1. A method performed by a child node of an integrated access and backhaul (IAB) for providing a buffer status report (BSR) in a network, the method comprising:
receiving, from a parent node of the IAB, information on an identity (ID) of a logical channel group (LCG) via a radio resource control (RRC) signaling, in case that a number of LCGs to which logical channels are allocated is greater than a first maximum number of LCGs, wherein the information on the ID of the LCG is associated with a second maximum number of LCGs being 256; and
selecting a format of the BSR from among at least two BSR formats,
wherein the format of the BSR is selected based on a number of LCGs having data available for transmission and the information on the ID of the LCG.
