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: An operating method of a node in a wireless communication system, and a device using the method are provided. The method transmits a link instability signal notifying a child node of the instability of a link if the link with a parent node is unstable, monitors, during a connection recovery time, whether a link recovery signal is received from the parent node, and transmits, to the child node, a handover trigger signal if the link recovery signal has not been received within the connection recovery time.
