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. The processor receives a radio resource control (RRC) signal from abase 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.

Abstract: A base station and a user equipment of a wireless communication system are disclosed. Each of the base station and the user equipment of the wireless communication includes a communication module; and a processor. The processor is configured to receive signaling information related to the start of uplink (UL) transmission from the base station through the communication module. The processor is configured to determine whether to perform a UL transmission using a partial subframe based on the signaling information. When the processor performs the UL transmission using the partial subframe, the processor is configured to determine a symbol configuration of the partial subframe based on the signaling information and perform, through the communication module, the UL transmission using the partial subframe according to the symbol configuration. At this time, the partial subframe is a subframe which occupies less than 14 symbols.

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.
