straightforward, but the configured bit rate deviates from the actual bit rate, reducing transmission reliability
Solution Approach 1:
The patent performs preliminary identification and classification of resource blocks before TBS calculation. By pre-categorizing resource blocks into first resource blocks (for data channel) and second resource blocks (for first frequency domain resource), the system ensures that only appropriate resource blocks are included in TBS calculation, thereby improving transmission reliability while managing complexity through advance organization.
Solution Approach 2:
The patent extracts and excludes second resource blocks from the TBS calculation process. By identifying and removing resource blocks that belong to first frequency domain resources (which are not used for data transmission) from the total count, the calculation focuses only on resource blocks that actually carry data, improving reliability by aligning configured bit rate with actual bit rate.
