Abstract: The present invention relates to a transmission and reception method of a radio signal by a terminal in a wireless communication system. According to the present specification, disclosed is a method comprising the steps of: determining whether or not transmission of an uplink radio signal or reception of a downlink radio signal allocated to a terminal is possible on a slot configured to comprise at least one of one or more downlink symbols for downlink transmission, one or more flexible symbols and one or more uplink symbols for uplink transmission; and controlling the transmission of the uplink radio signal or the reception of the downlink radio signal on the basis of the determination. According to the present invention, the terminal can transmit the uplink radio signal even if the configuration of the slot is changed, and thus uplink radio signal transmission omission or unnecessary retransmission of the uplink radio signal can be prevented. And by means of defining valid timing of the uplink signal such as a physical random access channel, the frequency efficiency of the network can be increased and the energy consumption of the terminal can be reduced.

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. The processor receives a radio resource control (RRC) signal from a base station of the wireless communication system through the communication module and determines a time-frequency resource corresponding to at least one resource-set indicated by the RRC signal. The processor receives a physical control channel from the base station through the communication module, determines a time-frequency resource domain in which physical data channel reception of the terminal is scheduled by the physical control channel, and receives a physical data channel based on a time-frequency resource in which the physical data channel reception of the terminal is scheduled and a time-frequency resource in which the at least one resource-set overlap. The resource-set is a set of time-frequency resources.

Abstract: Disclosed is a base station in a wireless communication system. Each base station in wireless communication comprises: a communication module; and a processor. The processor generates a hybrid automatic repeat request (HARQ)-ACK codebook comprising one or more bits and indicating whether or not reception of a channel or signal is successful, and transmits the HARQ-ACK codebook to the base station.

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 is disclosed. A wireless communication base station comprises a communication module and a processor. The processor receives DCI of a physical downlink control channel (PDCCH) for scheduling a physical uplink shared channel (PUSCH) transmission over a plurality of slots and multiplexes hybrid automatic repeat request (HARQ)-ACK information to the PUSCH transmission by applying a value in a downlink assignment index (DAI) field of the DCI to each slot where the HARQ-ACK information is multiplexed to the PUSCH transmission over the plurality of slots.

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.

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.
