    Abstract: A method and apparatus for transmitting and receiving codebook-based channel state information in a wireless communication system are disclosed. A method of performing CSI report by a UE in a wireless communication system according to an embodiment of the present disclosure may comprise: receiving, from a base station, configuration information on the channel state information report; receiving, from the base station, at least one channel state information-reference signal (CSI-RS) based on the configuration information; and transmitting, to the base station, CSI calculated based on the at least one CSI-RS and priority-related information for omission of the corresponding CSI. Here, the priority-related information may be determined based on strongest coefficient information related to the corresponding CSI.

    Abstract: Disclosed are a method and device for transmitting and receiving an uplink in a wireless communication system. A method by which a terminal performs uplink transmission in a wireless communication system according to one embodiment of the present disclosure comprises the steps of: receiving, from a base station, first configuration information related to mapping between one or more uplink reference signals (UL RS) and one or more downlink (DL) RS; receiving, from the base station, second configuration information related to a plurality of spatial parameter candidates for uplink transmission; and performing uplink transmission in N (N ≥ 1) transmission opportunities (TO) on the basis of at least one among N uplink default spatial parameters and N pathloss reference signals (PL RS). The N uplink default spatial parameters are respectively associated with the N TOs. The N PL RSs are respectively associated with the N TOs. The default uplink spatial parameter for a specific TO among the N TOs may be: one spatial parameter, specified by a predefined rule, among the plurality of spatial parameter candidates based on the second configuration information; or a UL RS mapped to the one spatial parameter on the basis of the first configuration information.

    Abstract: The present disclosure provides a method for reporting channel state information in a wireless communication system, and an apparatus therefor. Specifically, a method for reporting channel state information (CSI) by a terminal (user equipment, UE) in a wireless communication system comprises the steps of: receiving CSI-related configuration information from a base station (BS); receiving a reference signal from the base station; calculating CSI on the basis of the reference signal; and transmitting, to the base station, uplink control information (UCI) for reporting of the CSI, wherein the CSI is calculated based on a codebook, and the CSI includes first information and second information selected based on the first information.

    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.
