Abstract: The present disclosure relates 5G or pre-5G communication systems for supporting higher data transmission rate than those by LTE or other post-4G communication systems. According to the present disclosure, a method for operating a beamformed reference signal by a base station and terminal in a communication system, and the terminal, are provided. The method includes transmitting, to a terminal, control information indicating whether a first codebook is used for generating feedback information on a downlink reference signal. The first codebook is used if generating feedback information on the beamformed reference signal and is generated based on a number of antenna ports and a number of ranks.

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.

Abstract: The present disclosure relates to a 5G or pre-5G communication system to be provided for supporting a data rate higher than that of a 4G communication system, such as LTE, and subsequent communication systems. The present disclosure relates to a method for transmitting a reference signal (RS) in a wireless communication system, comprising the steps of: configuring a transmission resource by including at least one resource block (RB), which does not map the RS, between two RBs, which map the RS, in a first subframe; transmitting a first message for directing an RB offset indicating a gap between the two RBs, which map the RS, and locations of the RBs, which map the RS; and transmitting the RS through the configured transmission resource.
