A terminal transmits uplink data via a plurality of antennas and through a Physical Uplink Shared Channel (PUSCH), and receives an ACK/NACK (Acknowledgement/Non-Acknowledgement) signal indicating whether or not the uplink data has been received, the signal being received via the plurality of antennas and through a PHICH (Physical Hybrid-ARQ Indicator Channel) which corresponds to the PUSCH.

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.
