发明名称	WIRELESS COMMUNICATION SYSTEM AND WIRELESS COMMUNICATION METHOD
摘要	A base station includes: a MIMO precoding section (32) for converting transmission data addressed to a mobile station to two data streams that respectively correspond to two reception antennas included in the mobile station, by performing MIMO precoding on the transmission data; a weight calculating section for calculating a transmission weight to be used for forming a directivity pattern directed toward each of the two reception antennas; and a weighting/combining section (34) for generating two combined data streams that are to be supplied to the respective antennas (20-1 and 20-2), by weighting each of the two data streams with the transmission weight calculated with respect to the reception antenna of the mobile station that corresponds to the data stream, and combining the two weighted data streams for each of the antennas (20). The two combined data streams are respectively transmitted from the antennas (20-1 and 20-2).

主权项	1. A transmission device comprising: a plurality of transmission antennas; weight calculating means for calculating a transmission weight with respect to each of a plurality of reception antennas of a reception device so that the plurality of transmission antennas form a directivity pattern directed toward the each of the plurality of reception antennas; and receiving means for receiving, by the plurality of transmission antennas, a plurality of known reference symbols having a low correlation thereamong transmitted from the plurality of reception antennas at the same frequency and at the same timing, wherein the weight calculating means calculates, based on the plurality of known reference symbols received by the plurality of transmission antennas, the transmission weight for forming the directivity pattern in which, with respect to the each of the plurality of reception antennas, a main beam is directed toward the each of the plurality of reception antennas and a null is directed toward the reception antenna other than the each of the plurality of reception antennas.
