    Abstract: The purpose of the present invention is to provide a method for controlling power of an IAB node, and a device using the method. A power control method performed by an IAB node for the purpose comprises: receiving power information, wherein the power information informs the IAB node of a configured power control method; and on the basis that the sum of an MT power for MT transmission and a DU power for DU transmission is greater than the maximum transmission power allocated to the LAB node, performing power control on at least one of the MT power and the DU power on the basis of the power information, wherein an MT resource on which the MT transmission is performed and a DU resource on which the DU transmission is performed overlap in a time domain.

    Abstract: The present specification provides a method for configuring transmission or reception timing of a wireless device, and a device using the same method. A method for performing uplink transmission by a wireless device in a wireless communication system may comprise a method in which, on the basis that a first serving cell and a second serving cell are included in a particular timing advance group (TAG), and first uplink transmission timing and second uplink transmission timing are different from each other, the uplink transmission is performed on the basis of uplink transmission timing coinciding with reference uplink transmission timing applied to a downlink timing reference cell among the first uplink transmission timing and the second uplink transmission timing.

    Abstract: Provided are a method and device for operating an IAB node including an MT and a DU in a wireless communication system. The method involves receiving first slot format information, time domain HSNA information, and frequency domain HSNA information about the DU, receiving second slot format information about the MT, and determining operation resources of the MT and the DU on the basis of at least one of the first slot format information, the time domain HSNA information, the frequency domain HSNA information, and the second slot format information. Whether to apply the frequency domain HSNA information may be determined according to whether a slot supports the simultaneous operation of the MT and the DU. In addition, provided are a method and device for notifying availability information about soft resources in a time domain and availability information about soft resources in a frequency domain by using an existing DCI format.

    Abstract: The present disclosure relates to a wireless communication system. Particularly, a communication method and an apparatus for the same are provided, in which configuration information related to random access of a user equipment (UE) is received from an upper node, first time resource information related to random access of the relay node is received from the upper node, and random access is performed to the upper node based on the configuration information and the first time resource information. The configuration information includes second time resource information including a periodicity of the random access of the UE and a plurality of random access occasions within the periodicity, and the first time resource information and the second time resource information do not overlap with each other in time resources.
