Abstract: Provided are a node operation method in a wireless communication system and an apparatus using the method. The method includes receiving first allocation information related to communication with a parent node and second allocation information related to communication with a child node and performing communication with the parent node or child node based on the first and the second allocation information. The first allocation information informs of resource type of a specific resource as one of three, and the second allocation information informs of resource type of the specific resource as one of seven. When the second allocation information informs the specific resource as a hard resource which can be always used for communication with the child node, the specific resource is used for communication with the child node irrespective of the first allocation information.

Abstract: A method and a device allowing a terminal to receive a signal in a wireless communication system, according to one embodiment of the present invention, configure a search space set constructed in a hierarchical structure, and can monitor control channel candidates in the configured search space set. Particularly, when the hierarchical structure is constructed, a control channel candidate of a lower aggregation level (AL) in the search space set is randomly arranged on the basis of a control channel candidate of a top AL in the search space set, wherein a portion or the entire area of the control channel candidate of the lower AL can be arranged so as to overlap the control channel candidate of the top AL.

Abstract: A method of determining a slot format in a wireless communication system, where the method is performed by a user equipment (UE) and includes: receiving, from a network, slot format information informing a first slot format for a plurality of normal symbols that are arranged within a period of time, wherein each of the plurality of normal symbols includes a normal cyclic prefix (CP). The method further includes: based on the received slot format information informing the first slot format, determining a second slot format for a plurality of extended symbols that are arranged within the period of time, wherein each of the plurality of extended symbols includes an extended CP.
