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 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: Base stations for wireless communication systems are disclosed. Each base station for wireless communication comprises a communication module and a processor. The processor performs random backoff-based channel access on multiple carriers, and performs transmission by using, among the multiple carriers, a carrier on which the channel access is successful. Each of the multiple carriers includes multiple listen before talk (LBT) subbands, wherein the LBT subband refers to a unit bandwidth for performing an LBT process.
