Dynamic vDU Radio Resource Scheduling for RU Migration

The patent implements dynamic radio resource allocation by establishing a scheduler that monitors traffic conditions and vDU statuses in real-time, and dynamically adjusts resource allocation decisions. The scheduler determines allocation based on current traffic loads and vDU operational states, transitioning from static to dynamic allocation to optimize resource utilization and reduce power consumption.

The patent implements feedback mechanisms where the scheduler receives status information from vDUs and traffic condition data from the network, processes this feedback, and adjusts resource allocation accordingly. The system continuously monitors performance metrics and resource usage patterns, using this feedback to optimize allocation decisions and reduce energy waste.

The patent segments the scheduling function into a dedicated scheduler component that operates independently from vDU operations. The scheduler is divided into functional modules: traffic condition monitoring, vDU status monitoring, allocation decision-making, and resource assignment. This segmentation allows complex dynamic allocation to be managed through modular, manageable components.

The scheduler is designed as a universal control entity that handles multiple functions: monitoring traffic conditions, monitoring vDU statuses, determining allocation priorities, and coordinating resource assignments. This multi-functional design consolidates complexity into a single coordinated system rather than distributed complex logic in each vDU.

The patent implements preliminary actions by having the scheduler identify and prepare vDUs for potential scaling operations in advance. The system monitors traffic patterns and vDU loads to predict when scaling is beneficial, and prepares allocation plans before actual scaling occurs. This ensures that when scaling happens, communication continuity is maintained through pre-coordinated resource transitions.

The scheduler acts as an intermediary between vDU scaling operations and UE communications. It coordinates the scaling process by managing resource transitions, ensuring that UEs are seamlessly redirected between vDUs during scaling operations. The scheduler mediates the complexity of scaling by abstracting it from the communication layer, maintaining continuity through coordinated resource reallocation.
