Claim 0:
1. A first integrated access and backhaul (IAB) node in a communication system, the first IAB node comprising:
a transceiver; and
a controller configured to:
receive, from a third node, identification information indicating a second node which is to receive information on an available buffer size of the first IAB node from the first IAB node,
receive, from the second node indicated by the identification information received from the third node, information indicating to report the information on the available buffer size of the first IAB node, via an adaptation layer associated with an IAB network, and
transmit, to the second node indicated by the identification information received from the third node, the information on the available buffer size of the first IAB node, via the adaptation layer associated with the IAB network,

wherein the first IAB node comprises a function of distributed unit for a base station and a function for a user equipment (UE),
wherein the second node corresponds to an IAB node or a distributed unit of the base station, and
wherein the third node corresponds to a donor central unit of the base station.
