Abstract: The present disclosure provides a method for transmitting and receiving data based on a grid of a common resource block (RB) in a wireless communication system. More specifically, the method performed by a user equipment includes receiving a synchronization block from a base station; receiving, from the base station, first offset information representing an offset between a lowest subcarrier of a lowest resource block of the SSB and a first reference point based on a specific subcarrier spacing; receiving, from the base station, control information including information on the specific subcarrier spacing and information on a difference between a subcarrier spacing based reference point, to which the SSB is received, and the first reference point; and configuring a grid of a common resource block based on the first offset information and the control information.

Abstract: A method and apparatus for performing measurement based on synchronization signal (SS) blocks in a wireless communication system is provided. A user equipment (UE) which supports a new radio access technology (NR) receives a SS block measurement timing configuration (SMTC) from a network, and performs measurement based on the SS blocks in a duration which is determined based on the SMTC. The SS blocks are included in an active bandwidth part (BWP).

Abstract: Disclosed in the present application is a method by which a terminal, set by a first uplink carrier, receives downlink control information from a base station in a wireless communication system. Particularly, the method comprises the steps of: receiving setting information of a second uplink carrier through an upper layer; receiving, from the base station, the downlink control information for transmission of an uplink signal through the first uplink carrier or the second uplink carrier; and transmitting, to the base station, the uplink signal on the basis of the downlink control information, wherein the last bit of padding bits of the downlink control information is indicator information indicating either the first uplink carrier or the second uplink carrier.

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.

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.
