Abstract: Disclosed is a method for a user equipment to transmit a physical uplink shared channel (PUSCH) to a base station in a wireless communication system. The user equipment may receive, from the base station, configuration information for PUSCH transmission and a physical downlink control channel (PDCCH) for scheduling repeated transmission of the PUSCH. Thereafter, the user equipment may determine one or more invalid symbols for the repeated transmission of the PUSCH, and may repeatedly transmit the PUSCH on symbols other than the determined symbols.

Abstract: One aspect of the present invention discloses a terminal of a wireless communication system. The terminal comprises a communication module and a processor for controlling the communication module, wherein the processor generates a hybrid automatic repeat request (HARQ)-ACK codebook including one or more bits indicating whether reception of a channel or signal is successful, and transmits the HARQ-ACK codebook to a base station of the wireless communication system, wherein the HARQ-ACK codebook is generated on the basis of a slot corresponding to a value of an HARQ-ACK feedback timing parameter (K1) set in a sub-slot level, and each of bits configuring the HARQ-ACK codebook corresponds to at least one sub-slot form among a plurality of sub-slots included in the slot.

Abstract: A base station of a wireless communication system is disclosed. The base station of wireless communication includes a communication module and a processor. The processor is configured to receive a grant for scheduling a plurality of uplink transmissions from the base station, and when the UE attempts to a first fixed duration-based channel access for a first transmission which is one of the plurality of uplink transmission and fails in the first fixed duration-based channel access, attempt to a second fixed duration-based channel access for a second transmission which is a transmission following the first transmission.

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: Disclosed is a method by which a terminal transmits a physical uplink shared channel (PUSCH) to a base station in a wireless communication system. The terminal can receive, from the base station, configuration information for allocating a resource for transmitting a transport block (TB) through the PUSCH, and map the TB to a plurality of slots constituting the resource on the basis of the configuration information. Thereafter, the terminal can transmit the TB on the plurality of slots through the PUSCH.
