Abstract: Provided are a method of adjusting uplink timing in a wireless communication system and an apparatus therefor. Specifically, a method for a user equipment to adjust uplink timing in a wireless communication system includes transmitting, to a base station, an uplink signal, receiving, from the base station, a timing advance (TA) command configured based on the uplink signal, and performing uplink transmission to the base station by applying a timing advance (TA) indicated by the TA command. The TA command may be interpreted based on subcarrier spacing of at least one frequency resource region to which the TA is to be applied.

Abstract: Provided are a method and device for transmitting and receiving a signal in a wireless communication system according to an embodiment of the present invention, the method comprising: receiving DCI for scheduling a PUSCH; and transmitting the PUSCH on the basis of the DCI. An FDRA field in the DCI includes LSBs of K bits including information about an RB set. The K bits are converted into L bits on the basis of the number N of RB sets set in the current active BWP being different from the number M of RB sets set in a specific BWP.
