1. A communication device that performs beamforming, the communication device comprising:
an antenna array configured to simultaneously form a first vertical beam and a second vertical beam for an arbitrary time;
a transceiver configured to transmit and receive a signal using a double beam including the first vertical beam and the second vertical beam; and
a processor configured to determine, using a K-means interference avoidance (KIA) algorithm, a first optimal vertical tilting angle of the first vertical beam based on Inter-Beam Interference (IBI) of the second vertical beam, and determine a second optimal vertical tilting angle of the second vertical beam based on the IBI of the first vertical beam,
wherein the KIA algorithm is an algorithm using K-means clustering in which the IBI is included as a variable of an objective function, and is configured to cluster user equipments into a first cluster including at least one user equipment and a second cluster including at least one user equipment in a single cell.
