Solution Overview
Problem
Current radio communication networks face challenges in dynamically adjusting time division duplex (TDD) communication configurations to accommodate sudden changes in traffic volume and uplink/downlink ratios, leading to inefficiencies and potential inter-cell interference.
Innovation Solution
Implementing a Radio Access Network (RAN) Intelligent Controller (RIC) that collects real-time traffic data from distributed units (DUs) to dynamically reconfigure subframe configurations across a cluster of cells, allowing for near-instantaneous adjustments in uplink and downlink resource allocation and slot formats to match changing network conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If TDD communication configurations are dynamically adjusted to accommodate sudden changes in traffic volume, then network capacity utilization improves, but inter-cell interference increases
Solution Approach 1:
The patent implements dynamic TDD configuration where the RIC controller continuously monitors traffic conditions and adjusts uplink/downlink subframe allocations in real-time based on current network demands, allowing the system to adapt flexibly to changing traffic patterns while maintaining optimal capacity utilization
Solution Approach 2:
The system employs feedback mechanisms where the RIC controller receives traffic condition reports from base stations, analyzes the data, and sends reconfiguration instructions back to adjust TDD settings, creating a closed-loop control system that responds to actual network conditions while coordinating across cells to minimize interference
2Speed
If subframe configurations are reconfigured in real-time to match changing network conditions, then network responsiveness improves, but system complexity increases
Solution Approach 1:
The RIC controller serves as an intermediary layer between the core network and base stations, centralizing the complex tasks of traffic analysis, decision-making, and reconfiguration coordination. This mediator handles the computational complexity of real-time adjustments while presenting a simplified interface to network elements, enabling fast responsiveness without distributing complexity across the entire system
Solution Approach 2:
The patent replaces traditional mechanical or manual configuration systems with an intelligent software-based RIC controller that uses automated algorithms and machine learning to analyze traffic patterns and make reconfiguration decisions, substituting complex manual coordination mechanisms with streamlined electronic control that achieves faster responsiveness
