    Abstract: Disclosed are a method for transmitting or receiving channel state information in a wireless communication system and a device therefor. Specifically, a method for transmitting channel state information (CSI) by a terminal in a wireless communication system may comprise the steps of: receiving, from a base station, the number of antenna ports specific to one or more channel state information-reference signal (CSI-RS) resources; receiving, by the terminal, a CSI-RS on the one or more antenna ports from the base station; when the number of one or more CSI-RS resource-specific antenna ports configured in the terminal is different from the number of antenna ports in reporting units of the CSI configured in the terminal, estimating a CSI-RS antenna port on the basis of the number of antenna ports in reporting units of the CSI configured in the terminal, and deriving the CSI on the basis of the CSI-RS; and reporting the CSI to the base station.

    Abstract: Disclosed is a method for receiving a downlink signal by a terminal in a wireless communication system. Specifically, the method comprises the steps of: receiving, from a network, information on at least two first-type reference signal port groups and information on at least two second-type reference signal port groups; and receiving, from at least two transmission points constituting the network, a downlink signal including at least two codewords by using the information on the at least two first-type reference signal port groups and the information on the at least two second-type reference signal port groups, wherein the at least two first-type reference signal port groups correspond to different transmission points and the at least two second-type reference signal port groups correspond to different codewords.

    Abstract: The present invention according to one embodiment comprises the steps of: receiving linear-combination (LC) code word-based channel state reporting configuration, which is expressed by parameters comprising an LC coefficient and a phase differential (co-phase) value between antenna groups having mutually different polarization characteristics; measuring a downlink reference signal for a channel state reporting in accordance with the received channel state reporting configuration; and transmitting, to a base station, the LC code book-based channel state report corresponding to the reference signal measurement, wherein the channel state reporting can only support a broadband reporting mode.

    Abstract: A method for receiving, by a user equipment (UE), a channel state information reference signal (CSI-RS) in a wireless communication system, includes receiving, from a base station, CSI-RS resource configuration information related to a numbering for a plurality of CSI-RS resources through a radio resource control (RRC) signaling, wherein the CSI-RS resource configuration information includes first CSI-RS configuration information and at least one second CSI-RS configuration information; and determining numbers for the plurality of CSI-RS resources based on the received CSI-RS resource configuration, wherein a specific CSI-RS resource among the plurality of CSI-RS resources corresponds to a value configured in the first CSI-RS configuration information, and at least one CSI-RS resource except the specific CSI-RS resource among the plurality of CSI-RS resources corresponds to a value configured in the second CSI-RS configuration information, and wherein the specific CSI-RS resource is a CSI-RS resource related to a lowest number among the plurality of CSI-RS resources.

    Abstract: The present disclosure provides a method for reporting channel state information (CSI) in a wireless communication system, and a device therefor. Specifically, the present invention provides a method for reporting CSI via a physical uplink shared channel (PUSCH) by a user equipment (UE) in a wireless communication system, the method comprising the steps of: receiving configuration information from a base station (BS), wherein the configuration information comprises (i) a CSI-related configuration and (ii) a configuration related to a transmission power control of the PUSCH; receiving a CSI-reference signal (CSI-RS) from the base station on the basis of the CSI-related configuration; calculating the CSI on the basis of the CSI-RS, wherein the CSI comprises information related with coefficients, elements of the information related with coefficients are classified into multiple groups on the basis of priority values thereof, and the priority values have an ascending sequence in which, with reference to a predefined particular index, a higher index and a lower index of frequency-domain indices related to the elements sequentially alternate; and on the basis of predetermined priorities of the multiple groups, transmitting a CSI report configured by omitting a portion of the multiple groups, to the base station via the PUSCH, wherein transmission power of the PUSCH is determined on the basis of the configuration information.
