Abstract: A method for operating a user equipment in a wireless communication is provided as an embodiment of the present invention. The method may include: receiving modulation and coding scheme (MCS) information for each of two or more codewords from a base station (BS); determining a demodulation reference signal (DMRS) antenna port to which a phase tracking reference signal (PTRS) antenna port is mapped based on the MCS information; and receiving a PTRS based on the DMRS antenna port, wherein a DMRS antenna port with the lowest index among one or more DMRS antenna ports included in a codeword with the highest MCS among the two or more codewords may be determined as the DMRS antenna port.

Abstract: A method for a base station to transmit a signal allowing a terminal to remove phase noise in an mmWave communication system, according to an embodiment of the present specification, may be provided. Here, the method for transmitting a signal for removing phase noise comprises: a step of generating a phase tracking reference signal (PTRS) and a first RS; a step of assigning the PTRS and the first RS to a resource block; and a step of transmitting the assigned PTRS and first RS, wherein the step of assigning the PTRS and the first RS includes a step of changing a frequency location of the PTRS if the PTRS and the first RS collide in the resource block, wherein the changed PTRS frequency location may be changed to a frequency location, across frequencies on which a predetermined demodulation reference signal (DMRS) port, associated with the PTRS, in a DMRS port group is located, which is closest to the existing PTRS frequency location and avoids collision with the first RS.

Abstract: Systems and techniques for reporting channel state information (CSI) in a wireless communication system and a device therefor. Particularly, a method for reporting channel state information (CSI) of a terminal in a wireless communication system can include the steps of: measuring a CSI reference signal (CSI-RS) transmitted by means of multi-panels from a base station; and reporting CSI, which is generated on the basis of the CSI-RS measurement, to the base station. If the terminal receives, from the base station, configuration of a CSI report excluding a matrix index for phase calibration between panels, the CSI includes only a first matrix index, for wide-band (WB) panel compensation, and a second matrix index, for subband (SB) panel compensation, and can be calculated by means of the first matrix index, the second matrix index and a particular matrix index associated with the phase calibration between the panels.
