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: A user equipment generates an HARQ-ACK codebook comprising HARQ-ACK bits for semi-persistent scheduling (SPS) physical downlink shared channels (PDSCHs) based on multiple SPS configurations, and transmits the HARQ-ACK codebook. In the HARQ-ACK codebook, with respect to an SPS configuration index and a serving cell index, an HARQ-ACK bit for an SPS PDSCH in a slot of a lower slot index precedes an HARQ-ACK bit for an SPS PDSCH in a slot of a higher slot index, and with respect to each serving cell index, an HARQ-ACK bit for an SPS PDSCH based on an SPS configuration having a lower SPS configuration index precedes an HARQ-ACK bit for an SPS PDSCH based on an SPS configuration having a higher SPS configuration index.

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.
