COMMUNICATION DEVICE, COMMUNICATION METHOD, AND COMMUNICATION SYSTEM

摘要

The present invention relates to a communication device, a communication method, and a communication system capable of increasing a channel capacity at each cell edge of a plurality of cells. Data transmission by transmission stations (1-1, 1-2) which are base stations of adjacent cells is performed by MIMO transmission. A relay station (2) receives radio waves transmitted by both the transmission station (1-1) and the transmission station (1-2), and acquires data transmitted by the transmission station (1-1) and data transmitted by the transmission station (1-2). The relay station (2) performs data transmission to reception stations in adjacent cells by multi user MIMO transmission. The data transmitted from the transmission station (1-1) is received by the reception station (3-1) through the relay station (2), and the data transmitted from the transmission station (1-2) is received by the reception station (3-2) through the relay station (2). The present invention can be applied to a cellular system.
