Abstract: A method for transmitting an uplink signal at a User Equipment (UE) in a wireless communication system includes receiving, from a Base Station (BS), an uplink scheduling grant for multi-antenna transmission; transmitting the uplink signal precoded using precoding information included in the received uplink scheduling grant to the BS; and retransmitting the uplink signal to the BS according to Acknowledgment/Negative Acknowledgment (ACK/NACK) corresponding to the transmitted uplink signal. The retransmitted uplink signal is precoded using precoding information included in a most recent uplink scheduling grant or a predetermined precoding matrix if an uplink scheduling grant for the retransmission is not received from the BS.
