Method for determining slot format of user equipment in wireless communication system and user equipment using the same

A user equipment (UE), comprising:

• a transceiver;
• and
• at least one processor, and
• at least one computer memory operably connectable to the at least one processor and storing instructions that, when executed by the at least one processor, perform operations comprising:
• receiving, from a network, slot format information informing a first slot format for a plurality of normal symbols in a time duration, wherein each of the plurality of normal symbols includes a normal cyclic prefix (CP), and
• determining a second slot format for a plurality of extended symbols in the time duration based on the slot format information, wherein each of the plurality of extended symbols includes an extended CP,
• wherein a first subcarrier spacing (SCS) for the plurality of normal symbols is smaller than a second SCS for the plurality of extended symbols, where each of the plurality of normal symbol is longer than each of the plurality of extended symbols in a time domain,
• wherein based on an extended symbol of the plurality of extended symbols being overlapped with two normal symbols of the plurality of normal symbols in a time domain, the extended symbol is determined as a downlink symbol, an uplink symbol or a flexible symbol based on each of the two normal symbols being a downlink symbol, an uplink symbol or a flexible symbol,
• wherein based on the extended symbol being overlapped with a first normal symbol which is the downlink symbol and a second normal symbol which is the uplink symbol in a time domain, the extended symbol is determined as the flexible symbol, and
• wherein based on a specific extended symbol of the plurality of extended symbols being totally included in a normal symbol of the plurality of normal symbols in a time domain, a symbol type of the specific extended symbol is determined as a symbol type of the normal symbol.
