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.

Abstract: A method for channel measurement is provided when a mobile terminal is configured with a primary component carrier and a secondary component carrier. The mobile terminal receives configuration information for channel measurement in the secondary component carrier from a base station. The mobile terminal derives the channel measurement in the secondary component carrier based on a channel state information reference signal (CSI-RS) when the configuration information includes a first indicator indicating that CSI-RS is used for the channel measurement in the secondary component carrier, or deriving the channel measurement in the secondary component carrier based on a cell-specific reference signal (CRS) when the configuration information does not include the first indicator.

Abstract: A method for a transmitting side transmitting a signal for low transmission latency in a wireless communication system, according to one embodiment of the present invention, comprises the steps of: mapping a signal to at least one subframe; and the transmitting side transmitting the signal to a receiving side. Here, the at least one subframe is a legacy subframe comprising L number of orthogonal frequency division multiplexing (OFDM) symbols, or an advanced subframe comprising N number of OFDM symbols, wherein the advanced subframe may be transmitted twice or more times within the transmission period of the legacy subframe.

Abstract: Disclosed herein are a method and apparatus for requesting scheduling in a wireless communication system. More specifically, a method of requesting scheduling for transmitting uplink data in a wireless communication system may include transmitting, by user equipment (UE), a Scheduling Request (SR) of an SR type selected from multiple SR types to an eNB, receiving, by the UE, an uplink grant determined according to the selected SR type from the eNB, and transmitting, by the UE, uplink data to the eNB through a physical uplink shared channel (PUSCH) resource allocated by the uplink grant.
