Abstract: A base station in a wireless communication system is provided. Each base station for wireless communication comprises: a communication module; and a processor. The processor is configured to determine the number of dynamic slot format information (SFI) bits based on a maximum value of a slot format combination index which can be indicated by dynamic SFI transmitted to a terminal, and monitor a physical downlink control channel (PDCCH) including the dynamic SFI based on the number of the dynamic SFI bits. The slot format combination index identifies a slot format combination configured for the terminal. The slot format combination indicates a type of a symbol included in one or more slots, and the type of the symbol is one among a downlink symbol, an uplink symbol, and a flexible symbol.

Abstract: A base station of a wireless communication system is disclosed. The base station of the wireless communication includes: a communication module; and a processor configured to control the communication module. When a second physical uplink data channel transmission of the UE is scheduled to a time-frequency resource in which uplink control information (UCI) transmission of a first physical uplink data channel of the UE is scheduled, the processor is configured to transmit the UCI to a base station of the wireless communication system in a time-frequency resource except for a time-frequency resource in which a second physical uplink data channel transmission of the UE is scheduled.
