Distributed Unit Interface Setup for Cross-Vendor Spectrum Aggregation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, efficient spectrum aggregation between distributed units (DUs) from different vendors is hindered by the lack of compatible interfaces, leading to signaling delays and inefficient resource management.
Innovation Solution
Establishing new interfaces and procedures for spectrum aggregation, including the exchange of setup request and response messages between DUs, which include global IDs and identification information to facilitate seamless communication and resource coordination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If new interfaces and procedures are established for spectrum aggregation between DUs from different vendors, then resource management efficiency and system performance are improved, but device complexity and implementation difficulty increase
Solution Approach 1:
The patent establishes a universal interface framework that enables spectrum aggregation between DUs from different vendors through standardized message exchanges (setup request/response messages). This universal interface allows the system to aggregate spectrum resources across heterogeneous equipment while maintaining consistent communication protocols, thereby improving resource management efficiency without requiring vendor-specific implementations.
Solution Approach 2:
The patent introduces standardized interface messages (setup request and setup response messages containing global IDs and identification information) as intermediaries between DUs from different vendors. These intermediary messages facilitate seamless communication and coordination of spectrum resources by providing a common language for interaction, reducing the complexity of direct vendor-specific interfaces.
2Productivity
If spectrum aggregation is implemented between DUs from different vendors, then spectrum utilization is improved, but signaling delays occur due to lack of compatible interfaces
Solution Approach 1:
The patent implements preliminary action by establishing the interface setup procedure before actual spectrum aggregation operations. The setup request and response messages exchange identification information and global IDs in advance, creating a pre-configured compatible interface between DUs. This preliminary interface establishment eliminates signaling delays during subsequent spectrum aggregation operations, as the communication pathway is already validated and configured.
3Adaptability or versatility
If standardized interfaces are implemented for spectrum aggregation, then adaptability between different vendors is improved, but implementation cost and complexity increase
Solution Approach 1:
The patent creates a universal interface standard that enables DUs from different vendors to interoperate through common message formats (setup request/response with global IDs). This universality allows a single interface design to work across multiple vendor implementations, improving vendor compatibility while avoiding the need for multiple vendor-specific interface implementations, thereby managing complexity.

AI summary
An electronic device and memory for storing instructions for a first distributed unit (DU) are provided. The electronic device includes, when the instructions are executed on the first DU, the instructions that cause the first DU to transmit a setup request message to a second DU through a communication interface between the first DU and the second DU, and receive a setup response message from the second DU. The setup request message includes a global identity (ID) for a base station of the first DU, first identification information about the first DU at the base station, and cell information about each cell of one or more first cells of the first DU. The setup response message includes a global ID for a base station of the second DU, second identification information about the second DU at the base station, and cell information about each cell of one or more second cells of the second DU.
