Abstract: A method is provided for transmitting a demodulation reference signal (DMRS) by a user equipment (UE) in a wireless communication system. The UE receives a cyclic shift field in an uplink scheduling assignment from a base station, allocates a first cyclic shift value of a first DMRS for a first layer and a second cyclic shift value of a second DMRS for a second layer, based on the cyclic shift field, and transmits the first DMRS and the second DMRS to the base station.

Abstract: A method for correcting errors in a multiple antenna system based on a plurality of sub-carriers and a transmitting/receiving apparatus supporting the same are disclosed. 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.
