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 UCl.

Abstract: A UE in a wireless communication system is disclosed. The UE includes a communication module and a processor for controlling the communication module. The processor determines a first cyclic shift (CS) value based on hybrid automatic repeat request acknowledgment (HARQ-ACK) information representing a response to a downlink channel having been received from a base station, determines a CS offset based on request information representing a request to be transmitted from the UE to the base station, determines a second CS value representing a degree of cyclic-shifting a base sequence to be used in a physical uplink control channel (PUCCH) based on the first CS value and the CS offset, and transmits the PUCCH for simultaneous transmission of the request information and the HARQ-ACK information using a sequence generated by cyclic-shifting the base sequence based on the second CS value.

Abstract: Disclosed is a method for a user equipment to transmit a physical uplink shared channel (PUSCH) to a base station in a wireless communication system. The user equipment may receive, from the base station, configuration information for PUSCH transmission and a physical downlink control channel (PDCCH) for scheduling repeated transmission of the PUSCH. Thereafter, the user equipment may determine one or more invalid symbols for the repeated transmission of the PUSCH, and may repeatedly transmit the PUSCH on symbols other than the determined symbols.

Abstract: A method for receiving downlink transmission by a terminal comprises the steps of: performing uplink transmission, which is related to channel occupancy shared between a base station and the terminal, to the base station; and receiving, from the base station, downlink transmission performed after a gap from a time point at which the base station has received the uplink transmission, wherein the downlink transmission is performed on the basis of channel access performed by the base station, the channel access is performed on the basis of the gap, and information included in the downlink transmission and a resource through which the downlink transmission is performed are determined on the basis of whether the base station has configured, for the terminal, a threshold value of energy detection for the channel occupancy.

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 configured to control the communication module. When a second physical uplink data channel transmission of the UE is scheduled to a time-frequency resource in which uplink control information (UCI) transmission of a first physical uplink data channel of the UE is scheduled, the processor is configured to transmit the UCI to a base station of the wireless communication system in a time-frequency resource except for a time-frequency resource in which a second physical uplink data channel transmission of the UE is scheduled.

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.
