Abstract: A method for transmitting and receiving, by a user equipment (UE), a phase noise compensation reference signal (PCRS) in a wireless communication system is disclosed. The method includes receiving, from a base station, control information related to a transmission of a downlink data, the control information including at least one of a precoding scheme related to the downlink data, a number of transmission ranks, or a modulation and coding scheme (MCS) level; checking a transmission location of a demodulation reference signal (DM-RS) for demodulating the downlink data based on the received control information; and receiving, from the base station, the PCRS on at least one symbol after a transmission symbol of the DM-RS considering the checked transmission location of the DM-RS.

Abstract: A method of transmitting, by a terminal, a phase noise compensation reference signal in a wireless communication system is discussed. The method includes determining a frequency resource and a time resource of a demodulation reference signal (DM-RS); mapping the phase noise compensation reference signal to a frequency resource and a time resource based on the determined frequency resource and the time resource of the DM-RS; and transmitting, to a base station, the phase noise compensation reference signal on the mapped frequency resource and the time resource of the phase compensation reference signal. Further, a location of a phase noise compensation reference signal symbol in the time resource is determined based on a location of a DM-RS symbol in the time resource of the DM-RS.

Abstract: A method for transmitting information data by using a Reed-Muller coding scheme in a wireless communication system is disclosed. The method includes configuring a number of resource elements for transmitting the information data; dividing the information data to first information data and second information data if a bit size O of the information data is equal to or larger than a predetermined number; applying RM coding on each of the first information data and the second information data; concatenating the coded first information data and the coded second information data, and transmitting the concatenated data by using the predetermined number of resource elements, wherein a minimum value Q′min for the number of resource elements is defined by a sum of a minimum value Q′min_1 for the number of resource elements corresponding to the first information data and a minimum value Q′min_2 for the number of resource elements corresponding to the second information data.

Abstract: The present invention relates to methods for interference cancellation between terminals in a full-duplex radio (FDR) system and apparatuses supporting the same. A method for cancelling interference between terminals in a wireless access system supporting a full-duplex radio (FDR) system, as an aspect of the present invention, may comprise the steps of: receiving, by a first terminal, reference signal information including information for configuring an interference reference signal from a base station; receiving the interference reference signal from a second terminal; obtaining, by the first terminal, interference channel information with regard to an interference channel between the first terminal and the second terminal on the basis of the interference reference signal; and transmitting by beamforming uplink data to the base station on the basis of the interference channel information by the first terminal. In this case, the first terminal is supported by the FDR system and the second terminal supports the half-duplex radio (HDR) system, and a resource area transmitting uplink data by the first terminal can be configured to match a resource area receiving downlink data by the second terminal.
