DCI Block Segmentation Across Resources for URLLC Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems face challenges in ensuring high reliability and low latency for ultra reliable low latency communication (URLLC) services, particularly in the transmission of downlink control information (DCI) due to varying service requirements.
Innovation Solution
The method involves dividing DCI into multiple data block groups and configuring specific transmission resources for each group, allowing for block transmission and improving reliability and accuracy by sequencing and preprocessing the data blocks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If DCI is transmitted as a single block, then the transmission process is simple, but the reliability and accuracy of information transmission cannot be ensured for URLLC services
Solution Approach 1:
The DCI is divided into multiple data blocks that are transmitted separately through different transmission resources. This segmentation allows the system to improve reliability by ensuring that at least some blocks are received correctly, while the complexity is managed through systematic division and reconstruction processes at the receiver end.
2Reliability
If DCI is divided into multiple data block groups and transmitted through different resources, then the reliability and accuracy of information transmission are improved, but the transmission process becomes more complex
Solution Approach 1:
The DCI is divided into multiple data block groups that are transmitted through different transmission resources. This segmentation enables improved accuracy by distributing transmission risks across multiple channels, while the complexity is managed through systematic grouping and reconstruction processes.
Solution Approach 2:
The data blocks are pre-processed and organized into groups before transmission, with predetermined transmission resources allocated to each group. This preliminary organization reduces the complexity during actual transmission by establishing a structured framework in advance.
3Reliability
If multiple transmission resources are allocated for DCI data blocks, then the reliability of URLLC service is enhanced, but the resource consumption increases
Solution Approach 1:
By dividing DCI into multiple data block groups and allocating them to different transmission resources, the system enhances reliability through diversified transmission paths. The resource consumption is optimized by ensuring that not all resources need to succeed for successful decoding.
Solution Approach 2:
The system changes the transmission parameters by using multiple transmission resources with different characteristics. This allows optimization of resource allocation based on channel conditions, improving reliability while managing resource consumption through adaptive parameter selection.
