1. A method performed by a receiving apparatus in a wireless communication system, the method comprising:
receiving reference signals from a transmitting apparatus;
estimating respective channel component values of the reference signals;
identifying whether at least one first reference channel component value which is equal to or greater than a first threshold is present among the channel component values of the reference signals;
interpolating the channel component values of the reference signals based on a deep learning-based channel estimation scheme in case that the at least one first reference channel component value is not present;
identifying whether at least one second reference channel component value which is equal to or greater than the first threshold is present among the interpolated channel component values of the reference signals;
selecting a first candidate beam based on the at least one second reference channel component value in case that the at least one second reference channel component value is present;
identifying whether a value of signal quality of the first candidate beam is equal to or greater than a second threshold; and
selecting the first candidate beam as a first final beam in case that the value of signal quality of the first candidate beam is equal to or greater than the second threshold.
