    Abstract: The present invention relates to a wireless communication system and, in particular, to a method and an apparatus therefor, the method comprising: receiving first downlink control information (DCI) including downlink scheduling information and information on a HARQ-ACK feedback type; transmitting a HARQ-ACK feedback regarding a first physical downlink shared channel (PDSCH) corresponding to the downlink scheduling information, on the basis of the HARQ-ACK feedback type indicating a first type; and delaying transmission of the HARQ-ACK feedback regarding the first PDSCH or transmitting a previously-received HARQ-ACK feedback regarding a second PDSCH, on the basis of the HARQ-ACK feedback type indicating a second type.

    Abstract: A method of a user equipment (UE) in a wireless communication system supporting an unlicensed band, includes performing a channel access procedure (CAP) based on a first channel access priority class parameter; receiving, from a base station (BS) a signal including a second channel access priority class parameter and scheduling information for uplink transmission in a specific time resource; performing the CAP based on the first channel access priority class parameter continuously based on that the first channel access priority class parameter is equal to or greater than the second channel access priority class parameter indicated in the signal; performing the CAP based on the second channel access priority class parameter indicated in the signal based on that the first channel access priority class parameter is less than the second channel access priority class parameter; and performing uplink transmission based on a result of the performed CAP.

    Abstract: The present disclosure relates to a wireless communication system and, specifically, to a method and an apparatus therefor, the method comprising the steps of: receiving information relating to a BWP for reception of a downlink signal; receiving type information of a base station; receiving frequency resource allocation information for configuring a control resource set (CORESET) in the BWP; and receiving a physical downlink control channel (PDCCH) in the BWP on the basis of the type information and the frequency resource allocation information, wherein the BWP includes N number of frequency units in which a CAP for an unlicensed band is performed, N is an integer of two or larger, particular frequency resource sections are configured between the frequency units, the number of the particular frequency resource sections is N-1, and whether the PDCCH is received in the particular frequency resource sections is determined on the basis of the type information.
