Abstract: A method of a UE for canceling a self-interference (SI) signal in a wireless communication system is disclosed. The method comprises the steps of generating a signal related to transmission data by means of a UE operating in a full duplex radio (FDR) mode; transmitting the signal related to transmission data; receiving a signal related to reception data by means of the UE; and canceling the SI signal on the basis of the signal related to transmission data and the signal related to reception data. In this case, a cancellation signal is further generated from the signal related to transmission data on the basis of a previously set value of a power amplifier (PA), and the SI signal is canceled by further reflecting the generated cancellation signal.

Abstract: The present document relates to a wireless frame structure for implementing a low-delay communication in a next generation wireless communication system, and a communication method and apparatus using same. To this end, a terminal receives downlink data from a base station through a data area of a wireless frame, and sends, to the base station, an acknowledgement signal with respect to the downlink data using an uplink control channel area of the wireless frame. Every sub-frame of the wireless frame includes a downlink control channel area and the uplink control channel area, wherein the downlink control channel area is located within a first certain number of symbol areas starting from the start point of the sub-frame, and the uplink control channel area is located within a second certain number of symbol areas starting from the end point of the sub-frame.

Abstract: A method and a device for transmitting control information to be used in a terminal are provided. Specifically, an asynchronous level of a terminal supporting an asynchronous transmission mode is measured by using a signal received from the terminal. It is determined whether a measured value of the asynchronous level exceeds a threshold value, and if the asynchronous level is exceeded, a filter length and a CP length, which are to be used in the terminal, are changed. Information on the changed filter length and CP length is transmitted to the terminal. A sum of the filter length and the CP length is fixed, a characteristic of out-of-band emission improves when the filter becomes long in length, and interference occurring due to a multi-path delay can be prevented when the CP length becomes long.
