Method for performing communication in wireless communication system and device therefor

A user equipment (UE) comprising:

• a radio frequency (RF) transceiver;
• and
• a processor connected to the RF transceiver,
• wherein the processor controls the RF transceiver to receive time division duplexing (TDD) configuration information for configuring a downlink (DL) time duration and an uplink (UL) time duration within a time resource period, receive indication information specifying a first time duration related to a full-duplex operation of a base station (BS) within the time resource period, and perform communication with the BS based on the indication information and the TDD configuration information, and
• based on the indication information indicating only one of a start symbol, a last symbol, and a duration of the first time duration, the first time duration is specified by further considering a boundary of one of the UL time duration and the DL time duration.
