1. A method for transmitting buffer status report (BSR) by a node in a wireless communication system, the method comprising:
transmitting, to a parent node, a first BSR with starting a timer,
wherein the first BSR includes information related to data expected to be received from a child node;
based on the data being received from the child node, triggering a second BSR; and
wherein a transmission of the second BSR is postponed until the timer is expired,
wherein, based on receiving information related to additional data expected to be received from the child node during the timer is running, the timer is restarted,
wherein, based on an uplink grant which accommodates the data and the additional data being received from the parent node during the timer is running, the timer is stopped and the second BSR is canceled.
