Device and method for transmitting and receiving feedback information in wireless communication system
Disclosed is a 5th generation (5G) or pre-5G communication system to be provided for supporting a data transmission rate higher than that of a 4th generation (4G) communication system such as long term evolution (LTE). Examples of the present invention provide a beam selection and feedback device and method for minimizing complexity and overhead without performance deterioration in a beamforming MIMO wireless communication system. According to one example of the present invention, an apparatus of a receiving device in a wireless communication system comprises: a transceiver; and at least one processor, wherein the at least one processor is configured to: select at least one beam pair from among a plurality of transmission/reception beam pairs, and control the transceiver to transmit feedback information including indication information indicating whether the at least one beam pair is identical to a beam pair selected in a previous beamforming procedure.
