Engineering Contradiction Analysis
1Reliability
If code block groups are used for data transmission, then reliability and decoding efficiency are improved, but resource allocation complexity increases because resources for transmitting modulation symbols of code block groups are not effectively defined
Solution Approach 1:
The patent segments the resource allocation process by defining separate resource indicators for different components. Specifically, it introduces a first resource indicator for modulation symbols and a second resource indicator for code block group indicators, allowing independent allocation and management of resources for each component. This segmentation resolves the complexity by breaking down the overall resource allocation into manageable parts while maintaining the reliability benefits of code block group processing.
2Productivity
If sequential data is mapped across time and frequency resources, then transmission efficiency is improved, but interference between adjacent resources increases
Solution Approach 1:
The patent applies local quality by assigning different resource allocation strategies to different parts of the transmission. It defines specific time-domain resources for modulation symbols and separate resources for code block group indicators, creating localized resource regions that minimize interference. This allows sequential data to be mapped efficiently across time and frequency while protecting adjacent resources from harmful interference through dedicated resource allocation.
