Abstract: A method is provided for receiving aperiodic channel state information (CSI). A base station (BS) transmits, to a user equipment (UE), an uplink downlink control information (DCI) format. The BS receives, from the UE, aperiodic CSI through a physical uplink shared channel (PUSCH) if the BS triggers an aperiodic CSI report using a CSI request field included in the uplink DCI format. The CSI request field is either a 1-bit field or a multi-bit field. When the UE is configured with only one cell, the 1-bit field is included in the uplink DCI. When the UE is configured with more than one channel state information-reference signal (CSI-RS), the multi-bit field is included in the uplink DCI.

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.
