Abstract

The present disclosure provides a source integrated access and backhaul (IAB)-central unit (CU) in a communication system and a method thereof. The method may comprise: sending, to a target IAB-CU, a request message including information for requesting to configure a relay node to migrate; and receiving, from the target IAB-CU, a response message including information for configuring the relay node to migrate.

Claims (36)

1 . A method performed by a first integrated access and backhaul (IAB) donor in a wireless communication system, the method comprising:

transmitting, to a second IAB donor, a request message including first information related to a first address assigned to an integrated access and backhaul IAB) node and address request information indicating a request of address assignment; and

receiving, from the second IAB donor, a response message in response to the request message,

wherein second information related to a second address configured to the IAB node is included in the response message based on the address request information.

2 . The method of claim 1 , wherein the first address assigned to the IAB node includes at least one of an internet protocol (IP) version 4 (IPv4) address assigned to the IAB node or an IP version 6 (IPv6) address assigned to the IAB node.

3 . The method of claim 1 , wherein the address request information includes at least one of a request of internet protocol (IP) version 4 (IPv4) address assignment or a request of IP version 6 (IPv6) address assignment.

4 . The method of claim 1 , wherein the address request information includes at least one of information related to a number of requested addresses for all traffic, information related to a number of requested addresses for F1-C traffic, information related to a number of requested addresses for F1-U traffic, or information related to a number of requested addresses for non-F1 traffic.

5 . The method of claim 1 , wherein the second information includes at least one of an internet protocol (IP) version 4 (IPv4) address assigned to the IAB node, an IP version 6 (IPv6) address assigned to the IAB node, information indicating usage of the IPv4 address or the IPv6 address, or an address of an IAB-donor-distributed unit (DU).

6 . A method performed by a second integrated access and backhaul (IAB) donor in a wireless communication system, the method comprising:

receiving, from a first IAB donor, a request message including first information related to a first address assigned to an integrated access and backhaul (IAB) node and address request information indicating a request of address assignment; and

transmitting, to the first IAB donor, a response message in response to the request message,

wherein second information related to a second address configured to the IAB node is included in the response message based on the address request information.

7 . The method of claim 6 , wherein the first address assigned to the IAB node includes at least one of an internet protocol (IP) version 4 (IPv4) address assigned to the IAB node or an IP version 6 (IPv6) address assigned to the IAB node.

8 . The method of claim 6 , wherein the address request information includes at least one of a request of internet protocol (IP) version 4 (IPv4) address assignment or a request of IP version 6 (IPv6) address assignment.

9 . The method of claim 6 , wherein the address request information includes at least one of information related to a number of requested addresses for all traffic, information related to a number of requested addresses for F1-C traffic, information related to a number of requested addresses for F1-U traffic, or information related to a number of requested addresses for non-F1 traffic.

10 . The method of claim 6 , wherein the second information includes at least one of an internet protocol (IP) version 4 (IPv4) address assigned to the IAB node, an IP version 6 (IPv6) address assigned to the IAB node, information indicating usage of the IPv4 address or the IPv6 address, or an address of an IAB-donor-distributed unit (DU).

11 . A first integrated access and backhaul (IAB) donor in a wireless communication system, the first IAB donor comprising:

a transceiver; and

at least one processor coupled to the transceiver, and configured to:

transmit, to a second IAB donor, a request message including first information related to a first address assigned to an integrated access and backhaul (IAB) node and address request information indicating a request of address assignment, and

receive, from the second IAB donor, a response message in response to the request message,

wherein second information related to a second address configured to the IAB node is included in the response message based on the address request information.

12 . The first IAB donor of claim 11 , wherein the first address assigned to the IAB node includes at least one of an internet protocol (IP) version 4 (IPv4) address assigned to the IAB node or an IP version 6 (IPv6) address assigned to the IAB node.

13 . The first IAB donor of claim 11 , wherein the address request information includes at least one of a request of internet protocol (IP) version 4 (IPv4) address assignment or a request of IP version 6 (IPv6) address assignment.

14 . The first IAB donor of claim 11 , wherein the address request information includes at least one of information related to a number of requested addresses for all traffic, information related to a number of requested addresses for F1-C traffic, information related to a number of requested addresses for F1-U traffic, or information related to a number of requested addresses for non-F1 traffic.

15 . The first IAB donor of claim 11 , wherein the second information includes at least one of an internet protocol (IP) version 4 (IPv4) address assigned to the IAB node, an IP version 6 (IPv6) address assigned to the IAB node, information indicating usage of the IPv4 address or the IPv6 address, or an address of an IAB-donor-distributed unit (DU).

16 . A second integrated access and backhaul (IAB) donor in a wireless communication system, the second IAB donor comprising:

a transceiver; and

at least one processor coupled to the transceiver, and configured to:

receive, from a first IAB donor, a request message including first information related to a first address assigned to an integrated access and backhaul IAB) node and address request information indicating a request of address assignment, and

transmit, to the first IAB donor, a response message in response to the request message,

wherein second information related to a second address configured to the IAB node is included in the response message based on the address request information.

17 . The second IAB donor of claim 16 , wherein the first address assigned to the IAB node includes at least one of an internet protocol (IP) version 4 (IPv4) address assigned to the IAB node or an IP version 6 (IPv6) address assigned to the IAB node.

18 . The second IAB donor of claim 16 , wherein the address request information includes at least one of a request of internet protocol (IP) version 4 (IPv4) address assignment or a request of IP version 6 (IPv6) address assignment.

19 . The second IAB donor of claim 16 , wherein the address request information includes at least one of information related to a number of requested addresses for all traffic, information related to a number of requested addresses for F1-C traffic, information related to a number of requested addresses for F1-U traffic, or information related to a number of requested addresses for non-F1 traffic.

20 . The second IAB donor of claim 16 , wherein the second information includes at least one of an internet protocol (IP) version 4 (IPv4) address assigned to the IAB node, an IP version 6 (IPv6) address assigned to the IAB node, information indicating usage of the IPv4 address or the IPv6 address, or an address of an IAB-donor-distributed unit (DU).
