1. A method for power control in a multi-hop communications system, the method comprising:

  • transmitting a power usage pattern for each relay node in a subset of relay nodes served by a communications controller, wherein the power usage pattern specifies transmit power levels for the relay node while the relay node is operating in a power control mode;

    receiving channel measurements of access links between each relay node in the subset of relay nodes and subscriber equipment served by the relay node;

    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 each relay node in the subset of relay nodes; and

    transmitting the access link power levels to the subset of relay nodes.
