pmi selection method for the non-adaptive harq in a wireless communication system supporting multiple antennas

The following description is directed to a method for efficiently obtaining a terminal precoding information, and transmits an uplink signal by using this method in transmitting the uplink signal in a multiple antenna system. That is, set in as the terminal transmits an uplink signal, to receive a scheduling grant (Scheduling Grant) signal including a precoding matrix information available on an uplink signal transmitted from the base station to the terminal. This terminal can transmit by applying the precoding in the uplink signal using. However, it is possible to use a case, the precoding matrix information included in the scheduling signal received for the same HARQ process, a recently received do not receive a scheduling grant signal for the retransmission from the base station in the case of retransmitting the above-described signal.
