Inter-DU Interface Setup for Carrier Aggregation Coordination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, particularly in 6G networks, there is a challenge in efficiently managing and configuring carrier aggregation (CA) and dual connectivity (DC) between distributed units (DUs) from different vendors due to lack of direct interfaces, leading to signaling delays and inefficient resource management.
Innovation Solution
Implementing new interfaces and procedures for configuring spectrum aggregation between DUs, including DU group setup requests and responses, to facilitate efficient communication and resource management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If new interfaces and procedures are implemented for configuring spectrum aggregation between DUs, then resource management efficiency is enhanced and signaling delays are reduced, but device complexity and implementation difficulty increase
Solution Approach 1:
The patent segments the base station functionality into Central Units (CU) and Distributed Units (DU), allowing independent configuration and management of each unit. This segmentation enables standardized interfaces between vendors while maintaining overall system efficiency, resolving the contradiction by organizing complexity into manageable, standardized modules.
Solution Approach 2:
The patent implements universal interface procedures that can be applied across different vendor equipment and multiple DU scenarios. The standardized setup request/response messages and configuration procedures provide multi-functional capability that works for intra-vendor and inter-vendor scenarios, enhancing resource management efficiency without proportionally increasing complexity.
2Speed
If direct interfaces are established between DUs from different vendors, then communication efficiency improves and signaling delays are reduced, but compatibility and interoperability challenges increase
Solution Approach 1:
The patent introduces standardized interface procedures and message formats as intermediaries between DUs from different vendors. These standardized protocols act as a common language that enables direct communication while ensuring compatibility, allowing fast inter-DU signaling without sacrificing interoperability reliability.
Solution Approach 2:
The patent defines specific parameters and information elements that must be exchanged between DUs through the standardized interface. By standardizing these parameters (such as DU group setup requests, cell information, capability information), the system achieves reliable interoperability while maintaining communication efficiency.
