Abstract: A method for a base station processing an in-band emission interference signal caused when the base station operating in a Full Duplex Radio (FDR) mode transceives signals using a Frequency Division Multiplexing (FDM) manner includes transmitting a downlink signal in a flexible downlink duration of an uplink band; and processing the in-band emission interference signal caused by transmission of the downlink signal in an uplink duration of the uplink band, wherein the processing of the in-band emission interference signal is performed by puncturing a corresponding resource of the uplink duration, wherein the resource on the downlink signal is transmitted is mirrored to the corresponding resource of the uplink duration from a Direct Current (DC) subcarrier as a reference.

Abstract: A method of transmitting uplink control information (UCI) by a user equipment in a wireless communication system, includes the steps of receiving downlink control information (DCI) indicating a transmission time of the UCI through a prescribed frequency band in a first subframe, receiving a downlink data based on the DCI, and transmitting UCI associated with the downlink data in a second subframe based on the indicated transmission time of the UCI. In this case, the prescribed frequency band on which the DCI is transmitted is configured by a plurality of DCCUs (downlink control channel units) for transmitting the DCI, and the UCI may be transmitted on an UCCU (uplink control channel unit) in the second subframe, a frequency band of the first UCCU being same as a frequency band corresponding to a DCCU of a lowest frequency among the plurality of DCCUs.
