Abstract: A method for performing an uplink transmission to a base station by a user equipment through an unlicensed cell in a wireless communication system is provided. The method includes: receiving an uplink grant that schedules the uplink transmission in at least one subframe from the base station; and performing the uplink transmission in the at least one subframe using at least one of a first type channel access or a second type channel access. The uplink transmission is performed using the second type channel access when all of the at least one subframe is included in a predetermined interval determined based on a downlink transmission through the unlicensed cell from the base station.

Abstract: The present invention relates to a method, device, and system for downlink data reception and HARQ-ACK transmission in a wireless communication system. According to the present invention, in the method, device, and system for downlink data reception and HARQ-ACK transmission, a first physical downlink control channel (PDCCH) for scheduling of a first physical downlink shared channel (PDSCH) is received, and a second PDCCH for scheduling of a second PDSCH is received. Thereafter, uplink control information (UCI) including a hybrid automatic repeat request (HARQ)-acknowledge (ACK) codebook for the first PDSCH and the second PDSCH is transmitted to a base station.

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 a base 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: The present invention relates to a wireless communication system. In particular, the present invention relates to a method including: receiving configuration information on a periodic signal through a higher layer signal, wherein a transmission/reception position of the periodic signal is configured to a first set of symbols within each slot which is set periodically; monitoring a PDCCH associated with a slot configuration of a first slot in order to receive slot configuration information for the first slot in which the transmission/reception position of the periodic signal is present; and performing a process for transmitting/receiving the periodic signal in the first slot, wherein when the first set of symbols within the first slot is designated as a flexible symbol by a higher layer, a transmission/reception of the periodic signal in the first slot is selectively performed according to a detection result of the PDCCH, and wherein the flexible symbol means a symbol whose purpose can be re-designated to DL, UL or flexible according to the slot configuration information of the PDCCH, and an apparatus therefor.
