Abstract: The present disclosure is related to a 5th generation (5G) or pre-5G communication system to provide higher data rates than a 4th generation (4G) communication system such as long term evolution (LTE). A method for adjusting a receive beam gain by a user equipment (UE) in a wireless communication system is provided. The method includes estimating a received signal quality value based on a reference signal received from a base station (BS), transmitting information about the estimated received signal quality value to the BS, comparing the received signal quality value with a minimum received signal quality value required for successful reception of data from the BS, and adjusting a receive beam gain to be used for data reception by turning on/off a radio frequency (RF) chain formed for each of antennas included in the UE based on a result of the comparison.
