Patent ID: 7324480

Claim:
A mobile communication system including a base station having multiple antennas and at least two mobile stations having multiple antennas, wherein the base station restores from feedback signals transmitted from the mobile stations weight information determined in the mobile stations, generates from the restored weight information downlink control information ensuring maximum throughput to each of the mobile stations, selects from among data of all of the mobile stations data of at least one desired mobile station to be transmitted, based on the downlink control information, selects from among the data of all of the mobile stations the data of each of the desired mobile stations based on the mobile station selection information, extracts from the selected data an amount of data of each of the desired mobile stations based on a predetermined bit size of each of the desired mobile stations, and combines the extracted data into frames with respect to each of the desired mobile stations; and each of the mobile stations has at least one mobile station antenna, the base station has at least two base station antennas, and the downlink control information includes mobile station selection information, an optimal basis matrix index, and optimal gain indices.
