Abstract
To suppress an adverse effect caused by side lobes of an antenna array when determining an AWV to be used in communication. A first communication device transmits/receives a training signal while scanning a beam pattern, and a second communication device receives/transmits the training signal with a fixed beam pattern. A primary DOD/DOA in the first communication device is determined based on the transmission/reception result of the training signal. Then, second round training is performed. In this point, the first communication device transmits/receives the training signal while scanning a beam pattern in a state where transmission to the primary DOD or reception from the primary DOA is restricted. A secondary DOD/DOA is determined based on the result of the second round training. An AWV corresponding to the primary DOD/DOA and an AWV corresponding to the secondary DOD/DOA are selectively used in communication between the first and second devices.
