    • Disclosed is a method for transmitting a signal in a mobile communications system using a plurality of transmit/receive antennas. A method for transmitting a signal in accordance with an embodiment of the present invention comprises the steps of: a receiving end’s calculating a signal to interference noise ratio (SINR) with respect to every antenna pairs configuring STTD pairs to be transmittable from a transmitting end; feedbacking information indicating an antenna pair having the greatest SINR to the transmitting end; and the transmitting end’s performing a D-STTD transmission through the antenna pair determined by the feedbacked information. A method for transmitting a signal in accordance with another embodiment of the present invention comprises the steps of: a receiving end’s feedbacking information of an antenna pair and/or an eigenvector (weight vector) of a channel matrix with respect to transmit antennas included in the space-time multiplexing (STTD) pair of transmitting end; and the transmitting end’s forming beam by multiplexing a symbol with respect to each STTD pair by the eigenvector, and thereafter transmitting the beam through each transmit antenna (in case of using two antennas) or a transmit antenna pair (in case of using more than four antennas) determined by the information of the antenna pair.
    • 公开了一种使用多个发射/接收天线在移动通信系统中发送信号的方法。 根据本发明的实施例的用于发送信号的方法包括以下步骤:接收端相对于构成可从发送端发送的STTD对的每个天线对来计算信噪比(SINR); 指示具有最大SINR的天线对的反馈信息发送到发送端; 并且发送端通过由所反馈的信息确定的天线对执行D-STTD传输。 根据本发明的另一实施例的用于发送信号的方法包括以下步骤:接收端对天线对的反馈信息和/或信道矩阵的特征向量(权重向量)相对于包括在 空时复用(STTD)发送端对; 和发射端的形成波束,通过特征向量将每个STTD对的符号多路复用,然后通过每个发送天线(在使用两个天线的情况下)或发送天线对(在使用四个以上的情况下发送) 天线)由天线对的信息确定。
