Abstract
A MIMO wireless communication system capable of relaxing a reduction in a transmission rate on a cell end far from a base station and ensuring a high transmission rate for a mobile station, irrespectively of a distance from the base station is provided. In a state, the mobile stationchecks a propagation line quality and instructs only the first base stationto transmit data to the mobile station In a state, the mobile stationissues a request to divide the data to the first base stationand the second base stationand to transmit the divided data to the mobile station, and holds MIMO communication with the two base stations. In a state, the mobile stationrequests only the second base stationto transmit the data and communicates with the second base station
