Claims

1. Method of operating an Integrated Access and Backhaul, IAB node (200, C, N3) in a radio access network, the method comprising performing, by the IAB node (200,

1445 N1 , N2), power control for a first communication link between the IAB node (200, N1 ,

N2) and a power-controlled radio node (10, 200, N3) based on power control information, the power control information pertaining to a second communication link between the power-controlled radio node (10, 200, N3) and a second IAB node (200, N2, N1 ).

1450

2. Network node (200) for a radio access network, the network node being an Integrated Access and Backhaul, IAB, node (200, N1 , N2), the IAB node (200, N1 , N2) being adapted for performing power control for a first communication link between the IAB node (200, N1 , N2) and a power-controlled radio node (10, 200, N3)

1455 based on power control information, the power control information pertaining to a second communication link between the power-controlled radio node (10, 200, N3) and a second IAB node (200, N2, N1 ).

3. Method of operating a parent IAB node, the parent IAB node being connected to a

1460 first child IAB node (200, N1 , N2) via a first backhaul link and to a second child IAB node (200, N1 , N2) via a second backhaul link, the method comprising providing, to the first child IAB node (200, N1 , N2) power control information, the power control information pertaining to a second communication link between a power-controlled radio node (10, 200, N3) and the second IAB node (200, N2, N1 ).

1465

4. Parent IAB node for a radio access network, the parent IAB node being adapted to be connected or connectable to a first child IAB node (200, N1 , N2) via a first backhaul link and to a second child IAB node (200, N1 , N2) via a second backhaul link, the parent IAB node being adapted for providing, to the first child IAB node (200,

1470 N1 , N2) power control information, the power control information pertaining to a second communication link between a power-controlled radio node (10, 200, N3) and the second IAB node (200, N2, N1 ).

5. Method or device according to one of the preceding claims, wherein the power control information represents a maximum uplink power and/or a difference between uplink powers and/or a target uplink power and/or a target power range.

1480 6. Method or device according to one of the preceding claims, wherein the IAB node

(200, N1 , N2) is a parent IAB node of the power-controlled radio node (100, 200, N3).

7. Method or device according to one of the preceding claims, wherein the power- controlled radio node (100, 200, N3) is an IAB node or a user equipment.

1485

8. Method or device according to one of the preceding claims, wherein performing power control comprises transmitting power control commands, in particular transmit power control, TPC, commands.

1490 9. Method or device according to one of the preceding claims, wherein the power control information is received from the second IAB node (200).

10. Method or device according to one of the preceding claims, wherein the power control information is received from a parent IAB node (200) of the IAB node (200,

1495 N 1 , N2).

11. Method or device according to one of the preceding claims, wherein performing power control comprises transmitting power control information pertaining to the first communication link to the second IAB node (200, N2, N1 )

1500

12. Program product comprising instructions adapted for causing processing circuitry to control and/or perform a method according to one of claims 1 , 3 or 5 to 11.

13. Carrier medium arrangement carrying and/or storing a program product

1505 according to claim 12.
