Abstract: A method for a device changing a RS mode, the device operating by a FDR scheme, comprises the steps of: deciding to change from a first RS mode to a second RS mode if a preset condition is satisfied; and transmitting information related to the decided second RS mode to a terminal, wherein the first RS mode and the second RS mode may be distinguished from each other by whether RSs which are added in order to channel estimate a non-linear component of a self-interference signal are transmitted or not.

Abstract: A method for stably operating an FDR mode by a terminal in a wireless communication system supporting the full-duplex radio (FDR) mode comprises the steps of: if a residual self-interference signal is changed to a predetermined threshold or higher in a terminal, transmitting information about the changed residual self-interference signal to a base station; and receiving from the base station a downlink signal on the basis of a modulation and coding scheme (MCS) level that corresponds to the information about the changed residual self-interference signal.

Abstract: A method for a FDR scheme-using communication device transmitting reference signals for estimating a channel of a non-linear self-interference signal comprises the step of transmitting, on a specific symbol of a corresponding subframe, reference signals for estimating the channel of the non-linear self-interference signal, wherein a sequence mapped to the reference signals is a sequence generated in a frequency domain by being discrete Fourier transform (DFT)-converted, and the generated sequence may be mapped, on the frequency domain, to a RE for the reference signals.

Abstract: A method and a device for performing communication by using a non-orthogonal code multiple access scheme in a wireless communication system are provided. Particularly, a terminal receives control information from a base station. The terminal modulates or demodulates a terminal-specific NCC on the basis of the control information. The terminal performs the non-orthogonal code multiple access scheme by using the terminal-specific NCC. The control information includes information on a codeword composed of a Grassmannian sequence. The codeword is included in a codebook predefined for the non-orthogonal code multiple access scheme. Each coefficient of the Grassmannian sequence is quantized on the basis of an M-quadrature amplitude modulation (M-QAM) constellation.

Abstract: A method for a base station processing an in-band emission interference signal caused when the base station operating in a Full Duplex Radio (FDR) mode transceives signals using a Frequency Division Multiplexing (FDM) manner includes transmitting a downlink signal in a flexible downlink duration of an uplink band; and processing the in-band emission interference signal caused by transmission of the downlink signal in an uplink duration of the uplink band, wherein the processing of the in-band emission interference signal is performed by puncturing a corresponding resource of the uplink duration, wherein the resource on the downlink signal is transmitted is mirrored to the corresponding resource of the uplink duration from a Direct Current (DC) subcarrier as a reference.
