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: 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 is configured to, when receiving a physical downlink control channel (PDCCH) indicating a change of a downlink (DL) bandwidth part (BWP), change the DL BWP based on the PDCCH indicating the change of the DL BWP, and not include a physical downlink shared channel (PDSCH) scheduled by a PDCCH received before receiving the PDCCH indicating the change of the DL BWP in a PDSCH candidate set, and transmit a semi-static HARQ-ACK codebook including hybrid automatic repeat request (HARQ)-ACK information of a physical downlink shared channel (PDSCH) corresponding to the PDSCH candidate set to a base station of the wireless communication system.

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.

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.
