    摘要： Provided is a method for transmitting, by a terminal, a physical uplink shared channel (PUSCH) to a base station in a wireless communication system. The method comprises: a step for receiving, from a base station, an radio resource control (RRC) signal including configuration information on a semi-static uplink symbol, a flexible symbol, and a downlink symbol; a step for receiving a physical downlink control channel (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.

    摘要： 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.

    摘要： 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.

    摘要： Disclosed are wireless communication system base stations. Each wireless communication base station comprises a communication module and a processor. When the base stations carry out DRS- and nonunicast data-multiplexed transmission, the processors select one channel access type among two channel access types according to whether both of two conditions are satisfied, the two conditions being that the duration of the DRS- and nonunicast data-multiplexed transmission is 1 ms or less, and the duty cycle of DRS transmission is 1/20 or less. Among the two channel access types, the first type is channel access in which random backoff is carried out using a variable-size contention window (CW), the size of the CW being determined according to channel access priority class; and the second type is channel access in which only single time interval-based LBT is carried out.
