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 cancelling a self-interference (SI) signal in a communication system supporting a full-duplex scheme is provided. The method includes estimating an SI channel, performing a pre-filtering operation on a transmission signal based on the estimated SI channel, generating copied-SI signals based on the estimated SI channel, and cancelling an SI signal based on the copied-SI signals, wherein the pre-filtering operation includes an operation for decreasing a number of SI signals.

Abstract: The present invention relates to a 5th-generation (5G) or pre-5G communication system provided for supporting higher data transmission rates than 4th-generation (4G) communication system such as long term evolution (LTE). The present invention relates to a method in which an access point (AP) operates a full-duplex scheme in a communication system supporting a beam-forming scheme, the method comprising the steps of: generating a magnetic interference intensity table according to transmitted beam patterns and received beam patterns; determining, by the AP, a transmitted beam pattern and a received beam pattern for all stations (STAs) on the basis of channel measurement feedback information received from the stations, which provide service, and the electromagnetic-interference intensity table; and performing a communication operation with each of the stations on the basis of the determined transmitted beam pattern and received beam pattern.

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.
