Abstract
An embodiment method for power control in a multi-hop communications system includes transmitting a power usage pattern for each relay node in a subset of relay nodes served by a communications controller, where the power usage pattern specifies transmit power levels for the relay node while the relay node is operating in a power control mode. The method also includes receiving channel measurements of access links between the relay nodes in the subset of relay nodes and subscriber equipment served by the relay nodes, determining backhaul link transmit power levels and access link transmit power levels based on the channel measurements of access links and channel measurements of backhaul links between the communications controller and the relay nodes, and transmitting the access link power levels to the subset of relay nodes.
