Abstract: Provided are a method of operating a node in a wireless communication system and a device using the same. The method includes: connecting to a parent node through an initial access process; receiving, from the parent node, first allocation information related with communication with the parent node and second allocation information related with communication with a child node; and communicating with the parent node or the child node using a specific resource based on the first allocation information and the second allocation information. When the second allocation information indicates the specific resource as a hard resource that is always available for communication with the child node, the specific resource is used for communication with the child node regardless of the first allocation information.

Abstract: The present disclosure provides a method for mapping a reference signal (RS) sequence to a physical resource in a wireless communication system. Specifically, the method performed by a terminal comprises the steps of: receiving, from a network, length information indicating a length of the RS sequence and offset information indicating a start position of the RS sequence mapped to the physical resource allocated to the terminal; generating the RS sequence on the basis of the received length information; and mapping the generated RS sequence to the physical resource on the basis of the offset information.

Abstract: The present specification provides a method for transmitting and receiving data by a relay node in a wireless communication system and an apparatus therefor. The relay node receives configuration information from a network node, wherein the configuration information may include a timing offset for transmitting downlink data. The relay node transmits the downlink data to a second relay node on the basis of the configuration information, in which transmission timing of the downlink data may be determined on the basis of the timing offset and a timing advance (TA).

Abstract: An initial access method of an integrated access and backhaul (IAB) node in a wireless communication system and an apparatus using the method are provided. The method includes: receiving, from a parent node, a synchronization signal block (SSB) and system information; and performing a random access procedure with the parent node on the basis of the SSB and the system information, wherein the SSB and the system information are received through a resource allocated to an access link of the parent node, and the random access step is performed through a resource allocated to the backhaul link of the parent node, and the random access step is performed using resources determined differently depending on whether the TAB node is a relay node or a terminal.

Abstract: 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 communicating with the parent node or the child node using a particular resource based on the first allocation information and the second allocation information. The first allocation information indicates a resource type of the particular resource as one of three resource types, the second allocation information indicates the resource type of the particular resource as one of seven resource types. When the second allocation information indicates the particular resource as a soft downlink, soft uplink, or soft flexible resource and when it is not explicitly indicated that the particular resource is available for the communication with the child node, the particular resource is used for the communication with the parent node.

Abstract: The present specification provides a method for configuring a common search space (CSS) in a wireless communication system. Specifically, a method performed by a network may comprise the steps of: acquiring, from at least one terminal, information on a bandwidth of the at least one terminal; determining a particular subband indicating a bandwidth unit available for communication with the terminal; determining the number of particular subbands on the basis of the determined particular subband and the acquired information on the bandwidth of the terminal; and mapping, on the basis of the determined number of particular subbands and the aggregation level of the CSS, a part of the aggregation level to each particular subband. Therefore, it is possible to efficiently use radio resources through the CSS configuration method proposed in the present specification.

Abstract: Disclosed herein is a method for determining a resource area to be allocated to a bandwidth part (BWP) in a wireless communication system. More specifically, the method performed by a terminal includes: receiving, from a network, a first resource allocation field associated with a resource allocation group (RBG) size for a first BWP and a second resource allocation field associated with an RBG size for a second BWP, on the first BWP; and when the size of the first resource allocation field is greater than the size of the second resource allocation field, determining a resource area to be allocated to the second BWP, based on a value of the first resource allocation field, which corresponds to the size of the second BWP, starting from a predefined point.
