1. A method performed by a Backhaul Adaptation Protocol (BAP) entity of an Integrated Access and Backhaul (IAB) node in a wireless communication system, the method comprising:
receiving a BAP Data protocol data unit (PDU) including a destination BAP address and a path identifier (ID), wherein the destination BAP address does not match a BAP address configured with the IAB node;
based on an ingress link of the BAP Data PDU belonging to a non-F1-terminating donor's topology and based on the destination BAP address and the path ID matching with at least one entry of a header rewriting configuration, rewriting a header of the BAP Data PDU by setting the destination BAP address and the path ID according to the at least one entry; and
submitting the BAP data PDU to an egress link.
