Abstract
A wireless base station device includes a plurality of transmit weight generation sections and a beam selection section. The transmit weight generation sections generate pieces of transmit weight information used for spatial division multiplexing transmission according to different algorithms. The pieces of transmit weight information are generated based on channel information on a plurality of terminals each having one or more antennas with which the wireless base station device performs spatial division multiplexing transmission. The beam selection section selects one of the pieces of transmit weight information generated.
