Transport Block Size Determination Using Available Channel Resources
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for determining Transport Block Size (TBS) for semi-statically configured channels do not consider the differences in available resources between channels, leading to inaccurate and inflexible TBS determination.
Innovation Solution
Determine TBS based on the number of resources of a first part of resources in a pre-configured transmission resource, excluding a second part of resources not used for channel transmission, to adapt to available resources and improve accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If TBS is determined based on the total number of transmission resources for a channel, then the determination process is simple, but the accuracy is poor because it does not account for unavailable resources
Solution Approach 1:
The transmission resource is divided into two segments: the first part of resources that are actually available for channel transmission and the second part of resources that are not available. The TBS determination is then based only on the number of resources in the first part, not the total. This segmentation allows accurate TBS calculation while maintaining simple implementation by clearly distinguishing between usable and unusable resources.
Solution Approach 2:
The unavailable resources (second part of resources) are extracted from the total transmission resource set. By removing these irrelevant resources from consideration, the patent focuses only on the first part of resources that are actually available for transmission, thereby improving TBS determination accuracy without complicating the overall process.
2Adaptability or versatility
If TBS is determined using a fixed transmission resource allocation, then the process is straightforward, but the flexibility to adapt to different channel conditions is reduced
Solution Approach 1:
The patent introduces dynamic adaptation by allowing the transmission resource to be divided into different parts based on actual channel conditions. The first part of resources represents the dynamically determined available resources, while the second part represents unavailable resources. This dynamic division enables the system to adapt to varying channel conditions while maintaining a relatively simple determination process.
Solution Approach 2:
Different parts of the transmission resource are assigned different qualities: the first part of resources has the quality of being available for transmission, while the second part has the quality of being unavailable. This local differentiation allows the system to maintain simplicity in the overall process while achieving flexibility in adapting to specific channel conditions through selective resource utilization.
3Reliability
If all pre-configured transmission resources are used for channel transmission, then resource utilization is maximized, but transmission abandonment occurs when resources are unavailable
Solution Approach 1:
The transmission resource is segmented into the first part of resources (available for transmission) and the second part of resources (not available). By using this segmentation, the system can reliably determine which resources to actually use for transmission, preventing transmission abandonment while optimizing resource utilization efficiency through selective allocation of only the first part of resources.
Solution Approach 2:
The patent implements feedback mechanisms that inform the system about the availability status of transmission resources. Based on this feedback, the system adjusts the transmission resource allocation by focusing only on the first part of resources that are confirmed to be available, thereby improving both transmission reliability and resource utilization efficiency by avoiding attempts to transmit on unavailable resources.
