5G Transmission Parameter Configuration via DCI Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 5G New Radio technologies face inefficiencies in transmission parameter configuration, particularly in Dual-connection (DC) and Slot Aggregation (SA), where high signaling overhead and poor compatibility lead to reduced transmission efficiency and robustness, especially due to independent configuration of parameters across different links and slots.
Innovation Solution
A method and apparatus for flexibly configuring transmission parameters by classifying and determining values for transmission parameter sets, allowing for different configurations across resources while maintaining compatibility and reducing signaling overhead, through the use of control information carried in DCI (Downlink Control Information) that supports multiple values and configurations based on current application scenarios.

Engineering Contradiction Analysis
1Adaptability or versatility
If independent transmission parameter configuration is adopted for different links in Dual-connection, then flexibility is improved, but signaling overhead increases and compatibility deteriorates
Solution Approach 1:
The patent segments transmission parameters into different categories (common parameters and link-specific parameters) and configures them separately. Common parameters are configured once for multiple links, while link-specific parameters are configured independently, reducing redundant signaling overhead while maintaining necessary flexibility.
Solution Approach 2:
The patent creates a unified parameter configuration mechanism that can serve multiple links simultaneously. By defining common parameter sets that can be applied across different links, the system achieves universal configuration capability, reducing signaling overhead while maintaining compatibility across various receiving ends.
2Adaptability or versatility
If independent transmission parameter configuration is adopted for different links in Dual-connection, then flexibility is improved, but compatibility deteriorates
Solution Approach 1:
The patent segments transmission parameters into common parameters (configured once for all links) and link-specific parameters (configured independently). This segmentation ensures that receiving ends with limited compatibility can still process common parameters, while more advanced receiving ends can utilize link-specific parameters for enhanced flexibility.
Solution Approach 2:
The patent applies different configuration strategies to different parameter types based on their requirements. Common parameters use a unified configuration approach for broad compatibility, while link-specific parameters allow localized optimization for each link, achieving both compatibility and flexibility.
3Loss of information
If joint scheduling of multiple time domain resources is adopted in Slot Aggregation, then signaling overhead is reduced, but flexibility deteriorates
Solution Approach 1:
The patent introduces dynamic parameter adjustment capability within the joint scheduling framework. Transmission parameters can be dynamically changed for different slots or links based on current channel conditions and traffic requirements, allowing the system to adapt flexibly while maintaining the overhead-reducing benefits of joint scheduling.
Solution Approach 2:
The patent enables dynamic changes of transmission parameters (such as modulation and coding scheme, resource allocation) across different time domain resources within the aggregated slots. This parameter flexibility allows the system to optimize performance for each specific transmission instance while using a unified scheduling approach.
