Abstract: According to the present invention, a first physical downlink control channel (PDCCH) and a second PDCCH can be transmitted to user equipment. A first physical downlink data channel (PDSCH) corresponding to the first PDCCH, and a second PDSCH corresponding to the second PDCCH can be transmitted to the user equipment. When the first PDSCH has a lower decoding priority than the second PDSCH, and the decoding timing of the first PDSCH and the decoding timing of the second PDSCH overlap, the user device may decode the second PDSCH and not the first PDSCH at the decoding timing, and transmit information with respect to the first PDSCH as first ACK/NACK information. As a reply to the first ACK/NACK information, a third PDCCH not having a corresponding PDSCH may be transmitted to the user equipment.

Abstract: A disclosure of the present specification provides a method for performing random access by a terminal. The method may comprise the steps of: selecting, by the terminal, a first resource among a plurality of resources for a physical random access channel (PRACH), wherein the plurality of resources exist for each numerology, and the numerology is defined by a cycle prefix (CP) length and a subcarrier spacing; and transmitting, by the terminal, the PRACH on the first resource through a first numerology when the selected first resource is for the first numerology.

Abstract: A method for transmitting a physical uplink shared channel (PUSCH) is discussed. The method is performed by a wireless device and includes receiving downlink control information (DCI), which is repeated on a plurality of downlink subframes, identifying a last subframe on which the repetition is completed, determining that the identified last subframe is not used for determining a start subframe to repeatedly transmit the PUSCH, substituting the last subframe with a first subframe usable for determining the start subframe to transmit the PUSCH after the identified last subframe, based on the determination that the identified last subframe is not used for determining the start subframe; determining the start subframe to transmit the PUSCH, based on the first subframe other than the last subframe, and transmitting the PUSCH repeated over a plurality of subframes starting from the determined start subframe.

Abstract: Disclosed is a method for a terminal to transmit an uplink data signal in a narrowband wireless communication system. Specifically, the method comprises the steps of: receiving, from a base station, a downlink control signal including resource allocation information for resource blocks continuously allocated for the uplink data signal within allocable resource blocks; and transmitting the uplink data signal to the base station using the downlink control signal, wherein the continuously allocated resource blocks are updated to include a center resource block, when the allocable resource blocks include the center resource block of a system bandwidth.

Abstract: Provided is a communication method for interference avoidance in an unlicensed band. A transmission node transmits in the unlicensed band a preemption signal to a target reception node. Upon receiving a ready signal from the target reception node, the transmission node transmits in the unlicensed band a data signal to the target reception node. The preemption signal is transmitted by means of a narrow beam having substantially the same width and direction as the data signal.

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.
