<P>PROBLEM TO BE SOLVED: To provide technique capable of suppressing interference to be given to a communication partner apparatus which is not a transmission destination, when beam forming is performed so as to transmit a signal. <P>SOLUTION: A communication part 13 performs communication by using multiple antennas 110a. When transmission signals are transmitted, the communication part 13 performs beam forming concerning transmission directivity in the multiple antennas 110a, based on received known signals. The communication part 13 performs control to reduce transmission power in transmitting the transmission signals in accordance with time intervals from the reception of the known signals to the transmission of the transmission signals. <P>COPYRIGHT: (C)2012,JPO&INPIT |
