Abstract
An exemplary method of communicating includes a relay node that uses a cell identifier that is also used by a base station having a coverage area within which the relay node is located. The method includes determining that a mobile station is within a communication range of the relay node. A transmission power from the relay node is controlled so that the total transmission power of at least one transmission from the relay node and the base station corresponds to a selected transmit power limit. A timing of a downlink transmission from the base station and the relay node is coordinated based on a schedule determined by the base station. At least one uplink control parameter is set at the base station based upon uplink information regarding a link between the mobile station and the relay node.
