Method for transmitting or receiving data in wireless communication system supporting half-duplex frequency division duplexing, and device therefor

A method of receiving, by a user equipment, synchronization signal block (SSB) in a wireless communication system supporting a frequency division duplexing (FDD), the method comprising:

• receiving, from a base station, configuration information through higher-layer signaling;
• and
• receiving, from the base station, the SSB based on the configuration information,
• wherein an uplink transmission including at least one symbol within a minimum time for switching before the first symbol of the SSB and/or an uplink transmission including at least one symbol within a minimum time for switching after the last symbol of the SSB is not performed.

A user equipment configured to receive synchronization signal block (SSB) in a wireless communication system supporting a frequency division duplexing (FDD), the user equipment comprising:

• at least one transceiver;
• at least one processor;
• and
• at least one memory operably connectable to the at least one processor and storing instructions that, based on being executed by the at least one processor, perform operations comprising:
• receiving, from a base station, configuration information through higher-layer signaling;
• and
• receiving, from the base station, the SSB based on the configuration information,
• wherein an uplink transmission including at least one symbol within a minimum time for switching before the first symbol of the SSB and/or an uplink transmission including at least one symbol within a minimum time for switching after the last symbol of the SSB is not performed.
