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. 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: A terminal of a wireless communication system comprises a communication module and a processor for controlling the communication module. The processor generates a hybrid automatic repeat request (HARQ)-ACK codebook including one or more bits indicating whether reception of a channel or signal is successful, and transmits the HARQ-ACK codebook to a base station of the wireless communication system. The HARQ-ACK codebook is generated on the basis of a slot corresponding to a value of an HARQ-ACK feedback timing parameter (K1) set in a sub-slot level, and each of bits configuring the HARQ-ACK codebook corresponds to at least one sub-slot form among a plurality of sub-slots included in the slot.
