Abstract: Disclosed is a method for reporting channel quality information by a terminal to a base station in a wireless communication system to which hybrid beamforming is applied. Particularly, the method comprises the steps of: obtaining information associated with a first precoder for first beamforming from among hybrid beamforming; calculating information associated with a second precoder for second beamforming by receiving, from the base station, a reference signal to which the first beamforming is applied; calculating channel quality information by assuming that a pre-compensation precoder and the second precoder are applied; and reporting the channel quality information to the base station.

Abstract: A method for receiving control information for a reference signal related to phase noise estimation by a user equipment (UE), the method including receiving control information indicating whether the reference signal related to the phase noise estimation is transmitted; and when the control information indicates that the reference signal is transmitted, receiving the reference signal based on the control information. When a size of a traffic resource block (RB) for the UE is greater than a predetermined value, the control information indicates the reference signal is transmitted.

Abstract: The present invention relates to a method for efficiently supporting vehicle communication in a next-generation radio communication system, and a device therefor. To this end, a user equipment (UE) provides, to a central unit (CU) of the UE, primary channel state information measured by each of a plurality of antenna units that are disposed in distributed locations of the UE; determines any one of a plurality of receiving modes by considering the combined gain of the primary channel state information in the CU; determines a secondary channel state information according to the determined receiving mode; and reports, through a transceiver of the UE to the network, information indicative of the determined receiving mode and the determined secondary channel state information.

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: In the present invention, provided is a method for performing handover, by a first terminal, in an inter-vehicle communication system. Here, the method for performing handover, by the first terminal, may comprise the steps of: receiving information on a first bias value from a base station; receiving information on a second bias value from a second terminal; and performing handover on the basis of the first bias value and the second bias value. Here, the first terminal and the second terminal are configured in the same terminal group, the first bias value is a bias value for the terminal group, and the second bias value may be a bias value for the first terminal.

Abstract: Disclosed is a CFO estimation method, which generates a first function defined by a received signal of two sequential OFDM symbols for a specific subcarrier, generates a second function defined on the basis of signs and magnitudes of a real number part and an imaginary number part of the first function, repeats the steps of generating the first function and the second function for all of a subcarrier set, and determines, as a residual CFO, a phase of a third function obtained by adding up the results of the repetition.
