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: The present invention relates to a wireless communication system. In detail, the present invention is a method for transmitting a scheduling request (SR) by a user equipment (UE) in a wireless communication system includes: receiving information on a resource for the scheduling request (SR) from a base station (BS); transmitting the scheduling request (SR) using the scheduling request (SR) resource transmitted over a control channel; and transmitting a first buffer status report (BSR) using uplink (UL) contention-based resources transmitted over a data channel. The UL contention-based resources are determined based on at least one of the resource for the scheduling request (SR) or an identifier (ID) of the UE.

Abstract: A method for removing a self-interference signal by a device supporting an FDR mode can further comprise the steps of: transmitting a signal to a counterpart node in a predetermined time interval; generating, in an RF stage of the device, a residual self-interference signal after removal of an analog self-interference signal with respect to the signal and then storing same; and receiving from the counterpart node a NACK signal with respect to the transmission of the signal; retransmitting the signal to the counterpart node; and, if decoding of the signal which has been received in the predetermined time interval is successful, using only a part of the stored residual self-interference signal when removing a digital self-interference signal on the basis of the retransmission.

Abstract: The present invention relates to a wireless access system supporting a millimeter wave (mmWave), and provides methods for performing a fast fallback in order to avoid a link disconnection and devices supporting the same. As an embodiment of the present invention, a method for performing a fast fallback by a terminal in a wireless access system supporting a millimeter wave (mmWave) may comprise the steps of: establishing radio resource control (RRC) connections with a mmWave base station and a legacy base station, respectively; receiving downlink data transmitted from the mmWave base station; receiving, from the legacy base station, resource-related information associated with a resource to be allocated for a fast fallback; detecting whether a non-light of sight (NLoS) transition occurs in a mmWave link with the mmWave base station; and when the NLoS transition occurs, transmitting a fallback request message to the legacy base station in order to perform the fast fallback.
