A relay node (or relay station) assists in providing asymmetric communications with a mobile station. When resources are less than ideal for providing a direct uplink or downlink with the mobile station to a first base station, the relay station is employed to provide an uplink or downlink to a second base station. The mobile station may still maintain a direct downlink / uplink to the first base station when adequate resources are present. To assist in resource coordination the first and second base stations share scheduling information for the mobile station. This approach allows a second base station to server as a surrogate base station for a first base station, when inadequate resources are available for a direct uplink or downlink to the mobile station. The relay node makes it possible for the mobile station to maintain the uplink (or downlink) with the second base station, while remaining assigned to the first base station.
