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.
