1. A wireless communication apparatus, comprising:
a terminal selector configured to select one or more user terminals;
a predictor configured to derive a prediction value of an interference amount of a stream group transmitted from a plurality of antennas for the selected one or more user terminals;
a collector configured to, when the prediction value of the interference amount is less than a threshold value, collect reception power values of beams of a plurality of streams included in the stream group from the selected one or more user terminals;
an antenna selector configured to select the plurality of streams in descending order of the reception power values and select the plurality of antennas associated with the plurality of selected streams; and
a transmitter configured to transmit the plurality of selected streams by beam forming using the plurality of selected antennas.
