Abstract: According to one embodiment of the present invention, a method by which a fixed base station adjusts inter-cell interference in a wireless communication system comprises the steps of: receiving channel state information-reference signal (CSI-RS) configurations on an access link of each moving cell connected to the fixed base station; determining the CSI-RS configuration on a backhaul link of a first moving cell among the moving cells on the basis of the CSI-RS configurations on the access link; and providing, to the first moving cell, the CSI-RS configuration on the determined backhaul link, wherein the CSI-RS configuration on the determined backhaul link is for measuring, by the backhaul link of the first moving cell, the interference received from an access link of a second moving cell among the moving cells.

Abstract: A method for transmitting information related to a sounding reference signal (SRS) transmission by a base station (BS) of a full duplex radio (FDR) mode in a wireless communication system includes: transmitting information related to a resource region to be used for the SRS transmission to a user equipment of the FDR mode within a resource region configured as an uplink (UL) idle interval; receiving a SRS through the resource region for the SRS transmission from the user equipment; performing an uplink (UL) channel estimation based on the received SRS; and performing a downlink (DL) channel estimation by applying a channel reciprocity characteristic to a result of the uplink (UL) channel estimation.
