Method and apparatus for supporting full duplex operation in wireless communication system

A method performed by a terminal in a wireless communication system, the method comprising:

• receiving, from a base station, information indicating an area of a full-duplex (FD) mode and an area of a half-duplex (HD) mode in a bandwidth part activated for the terminal;
• identifying at least one first resource for the area of the FD mode and at least one second resource for the area of the HD mode, among resources in the activated bandwidth part, based on the information;
• and
• performing a first communication operation on the at least one first resource and performing a second communication operation on the at least one second resource,
• wherein a self-interference cancellation gain obtained for the at least one first resource is less than a threshold and the self-interference cancellation gain obtained for the at least one second resource is greater than or equal to the threshold, and
• wherein a modulation and coding scheme (MCS) applied for the area of the FD mode is configured to be lower than an MCS applied for the area of the HD mode.

A base station in a wireless communication system, the base station comprising:

• a transceiver;
• and
• a controller configured to:
• identify a self-interference cancellation gain obtained based on a self-interference cancellation operation for resources in a bandwidth part activated for a terminal, the self-interference cancellation gain obtained for at least one first resource among the resources being less than a threshold and the self-interference cancellation gain obtained for at least one second resource among the resources being greater than or equal to the threshold,
• configure the at least one first resource as an area of a full-duplex (FD) mode and the at least one second resource as the area of a half-duplex (HD) mode,
• generate information indicating the area of the FD mode and the area of the HD mode;
• and
• control the transceiver to transmit, to the terminal, the information,
• wherein a modulation and coding scheme (MCS) applied for the area of the FD mode is configured to be lower than an MCS applied for the area of the HD mode.
