Abstract: PURPOSE: A mobile communication device including base station/mobile station multiple antennas is provided to reflect lower characteristics of spatial channels, and to transmit multiple stream data as forming antenna beams of a base station by considering lower characteristics of all mobile stations, thereby accomplishing maximum theoretical capacities. CONSTITUTION: A base station(10) restores weight information determined in mobile stations(20,22,...,24) from feedback signals, generates downlink control information, selects desired data of the mobile stations(20,22,...,24), and modulates/codes the selected data as controlling gains. The base station(10) spreads bands, operates a selected basis matrix by using the downlink control information, and transmits data signals, the first control signals, and pilot signals to the mobile stations(20,22,...,24). Each of the mobile stations(20,22,...,24) at least has one mobile station antenna. The base station(10) has at least two base station antennas. The number of the mobile station antennas is less than or more than the number of the base station antennas. The first characteristic corresponds to lower characteristics of base station/mobile station multiple antenna channels. The downlink control information consists of mobile station selection information, indexes of an optimal basis matrix, and indexes of an optimal gain value.
