Abstract: The present 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 a long term evolution (LTE). A method for performing a beamforming operation in a wireless communication system supporting a full-duplex scheme includes acquiring reference information for allocating a resource, determining a user equipment (UE) combination of a transmission (Tx) UE and a reception (Rx) UE which is capable of sharing a resource from combinations of at least Tx UE and at least one Rx UE, based on the acquired reference information, and allocating a Tx antenna beam for the Tx UE of the UE combination and an Rx antenna beam for the Rx UE of the UE combination.

Abstract: Disclosed is a 5G or pre-5G communication system to be provided for supporting a data transmission rate higher than that of a 4G communication system such as LTE. A method for cancelling self-interference in a full-duplex communication system is provided. The method comprises the steps of: cancelling cancellable self-interference components through an analog interference cancellation circuit, and estimating a channel state of an uplink channel and a channel state of a downlink channel on the basis of remaining residual self-interference components; estimating a channel capacity for each of possible beam combinations on the basis of the estimated uplink channel state and downlink channel state; selecting the beam combination having the largest channel capacity from among the possible beam combinations; and cancelling self-interference from a received signal on the basis of the selected beam combination.
