Distributed Unit Interface Setup for Faster 6G Coordination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, particularly in 6G networks, efficient communication between distributed units (DUs) is challenging due to the lack of direct interfaces, leading to increased signaling delays and inefficient resource management when different vendors provide DUs with non-compatible frequency domains.
Innovation Solution
Establishing new communication interfaces and procedures for configuring spectrum aggregation between DUs, including the exchange of identification and cell information through setup request and response messages to facilitate seamless integration and resource management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If existing communication interfaces are used between DUs, then device complexity is reduced, but signaling delays increase and resource management efficiency deteriorates
Solution Approach 1:
The communication interface between DUs is segmented into multiple functional components: identification information exchange module, cell information exchange module, and setup response module. This segmentation allows each component to handle specific tasks independently, reducing overall signaling time while improving resource management efficiency through specialized processing functions.
Solution Approach 2:
The patent implements preliminary action by establishing identification information and cell information exchange mechanisms before actual resource allocation. The setup request message pre-configures communication parameters and the setup response message pre-establishes connection protocols, enabling faster subsequent resource management operations without repeated signaling.
2Adaptability or versatility
If DUs from different vendors with non-compatible frequency domains communicate, then system versatility improves, but coordination efficiency deteriorates
Solution Approach 1:
The patent introduces intermediary information exchange mechanisms that act as translators between DUs from different vendors. The identification information and cell information serve as standardized intermediaries that bridge incompatible frequency domains, enabling heterogeneous DUs to coordinate efficiently through a common information framework without requiring direct compatibility between all components.
Solution Approach 2:
The communication interface is designed with universal functionality to handle multiple vendor and frequency domain combinations. The setup request and setup response messages provide multi-functional support for various heterogeneous configurations, allowing a single interface design to accommodate diverse DU implementations while maintaining coordination efficiency through standardized information exchange protocols.

AI summary
A method performed by a first distributed unit (DU) is provided. The method includes transmitting, to a second DU, a setup request message through a communication interface between the first DU and a second DU and receiving, from the second DU, a setup response message, from the second DU, and wherein the setup response message includes at least one of identification information related to the second DU and address information related to the second DU.
