Abstract: A method of transmitting a physical uplink control channel (PUCCH) in a wireless communication system and a device therefor are disclosed. Specifically, the method performed by a user equipment (UE) includes receiving, from a base station (BS), configuration information for performing transmission and reception on a per subslot basis, receiving, from the BS, multiple physical downlink shared channels (PDSCHs) based on the configuration information, and transmitting, to the BS, the PUCCH including hybrid automatic repeat request (HARQ)-acknowledgement (ACK) information for the multiple PDSCHs in a specific slot. The PUCCH includes a first PUCCH transmitted in a first subslot of the specific slot and a second PUCCH transmitted in a second subslot of the specific slot. The first PUCCH and the second PUCCH each are transmitted based on a separately constructed HARQ-ACK codebook.

Abstract: The present invention relates to a method for an NR (New Radio Access Technology) user equipment to transmit and receive a signal in a wireless communication system and an apparatus therefor. The method comprises the steps of checking a PDCCH (Physical Downlink Control Channel) order and, if the PDCCH order is checked, initiating a random access procedure. In this case, if a first uplink carrier and a second uplink carrier are configured, the random access procedure is configured to transmit a random access preamble via a specific uplink carrier corresponding to an indicator associated with the PDCCH order among the first uplink carrier and the second uplink carrier.
