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. The processor is configured to, when receiving a physical downlink control channel (PDCCH) indicating a change of a downlink (DL) bandwidth part (BWP), change the DL BWP based on the PDCCH indicating the change of the DL BWP, and not include a physical downlink shared channel (PDSCH) scheduled by a PDCCH received before receiving the PDCCH indicating the change of the DL BWP in a PDSCH candidate set, and transmit a semi-static HARQ-ACK codebook including hybrid automatic repeat request (HARQ)-ACK information of a physical downlink shared channel (PDSCH) corresponding to the PDSCH candidate set to a base station of the wireless communication system.

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. 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.
