Abstract: The present invention provides a method for a base station to transmit a downlink signal, in order to reduce interference between uplink transmission and downlink transmission in a wireless communication system. Particularly, the method is characterized by: a step of setting a power decrease region in which downlink transmission power is transmitted by being lower than that of another region; a step of separating and generating a first transmission block corresponding to the power decrease region, and a second transmission block not corresponding to the power decrease region; and a step of mapping downlink data to the first transmission block and the second transmission block, respectively, wherein the first transmission block is transmitted with the power allocated to the power decrease region, and the second transmission block is transmitted with the power allocated to the region other than the power decrease region.

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 default subcarrier spacing for use in transmission/reception of a broadcast channel is defined for each frequency range. A base station transmits a broadcast channel in a frequency band, using the default subcarrier spacing defined for a frequency range to which the corresponding frequency band belongs. A user equipment attempts to detect a broadcast channel in the frequency band where a cell search is being attempted, using the default subcarrier spacing defined for a frequency range to which the frequency band belongs.

Abstract: A method of a user equipment (UE) in a wireless communication system includes receiving resource allocation information related to a configured grant (CG)-based uplink transmission, and transmitting a CG physical uplink shared channel (CG PUSCH) based on the resource allocation information. CG uplink control information (CG UCI) is multiplexed on the CG PUSCH. The CG UCI and control information different from the CG UCI are jointly encoded and multiplexed in the CG PUSCH, based on the control information being multiplexed in the CG PUSCH. One of a beta offset for the CG UCI or a beta offset for the control information is applied to the joint encoding.
