Abstract

Apparatuses, methods, and systems are disclosed for transmitting and/or receiving device information in a context setup request. One method ( 800 ) includes transmitting ( 802 ) a context setup request to a first device. The context setup request includes information corresponding to a second device. The method ( 800 ) includes receiving ( 804 ) a response to the context setup request.

Claims (40)

1. A method performed by a first device in an integrated access backhaul (IAB) system, the method comprising:

transmitting a user equipment (UE) context modification request message comprising an indication to a third device to stop data transmissions corresponding to a second device, wherein the first device comprises a first IAB node, the second device comprises a second IAB node of the IAB system, and the third device comprises a third IAB node of the IAB system; and

receiving a UE context modification response message in response to the UE context modification request message, the UE context modification response message comprising at least one of:

a confirmation of an update to routing information, the update made in response to the UE context modification request message; and

a downlink data delivery status.

2. The method of claim 1 , wherein the data transmissions comprise uplink data, downlink data, or a combination thereof.

3. The method of claim 1 , wherein the indication comprises an identifier corresponding to the second device, and the data transmissions served by the second device are stopped based on the indication.

4. The method of claim 1 , wherein the indication comprises a set of user device identifiers, and the data transmissions corresponding to the set of user device identifiers are stopped based on the indication.

5. The method of claim 1 , wherein the indication comprises a set of user device specific bearer identifiers, and the data transmissions corresponding to the set of user device specific bearer identifiers are stopped based on the indication.

6. The method of claim 1 , wherein the indication is configured by radio resource control signaling.

7. The method of claim 1 , wherein the indication is included in an adaptative layer.

8. The method of claim 1 , wherein the third device comprises an intermediate node, a parent node, or a combination thereof.

9. The method of claim 1 , wherein the UE content modification request message is transmitted from a central unit.

10. The method of claim 1 , wherein the UE content modification request message is transmitted from an access backhaul node, a child backhaul node, or a combination thereof.

11. A first device in an integrated access backhaul (IAB) system, the first device comprising:

at least one memory; and

at least one processor coupled with the at least one memory and configured to cause the first device to:

transmit a user equipment (UE) context modification request message comprising an indication to a third device to stop data transmissions corresponding to a second device, wherein the first device comprises a first IAB node, the second device comprises a second IAB node of the IAB system, and the third device comprises a third IAB node of the IAB system; and

receive a UE context modification response message in response to the UE context modification request message, the UE context modification response message comprising at least one of:

a confirmation of an update to routing information, the update made in response to the UE context modification request message; and

a downlink data delivery status.

12. A method performed by a third device in an integrated access backhaul (IAB) system, the method comprising:

receiving, from a first device in the IAB system, a user equipment (UE) context modification request message comprising an indication at the third device to stop data transmissions corresponding to a second device, wherein the first device comprises a first IAB node, the second device comprises a second IAB node of the IAB system, and the third device comprises a third IAB node; and

transmitting a UE context modification response message in response to the UE context modification request message, the UE context modification response message comprising at least one of:

a confirmation of an update to routing information, the update made in response to the UE context modification request message; and

a downlink data delivery status.

13. The method of claim 12 , wherein the data transmissions comprise uplink data, downlink data, or a combination thereof.

14. The method of claim 12 , wherein the indication comprises an identifier corresponding to the second device, and the data transmissions served by the second device are stopped based on the indication.

15. The method of claim 12 , wherein the indication comprises a set of user device identifiers, and the data transmissions corresponding to the set of user device identifiers are stopped based on the indication.

16. The method of claim 12 , wherein the indication comprises a set of user device specific bearer identifiers, and the data transmissions corresponding to the set of user device specific bearer identifiers are stopped based on the indication.

17. The method of claim 12 , wherein the indication is configured by radio resource control signaling.

18. The method of claim 12 , wherein the indication is included in an adaptative layer.

19. The method of claim 12 , wherein the third device comprises an intermediate node, a parent node, or a combination thereof.

20. A third device in an integrated access backhaul (IAB) system, the third device comprising:

at least one memory; and

at least one processor coupled with the at least one memory and configured to cause the third device to:

receive, from a first device in the IAB system, a user equipment (UE) context modification request message comprising an indication at the third device to stop data transmissions corresponding to a second device, wherein the first device comprises a first IAB node, the second device comprises a second IAB node of the IAB system, and the third device comprises a third IAB node; and

transmit a UE context modification response message in response to the UE context modification request message, the UE context modification response message comprising at least one of:

a confirmation of an update to routing information, the update made in response to the UE context modification request message; and

a downlink data delivery status.
