Provided are a method for operating an IAB node connected to a plurality of parent nodes in a wireless communication system, and an apparatus using the method. The method comprises: monitoring all pieces of AI-DCI respectively received from the plurality of parent nodes; and determining whether or not a soft resource is available to a DU of the IAB node, in consideration of all results of the monitoring.

Method for operating IAB node connected to plurality of parent nodes in wireless communication system, and apparatus using method

Provided are an operating method for an IAB node including a DU and an MT in a wireless communication system, and a device. The method receives first resource direction information about the DU and second resource direction information about the MT, wherein each of the first and second resource direction information indicates the direction of each resource as being downlink, uplink or flexible. The IAB node determines, for a certain resource from among the resources, whether the DU and the MT can operate at the same time on the basis of the direction indicated by the first resource direction information and the direction indicated by the second resource direction information.

Operating method for IAB node in wireless communication system, and device using method

The present disclosure proposes a synchronization method for the DU transmission timing of the IAB node.

Coverage enhancement

The present disclosure proposes various methods for improving coverage. According to an embodiment of the present disclosure, when an unavailable resource exists in a resource set configured for repeated transmission of a physical uplink channel, the UE may determine a resource capable of actually performing repeated transmission of a physical uplink channel within the resource set. According to another embodiment of the present disclosure, when the terminal receives the TPC command within the resource corresponding to the DMRS bundle, the terminal may perform power control based on the TPC command after the resource.
