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 transmission and reception method of a radio signal by a terminal in a wireless communication system is disclosed. The method may comprise 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.

Abstract: Disclosed is a base station of a wireless communication system. Each base station for wireless communication comprises: a communication module; and a processor. The processor can receive signaling about a bandwidth part (BWP) from the base station, determine, on the basis of the signaling, an activated BWP among one or more BWPs set in an unlicensed band, and monitor a physical downlink control channel (PDCCH) in the activated BWP.

Abstract: Provided is a wireless communication user equipment that wirelessly communicates. The wireless communication user equipment includes a communication module; and a processor configured to control the communication module. The processor is configured to receive a demodulation reference signal (DM-RS) of data channel and receive the data channel based on the DM-RS of the data channel, wherein a time-frequency resource mapped to the DM-RS is predetermined. When the time-frequency resource mapped to the transmission of the DM-RS of the data channel overlaps with the time-frequency resource mapped to a different purpose from the transmission of the DM-RS, the processor is configured not to receive the DM-RS in a resource element (RE) overlapping with the time-frequency resource mapped to the different purpose in the time-frequency resource mapped to the transmission of the DM-RS. The DM-RS is a reference signal specific to the wireless communication device.

Abstract: The present specification relates to a device and method for transmitting an uplink control channel in a wireless communication system. Disclosed in the present specification is a method for transmitting a physical uplink control channel by means of a UE, the method including: a step for generating a first HARQ-ACK codebook related to a first PUCCH; a step for generating a second HARQ-ACK codebook related to a second PUCCH; and a step for transmitting simultaneously the first PUCCH and the second PUCCH or one PUCCH among the first PUCCH and the second PUCCH to a base station in one slot on the basis of a plurality of indicators. According to the present embodiments, the sequence for transmitting a plurality of PUCCHs including respectively different HARQ-ACKs in one slot is clarified, and thus the targeted performance of a 5G wireless communication system intended to simultaneously provide various types of traffic (eURLLC, eMBB) can be achieved.

Abstract: A base station in a wireless communication system is disclosed. Each base station in the wireless communication comprises: a communication module; and a processor. When the processor attempts to transmit a synchronization signal and PBCH block (SSB) at a SSB transmission candidate position in a discovery reference signal (DRS) transmission window, and fails to transmit an SSB at a first SSB transmission candidate location in a first DRS transmission window, the processor is configured to attempt to transmit the SSB at a second SSB transmission candidate position that is later than the first SSB transmission candidate position in the first DRS transmission window. The DRS transmission window is a time interval in which the base station can transmit the SSB. The SSB transmission candidate position indicates a time point at which the base station can start SSB transmission within the DRS transmission window.
