Classification: CPC H | IPC H

Claim 0:
1. A communication apparatus, comprising:
at least one processor; and
one or more memories coupled to the at least one processor and storing programming instructions for execution by the at least one processor to perform operations comprising:
receiving first information from an integrated access and backhaul (IAB) node, wherein the first information is used to request to allocate internet protocol (IP) address to the IAB node, wherein the communication apparatus is a centralized unit (CU) of an IAB donor or an apparatus included in the CU of the IAB donor, and wherein the first information comprises a quantity of IP addresses requested to be allocated to the IAB node or a quantity of IP addresses requested to be allocated to an F1 control plane (F1-C) interface or an F1 user plane (F1-U) interface, wherein the F1-C interface is a communication interface between the IAB node and a CU-control plane (CU-CP) of the IAB donor, and the F1-U interface is a communication interface between the IAB node and a CU-user plane (CU-UP) of the IAB donor;
in response to receiving the first information, sending, to a distributed unit (DU) of the IAB donor, a request for allocating IP address to the IAB node;
receiving, from the DU of the IAB donor, one or more IP addresses that are allocated to the IAB node; and
sending, to the IAB node, a backhaul adaptation protocol (BAP) address that is of the DU of the IAB donor and that corresponds to the one or more IP addresses.
