Method and apparatus for transmitting and receiving control information and data information in wireless communication system

An operation method of a terminal in a wireless communication system, the operation method comprising:

• receiving a subcarrier spacing configuration indicating a subcarrier spacing of 60 kHz and cyclic prefix information indicating an extended cyclic prefix from a base station through higher layer signaling;
• receiving a slot format indicator with a first value;
• determining a symbol having the extended cyclic prefix as a flexible symbol in case that at least one of symbols having a normal cyclic prefix and overlapping the symbol is a flexible symbol according to a slot format indicated by the first value;
• determining the symbol having the extended cyclic prefix as an uplink symbol in case that all symbols having the normal cyclic prefix and overlapping the symbol are uplink symbols according to the slot format indicated by the first value;
• and
• determining the symbol having the extended cyclic prefix as downlink symbol in case that all symbols having the normal cyclic prefix and overlapping the symbol are downlink symbols according to the slot format indicated by the first value.
