1. A method for downlink transmission synchronization in a cellular orthogonal frequency division multiplexing (OFDM), system, the method comprising:

  • (a) scanning and receiving one or more reference signals transmitted from a plurality of neighboring macro base stations by a femto base station;

    (b) determining a desired reference signal from the received one or more reference signals; and

    (c) configuring downlink radio signal transmission of the femto base station based on the desired reference signal such that the femto base station is synchronized with the plurality of neighboring macro base stations.
