Abstract:
Various embodiments disclosed herein provide for power control system in a multi-hop integrated access and backhaul network. In a multi-hop integrated access and backhaul network a donor node can communicate with user equipment devices and relay nodes that have varying power levels, and to avoid receiving uplink transmissions with varying power levels which can impact automatic gain control systems and lower overall throughput, the power control system disclosed herein can manage the power levels of the relay node in order to reduce the difference in power levels. In one embodiment, the power control system can schedule relay node devices to transmit uplink transmissions alongside UE devices that have a high signal strength. In another embodiment, the power control system can schedule relay nodes and UE devices to separate symbols within a time slot. In another embodiment, the power control system can perform closed loop power control management at the relay node to reduce the power level for the uplink transmission.
