A method of receiving a downlink signal by a user equipment , UE, in a wireless communication system, the method comprising: receiving a configuration for a channel state information-reference signal, CSI-RS, resource; receiving slot format-related information, SFI, through a group common-physical downlink control channel, GC-PDCCH; and receiving downlink control information, DCI, the DCI scheduling an uplink signal or a downlink signal in a corresponding resource, characterized in that , the UE receives a CSI-RS in the CSI-RS resource or deactivates the reception of the CSI-RS in the CSI-RS resource, according to the SFI received through the GC-PDCCH, the SFI indicates whether each of a plurality of resources included in a slot is a downlink, DL, type of resource, an uplink, UL, type of resource, or a third type of resource for which DL or UL is not determined, if the SFI of the GC-PDCCH configures any one of the UL type or the third type to the CSI-RS resource, the UE deactivates the reception of the CSI-RS scheduled in the CSI-RS resource, if the corresponding resource in which the uplink signal or the downlink is scheduled, has been indicated as the third type by the SFI of the GC-PDCCH, the UE overrides the third type being configured in the corresponding resource by the SFI of the GC-PDCCH and transmits the uplink signal or receives the downlink signal on the corresponding resource based on the DCI, and if the corresponding resource in which the uplink signal or the downlink is scheduled, has been indicated as the DL type or the UL type by the SFI of the GC-PDCCH, the UE does not override the DL type or the UL type being configured in the corresponding resource by the SFI of the GC-PDCCH based on the DCI. receiving a configuration for a channel state information-reference signal, CSI-RS, resource; receiving slot format-related information, SFI, through a group common-physical downlink control channel, GC-PDCCH; and receiving downlink control information, DCI, the DCI scheduling an uplink signal or a downlink signal in a corresponding resource, characterized in that , the UE receives a CSI-RS in the CSI-RS resource or deactivates the reception of the CSI-RS in the CSI-RS resource, according to the SFI received through the GC-PDCCH, the SFI indicates whether each of a plurality of resources included in a slot is a downlink, DL, type of resource, an uplink, UL, type of resource, or a third type of resource for which DL or UL is not determined, if the SFI of the GC-PDCCH configures any one of the UL type or the third type to the CSI-RS resource, the UE deactivates the reception of the CSI-RS scheduled in the CSI-RS resource, if the corresponding resource in which the uplink signal or the downlink is scheduled, has been indicated as the third type by the SFI of the GC-PDCCH, the UE overrides the third type being configured in the corresponding resource by the SFI of the GC-PDCCH and transmits the uplink signal or receives the downlink signal on the corresponding resource based on the DCI, and if the corresponding resource in which the uplink signal or the downlink is scheduled, has been indicated as the DL type or the UL type by the SFI of the GC-PDCCH, the UE does not override the DL type or the UL type being configured in the corresponding resource by the SFI of the GC-PDCCH based on the DCI. <EOS>
