Title: RADIO COMMUNICATION APPARATUS AND RADIO COMMUNICATION METHOD
Abstract:
A radio communication apparatus (1) is characterized by comprising: a primary selection unit (201) that selects, from among a plurality of terminals (2), a plurality of candidate terminals on the basis of the signal-to-interference noise ratio of a signal received from each of the plurality of terminals (2); a secondary selection unit (202) that selects, from among the plurality of candidate terminals, a plurality of transmission counterpart terminals on the basis of a transmission path estimation value of each of the candidate terminals; and a transmission processing unit (10) that spatially-multiplexes, using the same frequency and simultaneously, signals to be transmitted to the plurality of transmission counterpart terminals selected by the secondary selection unit (202).
