Abstract
A radio communication system includes a plurality of radio communication terminals each of which includes a plurality of first antennas, and a radio communication apparatus including a plurality of second antennas, an acquisition unit configured to acquire a plurality of channel response values between the first antennas and the second antennas, a setting unit configured to set, based on the channel response values, a plurality of MIMO parameters, and a transmission unit configured to perform multicast transmission to each of the radio communication terminals via the second antennas, based on the MIMO parameters. The multicast transmission is performed based on a multiple-input multiple-output (MIMO) transmission scheme. Each of the radio communication terminals further includes a receiving unit which receives data transmitted from the radio communication apparatus by the multicast transmission.
