The method includes determining a phase shift based precoding matrix phase shifted at a predetermined phase angle, initially transmitting each sub-carrier symbol to a receiver in a packet unit by using the phase shift based precoding matrix, reconstructing the phase shift based precoding matrix to reduce a spatial multiplexing rate if a negative reception acknowledgement (NACK) is received from the receiver, and retransmitting the initially transmitted sub-carrier symbol by using the reconstructed phase shift based precoding matrix or by changing the phase shift based precoding matrix using offset information fed back from the receiver or random offset information.

Abstract: A method of transmitting control information includes dividing frequency bandwidth into ranges to which the same PMI (precoding matrix index) is applied, obtaining multiple antenna information by the range to which the same PMI is applied and transmitting the multiple antenna information. Since multiple antenna information is transmitted by the unit of a range to which the same PMI is applied, radio resources allocated for transmitting the multiple antenna information may be reduced, thereby enhancing data transmission efficiency.
Abstract translation: 发送控制信息的方法包括将频带宽度划分到应用了相同PMI（预编码矩阵索引）的范围内，通过应用相同PMI的范围获得多个天线信息并发送多个天线信息。 由于多个天线信息通过应用相同PMI的范围的单位发送，所以可以减少分配用于发送多个天线信息的无线电资源，从而提高数据传输效率。
