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: 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 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: Provided is a method for transmitting, by a terminal, a PUSCH to a base station in a wireless communication system. The method comprises: a step for receiving, from a base station, an RRC signal including configuration information on a semi-static uplink symbol, a flexible symbol, and a downlink symbol; a step for receiving a PDCCH for scheduling a PUSCH transmission including at least one PUSCH repetition; a step for determining whether at least one of the required number of symbols for transmitting the PUSCH repetition cannot transmit the PUSCH repetition; and a step for transmitting the PUSCH repetition to the base station on the basis of the determination on whether the PUSCH repetition cannot be transmitted. When the PUSCH repetition cannot be transmitted, at least one of the symbols is a symbol designated as a semi-static downlink symbol by the configuration information.

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.
