A wireless communication apparatus includes a primary selection unit that selects a plurality of candidate terminals from among a plurality of terminals, based on signal-to-interference noise ratios of signals received from the plurality of terminals, a secondary selection unit that selects a plurality of transmission destination terminals from among the plurality of candidate terminals, based on channel estimate values of the candidate terminals, and a transmission processing unit that spatially multiplexes signals to be transmitted to the plurality of transmission destination terminals selected by the secondary selection unit, simultaneously on the same frequency.
