209 when receiving common control signals as input reception weight creating section 210 creates reception weight to maximize the reception power snr of the common control signal based on the channel matrix obtained by channel condition estimating section 204 and obtains the common control signal by combining outputs from receiving sections 202 1 to 202 ns using this reception weight reception weight creating section 210 outputs the common control signal to control information extracting section 211 control information extracting section 211 extracts control information contained in the common control signal that is resource assignment information mode information and precoding information used in terminals connected at the same time when multiuser mimo transmission is performed outputs precoding information among these pieces of information to reception weight creating section 210 and outputs resource assignment information to data extracting section 212 when receiving dedicated data sequence signals as input reception weight creating section 210 obtains the dedicated data sequence signal directed to terminal 200 by combining outputs from receiving sections 202 1 to 202 ns using the reception weight created by precoding information in the present embodiment a dedicated data sequence signal contains a dedicated control signal and a dedicated data sequence and received weight creating section 210 outputs the dedicated control signal to control information extracting section 211 and outputs the dedicated data sequence to data extracting section 212 control information extracting section 211 outputs mcs information and so forth contained in a dedicated control signal and data extracting section 212 demodulates and decodes a dedicated data sequence according to this information here in fig6 although receiving antennas 201 1.
