    Abstract: The present invention provides a method for reporting channel status information (CSI) for downlink transmission to an eNode B (eNB) by a user equipment (UE) in a wireless communication system. Specifically, the method comprises the steps of: receiving a channel status information-reference signal (CSI-RS) from the eNB; calculating the CSI on the basis of the CSI-RS under the assumption that a dual-precoder including a first precoder and a second precoder is applied; and reporting the CSI to the eNB, wherein the step of calculating the CSI includes a step for assuming that at least one of the first precoder and the second precoder is cyclically employed from a predetermined precoder candidate set on the basis of a predetermined resource unit; and information associated with the at least one precoder and information associated with the predetermined precoder candidate set are provided from the eNB through radio resource control (RRC) layer signaling.

    Abstract: The present invention discloses a method for measuring a Synchronization Signal Block (SSB) by a terminal in a wireless communication system. In particular, the method according to the present invention may include: receiving a cell list including information of at least one first cell, first SSB transmission periodicity information for the at least one cell, and second SSB transmission periodicity information for a second cell that is not included in the cell list; measuring Reference Signal Received Power (RSRP) for an SSB of the at least one first cell based on a first SSB measurement window, which is set up by using the first SSB transmission periodicity information; and measuring RSRP for an SSB of the second cell based on a second SSB measurement window, which is set up by using the second SSB transmission periodicity information.
