Abstract: The present specification provides a method for reporting channel state information (CSI) on the basis of priorities in a wireless communication system. More specifically, the method performed by a terminal comprises: a step of receiving, from a base station, downlink control information (DCI) including a reporting trigger for a plurality of CSIs of the same type; and a step of reporting a specific CSI determined on the basis of a predetermined rule among the plurality of CSIs if a time resource and a frequency resource for reporting among the plurality of CSIs are the same, wherein the specific CSI is a CSI that has priority among the plurality of CSIs on the basis of the predetermined rule.

Abstract: Disclosed herein is a method for receiving a user equipment-specific reference signal-based data signal by a user equipment in a wireless communication system. Particularly, the method comprises the steps of: receiving a control signal for the user equipment-specific reference signal-based data signal from an eNodeB; and receiving the user equipment-specific reference signal-based data signal on the basis of the control signal, wherein the control signal includes information on an antenna port for a channel status information-reference signal, the antenna port being assumed to be quasi-co-located (QCL) with an antenna port for the user equipment-specific reference signal, and the channel status information-reference signal excludes an aperiodic channel status information-reference signal.

Abstract: The present specification provides a method for measuring and reporting channel state information (CSI) in a wireless communication system and a device for same. More particularly, in a method for reporting channel state information in a wireless communication system, the method which is carried out by means of a base station can comprise the steps of: transmitting CSI report configuration information associated with a CSI report to a terminal, wherein the CSI report configuration information comprises information indicating a time offset for the CSI report; transmitting a channel state information reference signal (CSI-RS) to the terminal; transmitting control information, which is for triggering the CSI report, to the terminal; and receiving from the terminal the CSI report which is generated on the basis of the measurement with respect to the CSI-RS. Here, if the information indicating the time offset for the CSI report is configured in “0” value, the CSI-RS can be transmitted periodically or semi-continuously.
