Abstract

Claims (34)

1. An apparatus for performing a network function, the apparatus comprising:

at least one memory; and

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

receive, at a first integrated access and backhaul node, a resource configuration corresponding to a second integrated access and backhaul node, wherein the resource configuration comprises information indicating soft resources;

obtain an activation parameter corresponding to the second integrated access and backhaul node, wherein the activation parameter comprises a first value, a second value, or a combination thereof, and wherein obtaining the activation parameter comprises receiving an indication of a radio link failure associated with a link between the second integrated access and backhaul node and a master node of the second integrated access and backhaul node; and

determine whether the activation parameter comprises the first value; and

transmit an availability indication message corresponding to a subset of the soft resources in response to determining that the activation parameter comprises the first value,

wherein the first integrated access and backhaul node is a secondary node of the second integrated access and backhaul node.

2. The apparatus of claim 1 , wherein the at least one processor is configured to cause the apparatus to receive the activation parameter from an integrated access and backhaul donor.

3. The apparatus of claim 1 , wherein the first integrated access and backhaul node is a secondary node of the second integrated access and backhaul node, and the at least one processor is configured to cause the apparatus to receive an availability indication request associated with a link between the second integrated access and backhaul node and a master node of the second integrated access and backhaul node.

4. The apparatus of claim 1 , wherein the at least one processor is configured to cause the apparatus to receive a request message from the second integrated access and backhaul node.

5. An apparatus for performing a network function, the apparatus comprising:

at least one memory; and

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

receive, at a first integrated access and backhaul node, a resource configuration, wherein the resource configuration comprises information indicating soft resources;

receive an availability indication message corresponding to a subset of the soft resources;

determine whether the availability indication message is valid based on a radio link failure; and

use the subset of the soft resources in response to determining that the availability indication message is valid.

6. The apparatus of claim 5 , wherein the at least one processor is configured to cause the apparatus to determine whether the availability indication message is valid based on a configuration.

7. The apparatus of claim 5 , wherein the availability indication message is received from a secondary node of the first integrated access and backhaul node, and the radio link failure is associated with a link between the first integrated access and backhaul node and a master node of the first integrated access and backhaul node.

8. The apparatus of claim 5 , wherein the at least one processor is configured to cause the apparatus to determine whether a difference between a first time corresponding to receiving the availability indication message and a second time corresponding to the subset of the soft resources is not larger than a threshold.

9. The apparatus of claim 8 , wherein the threshold is determined based on an expiration of a timer, obtained by a configuration, determined based on a subcarrier spacing, or some combination thereof, and the timer is configured by an integrated access and backhaul donor.

10. An apparatus for performing a network function, the apparatus comprising:

at least one memory; and

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

receive, at an integrated access and backhaul donor, first information indicating a first link between a first integrated access and backhaul node and a second integrated access and backhaul node;

receive second information indicating a second link between the first integrated access and backhaul node and a third integrated access and backhaul node;

transmit a resource configuration to the first integrated access and backhaul node, wherein the resource configuration comprises third information indicating soft resources;

transmit a first activation parameter to the second integrated access and backhaul node corresponding to the first link;

receive fourth information indicating a radio link failure corresponding to the first link; and

transmit a second activation parameter to the third integrated access and backhaul node corresponding to the second link.

11. The apparatus of claim 10 , wherein the at least one processor is configured to cause the apparatus to transmit a third activation parameter to the third integrated access and backhaul node corresponding to the first link.

12. The apparatus of claim 10 , wherein the at least one processor is configured to cause the apparatus to transmit fifth information of a threshold, wherein the threshold is associated with a validity of an availability indication message.

13. The apparatus of claim 12 , wherein the availability indication message is associated with the soft resources.
