Abstract

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a central entity may determine a set of schedulable resources for a plurality of links associated with a plurality of nodes of a multi-link network; and may provide scheduling information to the plurality of nodes to schedule communication on the plurality of links based at least in part on determining the set of schedulable resources. In some aspects, a node of a network may determine an extended slot format indicator for the node based at least in part on a received extended slot format indicator of a parent node of the node and a received null adjust request from a child node of the node; may provide the determined extended slot format indicator to the child node; and may provide the received null adjust request to the parent node. Numerous other aspects are provided.

First claim

What is claimed is:

1. A method of wireless communication performed by a node of a network, comprising:
receiving, from a parent node of the node, an extended slot format indicator (SFI) providing a dynamic indication of whether a set of resources are schedulable or non-schedulable; and
scheduling, based at least in part on the dynamic indication, one or more resources, of the set of resources, for a link between the node and a child node of the node.

2. The method of claim 1 , wherein the extended SFI is based at least in part on a radio-resource control (RRC) configuration.

3. The method of claim 1 , wherein the scheduled one or more resources is on at least one of a per slot basis, a per slot group basis, a per symbol basis, or aper symbol group basis.

4. The method of claim 1 , wherein scheduling the one or more resources comprises:
scheduling the one or more resources, of the set of resources, per a set of slots of a channel associated with the link between the node and the child node.

5. The method of claim 1 , further comprising:
providing the scheduled one or more resources to the child node.

6. The method of claim 5 , further comprising:
defining one or more slots, as null slots, and one or more symbols as null symbols,
wherein the extended slot format indicator comprises the one or more slots and the one or more symbols, and
wherein providing the scheduled one or more resources or the child node is based at least in part on defining the one or more slots and the one or more symbols.

7. The method of claim 6 , wherein the null slots are not resources allocated for at least one of a synchronization signal block, a physical random access channel, or a type-0 physical downlink control channel.

8. The method of claim 1 , further comprising:
providing the scheduled one or more resources to another node that is another child node of the parent node.

9. The method of claim 8 , wherein receiving the extended SFI comprises:
receiving the extended SFI via a first interface; and
wherein providing the scheduled one or more resources comprises:
providing the scheduled one or more resources to the node via a second interface different from the first interface.

10. The method of claim 1 , wherein scheduling the one or more resources comprises:
scheduling, based at least in part on a value for a dynamic coordination flag associated with the dynamic indication, the one or more resources, of the set of resources, for the link between the node and the child node of the node.

11. The method of claim 1 , wherein the child node is a user equipment.

12. A node for wireless communication, comprising:
a memory; and
one or more processors, coupled to the memory, configured to:
receive, from a parent node of the node, an extended slot format indicator (SFI) providing a dynamic indication of whether a set of resources are schedulable or non-schedulable; and
schedule, based at least in part on the dynamic indication, one or more resources, of the set of resources, for a link between the node and a child node of the node.

13. The node of claim 12 , wherein the extended SFI is based at least in part on a radio-resource control (RRC) configuration.

14. The node of claim 12 , wherein the scheduled one or more resources is on at least one of a per slot basis, a per slot group basis, a per symbol basis, or a per symbol group basis.

15. The node of claim 12 , wherein the one or more processors, to schedule the one or more resources, are configured to:
schedule the one or more resources, of the set of resources, per a set of slots of a channel associated with the link between the node and the child node.

16. The node of claim 12 , wherein the one or more processors are further configured to:
provide the scheduled one or more resources to the child node.

17. The node of claim 16 , wherein the one or more processors are further configured to:
define one or more slots, as null slots, and one or more symbols as null symbols,
wherein the extended slot format indicator comprises the one or more slots and the one or more symbols, and
wherein providing the scheduled one or more resources or the child node is based at least in part on defining the one or more slots and the one or more symbols.

18. The node of claim 17 , wherein the null slots are not resources allocated for at least one of a synchronization signal block, a physical random access channel, or a type-0 physical downlink control channel.

19. The node of claim 12 , wherein the one or more processors are further configured to:
provide the scheduled one or more resources to another node that is another child node of the parent node.

20. The node of claim 19 , wherein the one or more processors, to receive the extended SFI, are configured to:
receive the extended SFI via a first interface; and wherein the one or more processors, to provide the scheduled one or more resources, are configured to:
provide the scheduled one or more resources to the node via a second interface different from the first interface.

21. The node of claim 12 , wherein the one or more processors, to schedule the one or more resources, are configured to:
schedule, based at least in part on a value for a dynamic coordination flag associated with the dynamic indication, the one or more resources, of the set of resources, for the link between the node and the child node of the node.

22. The node of claim 12 , wherein the child node is a user equipment.

23. A non-transitory computer-readable medium storing a set of instructions for wireless communication, the set of instructions comprising:
one or more instructions that, when executed by one or more processors of a node, cause the node to:
receive, from a parent node of the node, an extended slot format indicator (SFI) providing a dynamic indication of whether a set of resources are schedulable or non-schedulable; and
schedule, based at least in part on the dynamic indication, one or more resources, of the set of resources, for a link between the node and a child node of the node.

24. The non-transitory computer-readable medium of claim 23 , wherein the extended SFI is based at least in part on a radio-resource control (RRC) configuration.

25. An apparatus for wireless communication, comprising:
means for receiving, from a parent node of a node, an extended slot format indicator (SFI) providing a dynamic indication of whether a set of resources are schedulable or non-schedulable; and
means for scheduling, based at least in part on the dynamic indication, one or more resources, of the set of resources, for a link between the node and a child node of the node.

26. The apparatus of claim 25 , wherein extended SFI is based at least in part on a radio-resource control (RRC) configuration.

27. The apparatus of claim 25 , wherein the scheduled one or more resources is on at least one of a per slot basis, a per slot group basis, a per symbol basis, or aper symbol group basis.

28. The apparatus of claim 25 , wherein the means for scheduling the one or more resources comprises:
means for scheduling the one or more resources, of the set of resources, per a set of slots of a channel associated with the link between the node and the child node.

29. The apparatus of claim 25 , further comprising:
means for providing the scheduled one or more resource
