The disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). A feedback transmission method for a receiving device in a multiple input multiple output system according to one embodiment comprises: a step of measuring channel state information; a first quantization step of quantizing the channel state information using a first codebook; a second quantization step of quantizing the channel state information using second and third codebooks which are different from the first codebook; and a step of feeding back the channel state information on the basis of a selection result of one of the first and second quantization steps.
