Uplink Control Resource Segmentation for 5G NR
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G NR systems, the simultaneous transmission of uplink control information for different services with varying reliability requirements, such as eMBB and URLLC, is not efficiently supported, leading to discarded information and retransmissions, which impacts system efficiency.
Innovation Solution
A method is provided where a terminal device or network device determines a first transmission resource comprising two independent sub-resources for simultaneously transmitting uplink control information, allowing for the concurrent transmission of multiple pieces of uplink control information, including eMBB and URLLC, by allocating separate sub-resources based on their distinct reliability requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If uplink control information for different services is transmitted on the same PUCCH resource, then transmission efficiency is improved, but resource allocation becomes complex and unreliable transmission cannot be guaranteed
Solution Approach 1:
The PUCCH resource is segmented into multiple independent sub-resources (first transmission sub-resource and second transmission sub-resource). Each sub-resource is independently allocated to different uplink control information based on service requirements, enabling simultaneous transmission while maintaining clear resource boundaries and simplifying allocation management.
2Productivity
If uplink control information for different services is transmitted on the same PUCCH resource, then transmission efficiency is improved, but transmission reliability for services with high reliability requirements cannot be guaranteed
Solution Approach 1:
Different sub-resources are assigned different quality characteristics based on service requirements. High-reliability services (e.g., URLLC) are allocated sub-resources with higher reliability parameters, while other services use sub-resources optimized for their specific needs. This enables each service to receive appropriate transmission quality while maintaining overall system efficiency.
3Productivity
If multiple pieces of uplink control information are transmitted simultaneously, then system efficiency is improved, but information may be discarded and retransmissions occur
Solution Approach 1:
Multiple pieces of uplink control information are assigned to different segmented sub-resources for simultaneous transmission. This segmentation ensures that each information piece has its own dedicated transmission path, eliminating the information loss and retransmission issues that occur when multiple information pieces share the same resource.
