Method for receiving physical control channel in wireless communication system, and device using same

A method of operating a user equipment for a wireless communication system, the method comprising:

• monitoring a physical downlink control channel (PDCCH) including a downlink control information (DCI);
• and
• determining a number of dynamic slot format information (SFI) bits based on a maximum value of slot format combination indexes capable of being indicated by dynamic SFI received by the user equipment, wherein each of the slot format combination indexes identifies a slot format combination configured for the user equipment, wherein the slot format combination indicates types of symbols included in one or more slots, and wherein each of the types of symbols is any one of a downlink symbol, an uplink symbol, and a flexible symbol,
• wherein the determining the number of the dynamic SFI bits comprises when the maximum value of the slot format combination indexes is 0, determining that the number of the dynamic SFI bits is 1.
