Abstract: The present specification relates to a method, an apparatus, and a system for transmitting uplink control information in a wireless communication system. The present specification provides a terminal comprising: a processor configured to determine a UCI to be dropped from among a first UCI having a first priority and a second UCI having a second priority or to multiplex the first UCI and the second UCI, under the condition in which a first PUCCH, to which the first UCI is mapped, and a second PUCCH, to which the second UCI is mapped, overlap in at least one symbol with respect to time; and a communication module configured to transmit an undropped UCI from among the first UCI and the second UCI to a base station or transmit a third PUCCH, in which the first UCI and the second UCI are multiplexed to be mapped thereto, to the base station according to the control of the processor. Communication reliability can be increased by multiplexing and transmitting UCIs having different priorities or later retransmitting a dropped UCI.

Abstract: Disclosed is a method by which a terminal transmits a physical uplink shared channel (PUSCH) to a base station in a wireless communication system. The terminal can receive, from the base station, configuration information for allocating a resource for transmitting a transport block (TB) through the PUSCH, and map the TB to a plurality of slots constituting the resource on the basis of the configuration information. Thereafter, the terminal can transmit the TB on the plurality of slots through the PUSCH.

Abstract: The present invention relates to a method and an apparatus for configuring downlink and uplink radio resources in an unlicensed band. The present invention provides a method comprising the steps of: receiving information indicating at least one synchronization signal/physical broadcast channel (SS/PBCH) block index from a base station in the unlicensed band; and receiving downlink control information (DCI) for allocation of resources for a physical downlink shared channel (PDSCH) in the unlicensed band from the base station. Therefore, efficient transmission of downlink and/or uplink data or control information in an unlicensed band is possible.

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.
