Abstract: The present invention relates to a wireless access system supporting a full duplex radio (FDR) transmission environment. A method for receiving feedback information by a base station in a wireless access system supporting FDR comprises the steps of: transmitting, to a terminal, frame configuration information of terminal-specific time division multiplexing (TDD); and receiving, from the terminal, feedback information in an uplink (UL) subframe according to the frame configuration information, wherein the frame configuration information can determine the location of the UL subframe in which feedback information for each DL subframe is to be transmitted, on the basis of the value obtained by dividing the number of downlink (DL) subframes by the number of UL subframes in a wireless frame.

Abstract: The present invention provides a method for defining, and for transmitting, a new uplink reference signal and devices supporting the method. In one embodiment of the present invention, a method in which a terminal transmits a millimetre wave reference signal (mW-RS) in a millimetre-wave (mmWave)-supporting wireless access system comprises the steps of: receiving a downlink reference signal in a predetermined number of sub-frames, and measuring two or more received power levels; determining whether to transmit an mW-RS, based on the value(s) of the difference(s) between the two or more received power levels; and transmitting the mW-RS if it has been decided to transmit an mW-RS. Here, the mW-RS is transmitted in order to measure whether the state of a wireless channel has transitioned between an LoS (Light of Sight) state and a NLoS (Non-LoS) state.

Abstract: In this disclosure, methods and apparatus for managing interference are disclosed. In one example, the first station receives the first signal from the base station. The first station acquires information on a specific processing scheme of a second station for processing the first signal to be transmitted to a third station at the second station. The first station receives a second signal from the base station while the second station transmits the first signal to the third station. Here, since the first station has knowledge on the first signal and the information on the specific processing scheme, it can manage interference caused by the first signal from the second station.
