Current wireless communication systems, particularly in 5G networks, face challenges in optimizing transport block delivery due to limitations in resource allocation and code block segmentation, which affect the efficiency and reliability of data transmission across varying code rates and quality of service requirements.
Innovation Solution
The method involves determining over-the-air resources available for sending a transport block and performing segmentation into smaller code blocks based on the determined resources and corresponding code rates, allowing for dynamic code block size adjustment to optimize data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If transport blocks are segmented into fixed-size code blocks using traditional methods, then the segmentation process is simple, but the data transmission efficiency and coding gains are limited due to inability to adapt to varying resources and code rates
Solution Approach 1:
The patent implements dynamic code block segmentation where the code block size is not fixed but adapts based on available over-the-air resources and code rate. The transmitting device determines the code block size dynamically by considering the transport block size, available resources, and target code rate, allowing the system to optimize transmission efficiency for varying channel conditions while maintaining manageable complexity through structured determination processes
Solution Approach 2:
The patent changes the parameter of code block size from a fixed value to a dynamically determined value based on multiple factors including transport block size, available over-the-air resources, and code rate requirements. This parameter adaptation enables the system to achieve better coding gains and transmission efficiency by matching code block characteristics to actual transmission conditions
2Reliability
If code block sizes are dynamically adjusted based on available resources and code rates, then coding gains and transmission efficiency are improved, but the determination and segmentation process becomes more complex
Solution Approach 1:
The patent applies preliminary action by having the transmitting device determine the available over-the-air resources and calculate the appropriate code block size before actual transmission begins. This advance determination allows the system to optimize segmentation based on current channel conditions and resource availability, improving transmission reliability without adding complexity during the actual transmission process
Solution Approach 2:
The system incorporates feedback mechanisms where the transmitting device monitors available over-the-air resources and adjusts code block segmentation accordingly. The determination of code block size is based on feedback about channel conditions, resource availability, and code rate requirements, enabling the system to maintain high reliability by adapting to actual transmission conditions
3Adaptability or versatility
If traditional fixed segmentation is used, then the processing is faster and simpler, but the peak data rates and adaptability to different quality of service requirements are limited
Solution Approach 1:
The patent applies segmentation by dividing the transport block into multiple code blocks with sizes that are determined dynamically rather than using fixed equal-sized segments. This segmentation approach allows different portions of data to be processed with appropriate code block sizes based on their specific requirements, improving adaptability to different QoS requirements while maintaining efficient processing through systematic determination methods
