Method for operating terminal in wireless communication system, and device using same method

A user equipment (UE) comprising:

• at least one transceiver;
• at least one memory;
• and
• at least one processor operably connectable to the at least one transceiver and the at least one memory,
• wherein the at least one memory stores instructions that, based on being executed by the at least one processor, cause the at least one processor to perform operations comprising:
• performing a random access procedure with a base station in at least one of subband full duplex (SBFD) symbols and non-SBFD symbols,
• wherein the random access procedure includes:
• transmitting a preamble on a physical random access channel (PRACH) to the base station,
• receiving a random access response (RAR) from the base station,
• performing a scheduled transmission to the base station using scheduling information in the RAR, and
• receiving a contention resolution message from the base station;
• reporting switching time information to the base station,
• wherein the switching time information informs the base station of a required switching time required for the UE to switch between an SBFD symbol and a non-SBFD symbol;
• and
• receiving configuration information from the base station,
• wherein the configuration information informs the UE of a configured switching time, wherein the UE skips transmission and reception with the base station during the configured switching time, and
• wherein the configured switching time is configured in a form of an index for a specific value among candidate values for a plurality of switching times.
