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.

Abstract: Based on a first cell slot N scheduled for a HARQ-ACK transmission for PDSCH reception and a pre-determined rule for a PUCCH cell change, a UE may determine a PUCCH cell from among a plurality of cells including the first cell and a second cell different from the first cell; determine a PUCCH cell slot associated with the first cell slot N, from among slots on the PUCCH cell associated with the first cell slot N; and determine a target slot for which the HARQ-ACK transmission is to be delayed, on the basis of the HARQ-ACK transmission overlapping with a downlink symbol on the PUCCH cell slot on the PUCCH cell associated with the first cell slot N.

Abstract: The present disclosure relates to a wireless communication system, and specifically to a method and a device therefor, the method comprising: a step for receiving configuration information about a plurality of cells comprising (i) a first cell having a first HARQ process index and operable with a first priority, and (ii) a second cell having only a second HARQ process index and operating only with a second priority lower than the first priority; a step for receiving an HARQ-ACK feedback request via DCI; and a step for transmitting an HARQ-ACK codebook for the plurality of cells on the basis of the HARQ-ACK feedback request, wherein HARQ-ACK information in the HARQ-ACK codebook is in descending order of first cell index and then HARQ process index, and the HARQ-ACK information about the second cell is excluded from the HARQ-ACK codebook on the basis that the first priority is indicated by the DCI.

Abstract: A UE may comprise: determining that uplink channels with different priorities overlap with respect to time; determining whether the uplink channels with the different priorities satisfy multiplexing timeline conditions; determining, on the basis of the non-satisfaction of the multiplexing timeline conditions by the uplink channels with different priorities, an uplink channel to be multiplexed, for uplink channels with the highest priority, that satisfy the multiplexing timeline conditions, from among the different priorities; and transmitting the uplink channel to be multiplexed.

Abstract: According to an embodiment of the present disclosure, a user equipment (UE) may obtain fixed frame period (FFP)-related information, and perform clear channel assessment (CCA) for at least one FFP starting with a UE-initiated channel occupancy time (COT) for transmission of an uplink signal. The FFP-related information may include information about an FFP starting offset and information about an FFP duration or period, and the UE may identify a starting time of the FFP, based on the FFP starting offset having an orthogonal frequency division multiplexing (OFDM) symbol-level granularity.
