<P>PROBLEM TO BE SOLVED: To provide a wireless communication terminal and directivity control method thereof in which processing power consumption can be suppressed as low as possible when remaining capacity of a battery is reduced. <P>SOLUTION: In accordance with information of a communication class contained in the signal of a control channel sent from a base station, a communication class determination section 2 determines whether the signal sent therefrom indicates data or a voice. A remaining battery power determination section 4 determines whether the remaining capacity of a terminal battery is equal to or less than a threshold. When the remaining capacity of the battery is equal to or less than the threshold and the communication class indicates voice communication, a transmitting and receiving mode switching section 5 carries out transmission and reception using a single antenna among a plurality of antennas. When the remaining capacity of the battery is equal to or less than the threshold and the communication class indicates data communication, control is carried out as an adaptive array antenna while using the plurality of antennas. <P>COPYRIGHT: (C)2010,JPO&INPIT |
