A transmission method includes: selecting, from a cooperative cluster covered by a plurality of transmission points that transmit signals in cooperation with each other, a transmission point positioned in vicinity of a boundary between the cooperative cluster and another cooperative cluster; generating a first transmission weight that causes the selected transmission point to form a directional beam directed in a direction different from a direction of the another cooperative cluster; generating, by using the first transmission weight generated, a second transmission weight that weights transmission signals, such that signals that are transmitted simultaneously from the transmission points and addressed to a plurality of transmission destinations are separately received; generating, by using the second transmission weight generated, streams to be transmitted from the transmission points, the streams respectively corresponding to antennas; and transmitting the streams generated, from the transmission points.
