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 generates a preemption indicator indicating a preempted resource. In this case, the resource indicated by the preemption indicator does not include an orthogonal frequency divisional multiplexing (OFDM) symbol configured as an uplink (UL) symbol by a radio resource control (RRC) signal. The processor is configured to transmit the preemption indicator to a user equipment of the wireless system based on a predetermined period.

Abstract: The present invention relates to a method, device, and system for downlink data reception and HARQ-ACK transmission in a wireless communication system. According to the present invention, in the method, device, and system for downlink data reception and HARQ-ACK transmission, a first physical downlink control channel (PDCCH) for scheduling of a first physical downlink shared channel (PDSCH) is received, and a second PDCCH for scheduling of a second PDSCH is received. Thereafter, uplink control information (UCI) including a hybrid automatic repeat request (HARQ)-acknowledge (ACK) codebook for the first PDSCH and the second PDSCH is transmitted to a base station.

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. 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.
