    Abstract: Disclosed is a method for a terminal reporting channel status information (CSI) to a base station in a wireless communication system. The method comprises receiving, via an upper later, information associated with a single CSI process comprising a firs enhanced multiple input multiple output (eMIMO) type and a second eMIMO type; reporting, to a base station, a first CSI updated on the basis of a first channel status information-reference signal (CSI-RS) corresponding to the first eMIMO type received from a first subframe; and receiving, from the base station, a triggering message of a second CSI calculated on the basis of a second CSI-RS corresponding to the second eMIMO type from a second subframe.

    Abstract: The present specification provides a method for transmitting and receiving a signal by means of a beam in a wireless communication system. The method for a terminal for transmitting and receiving a signal by means of one or more beams according to the present specification may comprise the steps of: receiving sounding reference signal (SRS) resource configuration information for an SRS transmission from a base station, the SRS resource configuration information comprising configuration information indicating one or more previously configured timing advance values for one or more SRS resources; receiving, from the base station, control information indicating a particular SRS resource from among the one or more SRS resources; and transmitting an uplink signal at the configured temporal uplink transmission point using the timing advance value corresponding to the particular SRS resource.

    Abstract: A method for measuring and reporting channel state information (CSI) in a wireless communication system and a device therefor. Specifically, a method for reporting, by a user equipment, channel state information (CSI) in a wireless communication system includes: receiving CSI reporting setting information related with CSI reporting; receiving one or more channel state information (CSI)-reference signals (CSI-RSs); performing the CSI reporting by using a measurement value estimated by at least one specific CSI-RS among the one or more CSI-RSs, in which the at least one specific CSI-RS may be determined based on gap information for configuring a measurement interval for estimating the measurement value and a performing timing of the CSI reporting.

    Abstract: Disclosed in the present invention is a method by which a terminal reports channel status information (CSI) to a base station in a wireless communication system. The method comprises the steps of: receiving, through an upper layer, information on one CSI process having a first enhanced multiple input multiple output (eMIMO) type and a second eMIMO type; receiving a first channel status information-reference signal (CSI-RS) corresponding to the first eMIMO type; periodically reporting, to the base station, first CSI measured on the basis of the first CSI-RS; receiving a second CSI-RS, which corresponds to the second eMIMO type, beamformed on the basis of the first CSI; and periodically reporting, to the base station, second CSI measured on the basis of the second CSI-RS, wherein a priority of the first CSI is set to be equal to a priority of a CSI-RS resource indicator (CRI).
