Abstract: Disclosed is a method by which a terminal transmits an acknowledgement (ACK)/negative ACK (NACK) signal in a wireless communication system. In particular, the method is characterized by receiving data from a base station, generating an ACK signal or a NACK signal corresponding to the data, transmitting the ACK signal to the base station on the basis of a first hopping pattern when the ACK signal is generated according to the data, and transmitting the NACK signal to the base station on the basis of a second hopping pattern different from the first hopping pattern when the NACK signal is generated according to the data. The terminal is capable of communicating with at least one of another terminal, a terminal related to an autonomous driving vehicle, the base station or a network.

Abstract: A method of receiving, by a user equipment, a physical downlink shared channel (PDSCH) in a wireless communication system. The method includes receiving, from a base station (BS), a higher layer signal including first information for an uplink (UL)-downlink (DL) configuration; repeatedly receiving, from the BS, a first transport block (TB) via the PDSCH based on the first information for the UL-DL configuration; receiving, from the BS, a first control channel including second information for the UL-DL configuration; and discarding a second control channel based on: (i) the second control channel scheduling a PDSCH repetition of a second TB in a transmission time unit, (ii) the first information for the UL-DL configuration indicating the transmission time unit as an uplink, and (iii) the second information for the UL-DL configuration indicating the transmission time unit as a downlink.

Abstract: Disclosed are a method for transmitting an uplink channel in a wireless communication system, and an apparatus therefor. Specifically, a method by which a terminal transmits uplink control information comprises the steps of: identifying a resource region allocated to a first uplink control channel for transmitting first uplink control information, and a resource region allocated to a second uplink control channel for transmitting second uplink control information; and transmitting a specific modulation symbol to a base station using a specific uplink resource, if the transmission of the first uplink control channel and the transmission of the second uplink control channel overlap.

Abstract: Disclosed is a method for determining transmit power in a wireless communication system according to one embodiment of the present invention. The method, which is performed by a terminal, comprises the steps of: receiving a semi-persistent scheduling (SPS) setting of a short transmission time interval (sTTI); receiving control information for SPS-related transmit power control according to the received setting; and determining an SPS-related transmit power by using a transmit power control (TPC) command included in the received control information, wherein the control information may include a TPC command for each of a plurality of TTI lengths, which includes an SPS-related TPC command of the sTTI.
