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.

Abstract: In an aspect of the present invention, provided is a method for receiving an uplink signal by a base station (BS) in a wireless communication system where a reference signal is not used, including: obtaining information bits by demodulating and decoding a signal of a first user equipment (UE) that is modulated through a differential modulation scheme; estimating a channel between the first UE and the BS using the information bits; and performing successive interference cancellation (SIC) using the signal of the first UE restored through the channel estimation results and the information bits. In this case, the BS may estimate the channel between the first UE and the BS by assuming that an Nth modulation symbol among modulation symbols of the information bits modulated through the differential modulation scheme is fixed to a predetermined constellation point.

Abstract: A method for transmitting an uplink signal by a user equipment on a carrier where multiple subbands, each having different subcarrier spacing, are multiplexed may include: generating M modulated symbols by modulating uplink data; repeating the M modulated symbols in both upper and lower frequency blocks, which are adjacent to a predetermined frequency block for the M modulated symbols and have the same size as that of the predetermined frequency block; obtaining a tapered pulse by multiplying a total of 3M modulated symbols, which are a result of the repetition, and a total of 3M windowing weight values in an element-wise manner; and transmitting the tapered pulse after performing an inverse Fourier transform, wherein the user equipment can restrict leakage power to subbands unsynchronized with its operating subband to be equal to or lower than a threshold by adjusting a tapering length of the tapered pulse.
