1. A method performed by a central unit (CU) of a donor node in a communication system, the method comprising:
generating a configuration message including:
address information of a receiving node over a backhaul link channel,
channel identification information for the backhaul link channel, wherein the backhaul link channel comprises a radio link control (RLC) channel used for a link between a first integrated access and backhaul (IAB) node of a distributed unit (DU) and the receiving node, and
indication information for indicating a type of information carried over the backhaul link channel, wherein the type of information is one of types including a user equipment (UE) associated F1 application protocol (F1AP) signaling or a non-UE associated F1AP signaling; and
transmitting, to the first IAB node, the configuration message; and
transmitting, to the first IAB node, a radio resource control (RRC) reconfiguration message including identification information of a logical channel corresponding to the backhaul link channel and information about priority of the logical channel corresponding to the backhaul link channel.
