PROBLEM TO BE SOLVED: To notify a radio receiver device without increasing a control information amount whether a multi-user multiplex transmission signal transmitted from a radio transmitter device is multi-user MIMO or OFDMA.SOLUTION: The radio transmitter device includes: on the basis of information indicative of a multiplex system that each radio receiver device is compatible with, a group configuration unit 107 for generating a plurality of groups constituted by a plurality of radio receiver devices, determining a multiplex system to multiplexing data to be transmitted to the plurality of radio receiver devices subordinate to each group, and adding a preset identification number corresponding to the multiplex system to each group; a scheduling unit 115 for selecting one group from the groups; and a transmission symbol generator unit 125 for multiplexing the data, to be transmitted to the plurality of radio receiver devices subordinate to the selected group, with the multiplex system corresponding to the identification number added to the selected group, to transmit a transmission signal. |
