Abstract: The present disclosure is related to a method, by a user equipment (UE), for transmitting uplink data through a preconfigured uplink resource (PUR) in a wireless communication system and apparatus therefor. According to the present disclosure, the method comprises, the UE receives, from a base station, PUR configuration information for uplink data transmission based on the PUR in a radio resource control (RRC) connected state; transitions from the RRC connected state to an RRC idle state; performing a timing advance (TA) update procedure based on whether a TA related to uplink transmission timing is valid; and transmits, to the base station, the uplink data on a first resource of the PUR, wherein, based on that a specific resource included in the PUR is included in a TA update performing interval, a transmission for the uplink data on the specific resource is dropped, and a value of a counter for release of the PUR is held regardless of dropping of the uplink data on the specific resource.

Abstract: Disclosed is a method of receiving a physical downlink control channel (PDCCH) through a search space (SS) set by a user equipment (UE) in a wireless communication system. The method includes transmitting first information related to the number of X slots and second information related to the number of at least one Y slot, and receiving a PDCCH through a UE-specific SS (USS) set within the at least one Y slot, based on the first information and the second information. The at least one Y slot is included in the X slots, and X and Y are positive integers.

Abstract: The present invention relates to a wireless communication system, and more particularly, to a method of transmitting and receiving a radio signal and an apparatus therefor. The method comprises the steps of receiving data in a time unit #n of a first frequency band and transmitting A/N in a time unit #m+k of a second frequency band in response to the data. In this case, the first frequency band and the second frequency band have different subcarrier spacing and a time unit #m of the second frequency band indicates the last time unit among a plurality of time units of the second frequency band corresponding to the time unit #n of the first frequency band.

Abstract: The present disclosure provides a method and apparatus for transmitting and receiving a signal in a wireless communication system. When a user equipment (UE) is configured with M resources within one periodicity based on a semi-persistent scheduling (SPS) configuration, a base station may configure N resources actually available to the UE in downlink control information (DCI). The UE may select some of the N resources to receive data. Accordingly, resources may be flexibly allocated to a plurality of UEs without delay due to data jitter.
