Host Central Unit Load Relay for Enterprise Spectrum Interference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing 5G networks face interference challenges in overlapping regions of neighboring enterprise networks operating on the same spectrum, affecting user signal quality and reliability, particularly for critical applications like Ultra-Reliable Low-Latency Communications (URLLC) and Industrial Internet of Things (IIoT).
Innovation Solution
A central unit at a host network acts as a proxy or arbitrator to coordinate and relay load information between neighboring enterprise networks, managing interference by synchronizing uplink and downlink transmissions, arbitrating resource requests, and ensuring non-overlapping resource allocation based on service level agreements (SLAs) to minimize interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple enterprise networks operate on the same spectrum in overlapping regions, then spectrum utilization efficiency is improved, but interference between networks increases
Solution Approach 1:
The host network's central unit acts as an intermediary between neighboring enterprise networks, relaying load information and coordinating resource allocation to manage interference while enabling coexistence on the same spectrum
Solution Approach 2:
The system implements feedback mechanisms where enterprise networks share load information with the host network, which then coordinates resource allocation based on this feedback to minimize interference and optimize spectrum utilization
2Productivity
If enterprises share load information directly, then coordination efficiency is improved, but system complexity increases
Solution Approach 1:
The host network's central unit serves as a mediator that simplifies the coordination process by centralizing the exchange of load information, thereby maintaining coordination efficiency while reducing the complexity that would arise from direct peer-to-peer interactions between multiple enterprise networks
3Object-affected harmful factors
If the host network coordinates all resource allocation, then interference management is improved, but control overhead increases
Solution Approach 1:
The host network's central unit focuses coordination efforts specifically on overlapping regions where interference occurs, rather than uniformly managing all resources across the entire network, thereby improving interference management while reducing unnecessary control overhead in non-overlapping areas

AI summary
Systems and methods manage interference between different enterprises operating over the same wireless spectrum. The system includes central units of a host, a first enterprise, and a second enterprise. A first interface connects the central unit of the host to the central unit of the first enterprise. A second interface connects the central unit of the host to the second enterprise. The central unit of the host is configured to relay load information between the first and second enterprises to limit interference between each enterprise when the first and second enterprises are operating on the same spectrum and in an overlapping coverage region. The central unit of the host arbitrates transmission requests from the enterprises based on information from service level agreements (SLAs) shared between the central unit at the host and enterprises.
