1. A method of operating a communication device, the method comprising:
sweeping a plurality of first reception beams;
measuring reference signals, received from another communication device, based on the plurality of first reception beams;
estimating a downlink channel gain based on the measured reference signals and reception array response information corresponding to reception antenna characteristics of the communication device;
generating a downlink channel related matrix based on the downlink channel gain and the reception array response information;
determining a second reception beam based on the downlink channel related matrix;
determining a transmission beam based on at least one of the downlink channel gain, the downlink channel related matrix and the second reception beam; and
performing communication with the other communication device using the second reception beam and the transmission beam.
