Enterprise Network Interface Coordination for Shared-Spectrum Interference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G networks, overlapping transmissions between neighboring enterprises operating in the same spectrum cause interference, affecting user signal quality and requiring effective interference management to ensure low latency and reliable communications.
Innovation Solution
A system and method for minimizing interference by coordinating transmissions between enterprises using a central unit that shares load information and allocates bandwidth based on service level agreements, enabling grant-free scheduling and power boosting for Ultra-Reliable Low-Latency Communications (URLLC) and Industrial Internet of Things (IIoT) devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple enterprises operate in the same spectrum in neighboring localities, then spectrum utilization is improved, but interference between enterprises increases
Solution Approach 1:
The patent introduces a host network operator as an intermediary that coordinates resource allocation between multiple enterprises. The host manages spectrum resources and enterprise access, enabling multiple enterprises to operate simultaneously while controlling interference through centralized resource management and coordination mechanisms.
Solution Approach 2:
The system dynamically adjusts transmission parameters such as power levels, resource block allocations, and modulation schemes based on enterprise load conditions and interference measurements. This allows spectrum utilization to be maximized while maintaining acceptable interference levels through adaptive parameter optimization.
2Productivity
If enterprises share spectrum resources, then bandwidth efficiency is improved, but signal quality deteriorates due to interference
Solution Approach 1:
The patent implements enterprise-specific resource allocation where each enterprise is assigned particular resource blocks, time slots, or frequency ranges within the shared spectrum. This local differentiation allows bandwidth efficiency through sharing while maintaining signal quality by reducing co-channel interference through spatial and spectral separation.
Solution Approach 2:
The system employs feedback mechanisms where enterprises report signal quality metrics and interference levels to the host network operator. The host uses this feedback to dynamically reallocate resources, adjust power levels, or modify transmission parameters to maintain signal quality while preserving bandwidth efficiency.
3Object-affected harmful factors
If centralized coordination is implemented for interference management, then interference reduction is improved, but system complexity increases
Solution Approach 1:
The host network operator performs multiple functions including resource allocation, interference coordination, enterprise authentication, and quality of service management through a single centralized entity. This multi-functionality reduces overall system complexity by consolidating coordination tasks rather than requiring separate mechanisms for each function.

AI summary
System and methods manage interference between different enterprises operating over the same spectrum. The system includes a central unit of a first enterprise associated with a first cell site and a central unit of a second enterprise associated with a second cell site. An interface connects the central unit of the first enterprise to the central unit of the second enterprise and transmits load information. A central unit of either enterprise is configured to share load information without requiring a standard form between each enterprise via the interface to minimize interference between each enterprise when both enterprises are operating on the same spectrum and in an overlapping coverage region.
