Abstract
A wireless communication apparatus includes a terminal selection unit that selects one or more user terminals, a prediction unit that derives 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 collection unit that, when the prediction value of the interference amount is less than a threshold value, collects reception power values of streams included in the stream group from the selected one or more user terminals, an antenna selection unit that selects the plurality of streams in descending order of reception power values and selecting the plurality of antennas associated with the plurality of selected streams, and a transmission unit that transmits the plurality of selected streams by beam forming using the plurality of selected antennas.
