Assignee: HUAWEI TECHNOLOGIES CO., LTD.
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 9:
10. A communication system, comprising:
a centralized unit (CU) of an integrated access and backhaul (IAB) donor, wherein the CU of the IAB donor comprises:
at least one first processor; and
one or more first memories coupled to the at least one first processor and storing first programming instructions for execution by the at least one first processor to perform first operations comprising:
receiving first information from an IAB node, wherein the first information is used to request to allocate internet protocol (IP) address to 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;
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; and

the IAB node, wherein the IAB node comprises:
at least one second processor; and
one or more second memories coupled to the at least one second processor and storing second programming instructions for execution by the at least one second processor to perform second operations comprising:
sending the first information to the CU of the IAB donor; and
receiving the BAP address from the CU of the IAB donor.
