1. A method performed by a user equipment (UE) in a wireless communication system, the method comprising:
performing communication with a base station;
transmitting, to the base station, uplink control information (UCI);
receiving, from the base station, downlink control information (DCI);
transmitting, to the base station, a first message for requesting a uplink resource;
receiving, from the base station, a second message for allocating the uplink resource;
transmitting at least one signal on the uplink resource; and
performing calibration of a circuit for analog self-interference cancellation (SIC) based on the at least one signal,
wherein the UCI includes at least one of first information related to performance of the analog SIC, second information related to performance of total SIC, third information related to a maximum number of transmit ports or fourth information related to a maximum number of receive ports,
wherein the first information includes a plurality of values related to the performance of the analog SIC for a plurality of pairs of a transmit port and a receive port,
wherein the first message includes information related to a required minimum time length for the calibration, and
wherein the second message includes an indication informing that the uplink resource comprises a resource for the calibration.
