Abstract
A system and method for distributed power control in a communications system are provided. A method for relay node operations includes transmitting a signal at a transmit power level on a first channel from a relay node to a user equipment, receiving a message comprising a first indication of channel quality of the first channel at the transmit power level, and determining a second indication of channel quality of a second channel between a communications controller and the relay node, where the first channel and the second channel are in a same multi-hop communication path. The method also includes altering the transmit power level of the first channel based on the first indication of channel quality and the second indication of channel quality to converge the channel quality of the first channel to a convergence value.
