Joint Indication for DMRS Configuration in NR Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing radio communication technologies, particularly in the new radio (NR) physical layer, face challenges with high control signaling overhead and low flexibility due to the need for independent configuration of Demodulation Reference Signal (DMRS) parameters, leading to inefficiencies in system transmission.
Innovation Solution
The proposed solution involves using joint indication information to notify parameter information such as DMRS, Modulation and Coding Scheme (MCS), and Phase-Tracking Reference Signal (PTRS) through correlation among various parameter information, reducing control signaling overhead and increasing flexibility by jointly indicating these parameters.

Engineering Contradiction Analysis
1Adaptability or versatility
If independent configuration of DMRS parameters is used to achieve maximum flexibility, then adaptability is improved, but control signaling overhead increases
Solution Approach 1:
The patent combines multiple DMRS parameter configurations into a unified joint indication mechanism. Instead of independently signaling each parameter (DMRS type, length, position, etc.), the system merges them into a single joint indication value that simultaneously determines multiple parameters, thereby reducing control signaling overhead while maintaining configuration flexibility.
Solution Approach 2:
The joint indication mechanism serves multiple functions simultaneously: it indicates DMRS type, DMRS length, DMRS position, and other parameters all through a single indication value. This multi-functional approach allows the system to achieve maximum flexibility across multiple parameters without requiring separate control signals for each parameter.
2Adaptability or versatility
If independent configuration of DMRS parameters is used, then adaptability is improved, but device complexity increases
Solution Approach 1:
The patent merges the management of multiple DMRS parameters into a single joint indication framework. The base station and user equipment both use the same joint indication value to determine multiple parameters, simplifying the device complexity by eliminating the need for separate parameter management and configuration procedures.
Solution Approach 2:
The system changes from independently managing multiple parameters to managing a single joint indication value. This parameter transformation approach simplifies the configuration process by converting multiple independent parameter settings into a single unified parameter that automatically determines all DMRS-related configurations.
