IAB Node Power Sharing Between DU and MT Cell Groups

The patent segments the power management by introducing a separate power coordination entity that handles power allocation independently from the transmission entities. The total available power is divided into separate power budgets for DU and MT components, with further segmentation for MCG and SCG. This segmentation allows simultaneous transmission while distributing the complexity of power management across multiple independent control layers.

The patent introduces a power coordination entity as an intermediary between the transmission entities (DU, MT MCG, MT SCG) and the power source. This intermediary receives transmission requirements from all entities, performs centralized power allocation calculations, and distributes appropriate power levels to each entity. This mediator approach resolves the complexity by centralizing the decision-making process while allowing distributed simultaneous transmission.

The patent creates a universal power sharing framework that can handle multiple connection scenarios (single connection, dual connectivity, multi-RAT) through a single unified power coordination entity. This entity implements adaptive power allocation that automatically adjusts to different connection configurations, making the system versatile while maintaining efficient power management across all scenarios.

The patent implements dynamic power allocation where the power coordination entity continuously monitors transmission requirements, channel conditions, and power availability, then adjusts power distribution in real-time. The power allocation parameters are dynamically updated based on current network conditions, enabling the system to adapt to changing multi-connection scenarios while optimizing power efficiency.
