Abstract
A method, system and apparatus are disclosed for preventing reestablishment at descendant nodes with no alternative paths in Integrated Access Backhaul (IAB) networks. In one embodiment, a method implemented in a network node configured to communicate with at least one descendant node over a backhaul network includes transmitting an indication to the at least one descendant network node in which the indication is associated with a radio link failure; and receiving at least one message in response to the indication, the at least one message being associated with an alternative path availability of the at least one descendant network node toward a third network node.

A method implemented in a network node configured to communicate with at least one descendant network node over a backhaul network, the method comprising:
- transmitting an indication to the at least one descendant network node, the indication associated with a radio link failure;
- and
- receiving at least one message in response to the indication, the at least one message associated with an alternative path availability of the at least one descendant network node toward a third network node.

A method implemented in a first network node that is configured to communicate with a second network node over a backhaul network, the method comprising:
- receiving, from the second network node, an indication associated with a radio link failure;
- and
- transmitting at least one message to the second network node in response to the indication, the at least one message associated with an alternative path availability of the first network node toward a third network node.

A network node configured to communicate with at least one descendant network node over a backhaul network, the network node comprising processing circuitry, the processing circuitry configured to cause the network node to:
- transmit an indication to the at least one descendant network node, the indication associated with a radio link failure;
- and
- receive at least one message in response to the indication, the at least one message associated with an alternative path availability of the at least one descendant network node toward a third network node.

A first network node that is configured to communicate with a second network node over a backhaul network, the first network node comprising processing circuitry, the processing circuitry configured to cause the first network node to:
- receive, from the second network node, an indication associated with a radio link failure;
- and
- transmit at least one message to the second network node in response to the indication, the at least one message associated with an alternative path availability of the first network node toward a third network node.

-48. (canceled)
A method implemented in a first network node configured to communicate with at least one descendant network node over a backhaul network, the method comprising:
- transmitting a first message type to the at least one descendant network node, the first message type indicating a backhaul link radio link failure and the first message type triggering at the at least one descendant network node at least one of:
- a reduction of scheduling resource requests;
- stopping scheduling resource requests;
- and
- using an alternative route to a donor Integrated Access Backhaul, IAB, network node.
(canceled)
A method implemented in a first network node configured to communicate with a second network node over a backhaul network, the method comprising:
- receiving a first message type from the second network node, the first message type indicating a backhaul link radio link failure and the first message type triggering at least one of:
- a reduction of scheduling resource requests to the second network node;
- stopping scheduling resource requests to the second network node;
- and
- using an alternative route to a donor Integrated Access Backhaul, IAB, network node.
