vDU Reassignment for Interfering Radio Units in 5G Networks

The patent segments the base station functionality into separate virtualized units (vDU1, vDU2, etc.) that can be independently managed and allocated. By dividing the control functions into modular virtual units, the system can eliminate interference through coordinated management without requiring complex direct control between physical base stations, as each vDU can be independently optimized and managed by the management apparatus.

The management apparatus acts as an intermediary between multiple vDUs, coordinating their operations to eliminate interference. Instead of requiring direct control communication between base stations, the management apparatus mediates the coordination, assigning vDUs to specific RUs and managing resource allocation centrally, thereby reducing control complexity while maintaining interference elimination capabilities.

The patent implements dynamic assignment of vDUs to RUs based on real-time conditions. The management apparatus can flexibly allocate and reassign virtualized DUs to different RUs as needed, allowing resource allocation flexibility while maintaining simple interference management through centralized control. This dynamic allocation enables the system to adapt to changing conditions without increasing interference management complexity.

The virtualized DU architecture provides multi-functionality, where a single vDU can be assigned to serve multiple RUs across different physical base stations. This universal vDU design allows flexible resource allocation while simplifying interference management, as the same vDU can coordinate its operations across multiple RUs under centralized management, eliminating the need for complex inter-base-station control.
