Abstract: Disclosed is a method for setting a resource for Full Duplex Radio (FDR) Communication by a node in an FDR communication environment. According to the method, resources for the FDR communication can be selected in consideration of channel information of the nodes performing the FDR communication to obtain an improved achievable sum rate compared to Half Duplex Radio (HDR) communication schemes and to acquire diversity effects.

Abstract: A method of transmitting a power control factor by a device performing self-interference cancellation (SIC) in a wireless communication system using full-duplex radio (FDR) according to the present invention includes: transmitting, to a user equipment (UE), a first indicator indicating a power control for purpose of reducing an order to be considered as nonlinear components of a self-interference signal; and receiving, from the UE, a second indicator indicating whether the power control for the purpose of reducing the order to be considered as the nonlinear components of the self-interference signal is accepted or not in response to the first indicator.

Abstract: A method for selecting, by a base station, HD mode or FD mode in a wireless communication system supporting an FDR scheme may comprise: a step of receiving, from a second terminal which receives interference from a first terminal, a value related to the signal to noise ratio (SNR) of the second terminal and a value related to the signal-to-interference-plus-noise ratio (SINR) of the second terminal; a step of measuring the SNR value and the SINR value of the base station; a step of calculating the channel capacity ratio between the HD mode and the FD mode by using the received value related to the SNR of the second terminal, the received value related to the SINR of the second terminal, the measured SNR value of the base station, and the measured SINR value of the base station; and a step of selecting either mode on the basis of the calculated channel capacity ratio between the HD mode and the FD mode.

Abstract: A method of demodulating a channel by a user equipment in a wireless communication system, include the steps of receiving information including a total power value of reference signals (RSs), a power difference value between power of a first RS for control information and a power of a second RS for data among the RSs, a port number of an additional RS, a cyclic shift (CS) value of the additional RS, and a power value of the additional RS and a power difference value between second RSs for the control information, performing channel estimation on a first channel on which the additional RS is received and a second channel received from a port identical to the port number of the additional RS and the second channel on which the first RS to which a CS value different from the CS value of the additional RS is applied is received, obtaining a power difference value between the power of the additional RS and the power of the first RS based on the channel estimation of the first and the second channels, and determining a number of rank of the second RS based on the total power value of the RSs, the power value of the additional RS, a power difference value between the power of the first RS and the power of the second RS, the obtained power difference value between the power of the additional RS and the power of the first RS, and the power difference value between the power of the second RSs.
