Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 3:
4. 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:
sending first information to a centralized unit (CU) of an integrated access and backhaul (IAB) donor, wherein the first information is used to request to allocate internet protocol (IP) address to an IAB node, and wherein the communication apparatus is the IAB node or an apparatus included in the IAB node, 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; and
receiving a backhaul adaptation protocol (BAP) address from the CU of the IAB donor, wherein the BAP address is of a distributed unit (DU) of the IAB donor and the BAP address corresponds to one or more IP addresses that are allocated to the IAB node.
