Claim Text:
1. A method of a transmission apparatus for transmitting data to a reception apparatus using a plurality of antennas, comprising: forming a beam into a predetermined direction using the plurality of antennas; repeatedly transmitting a training signal to the reception apparatus while sequentially changing a direction of the formed beam, each transmission being in a different direction, and receiving at least one response signal from the reception apparatus with respect to the transmitted training signals; determining a number of channel responses based on a magnitude and a time interval of each of the at least one response signal; determining presence of a multipath based on the determined number of channel responses, and a magnitude and a direction of each of the at least one response signal; and determining a data transmission scheme, which is one of based on the determined number of channel responses and the determined presence of a multipath, for transmitting the data to the reception apparatus.
