Abstract

Aspects generally relate to wireless communication. In some aspects, an integrated access and backhaul (IAB) node may receive a configuration that indicates multiple resource patterns for one or more slots, wherein each resource pattern corresponds to a different set of one or more resource block (RB) sets within the one or more slots, and wherein each resource pattern includes at least one of: a resource availability pattern that indicates at least one of hard resources, soft resources, or not available resources for one or more RB sets corresponding to that resource pattern, or a resource directionality pattern that indicates at least one of uplink resources, downlink resources, or flexible resources for the one or more RB sets corresponding to that resource pattern. The IAB node may apply a resource pattern, of the multiple resource patterns, based at least in part on the configuration. Numerous other aspects are described.

First claim

What is claimed is:

1. An integrated access and backhaul (IAB) node for wireless communication, comprising:
a one or more memories; and
one or more processors, coupled to the one or more memories, configured to:
receive a configuration that indicates multiple resource patterns for one or more slots, wherein each resource pattern corresponds to a different set of one or more resource block (RB) sets within the one or more slots and within a same component carrier, wherein the configuration indicates a maximum number of RB sets, within a component carrier, to which the multiple resource patterns can be applied, and wherein each resource pattern includes at least one of:
a resource availability pattern that indicates at least one of hard resources, soft resources, or not available resources for one or more RB sets corresponding to that resource pattern, or
a resource directionality pattern that indicates at least one of uplink resources, downlink resources, or flexible resources for the one or more RB sets corresponding to that resource pattern; and

apply one or more resource patterns, of the multiple resource patterns, based at least in part on the configuration.

2. The IAB node of claim 1 , wherein a first resource pattern, of the multiple resource patterns, includes a first resource availability pattern that indicates at least one of hard resources, soft resources, or not available resources for one or more first RB sets corresponding to the first resource pattern; and
wherein a second resource pattern, of the multiple resource patterns, includes a second resource availability pattern that indicates at least one of hard resources, soft resources, or not available resources for one or more second RB sets corresponding to the second resource pattern.

3. The IAB node of claim 1 , wherein a first resource pattern, of the multiple resource patterns, includes a first resource directionality pattern that indicates at least one of uplink resources, downlink resources, or flexible resources for one or more first RB sets corresponding to the first resource pattern; and
wherein a second resource pattern, of the multiple resource patterns, includes a second resource directionality pattern that indicates at least one of uplink resources, downlink resources, or flexible resources for one or more second RB sets corresponding to the second resource pattern.

4. The IAB node of claim 1 , wherein the multiple resource patterns are multiple slot configuration items indicated in a slot configuration list.

5. The IAB node of claim 1 , wherein each of the multiple resource patterns is indicated in a separate cell resource configuration of a configuration message.

6. The IAB node of claim 1 , wherein the multiple resource patterns include different resource patterns per child node or per backhaul link.

7. The IAB node of claim 1 , wherein each RB set, of the one or more RB sets within the one or more slots and within the same component carrier, includes a group of contiguous RBs.

8. The IAB node of claim 1 , wherein each RB set, of the one or more RB sets within the one or more slots and within the same component carrier, is a same size except for at most one RB set of the one or more RB sets.

9. The IAB node of claim 1 , wherein a respective size of each RB set, of the one or more RB sets within the one or more slots and within the same component carrier, is configured by a control node.

10. The IAB node of claim 1 , wherein an association between a resource pattern, of the multiple resource patterns, and a corresponding RB set is indicated based at least in part on an order in which the resource pattern occurs in a list included in the configuration.

11. The IAB node of claim 1 , wherein an association between a resource pattern, of the multiple resource patterns, and a corresponding one or more RB sets is indicated in the configuration.

12. The IAB node of claim 1 , wherein the configuration further indicates a number of slots to which a resource pattern, of the multiple resource patterns, applies.

13. The IAB node of claim 1 , wherein the one or more resource patterns include a default resource pattern that is applied to an RB set based at least in part on a determination that the configuration does not explicitly indicate an association between the RB set and a resource pattern.

14. A control node for wireless communication, comprising:
a one or more memories; and
one or more processors, coupled to the one or more memories, configured to:
transmit a configuration that indicates multiple resource patterns for one or more slots, wherein each resource pattern corresponds to a different set of one or more resource block (RB) sets within the one or more slots and within a same component carrier, wherein the configuration indicates a maximum number of RB sets, within a component carrier, to which the multiple resource patterns can be applied, and wherein each resource pattern includes at least one of:
a resource availability pattern that indicates at least one of hard resources, soft resources, or not available resources for one or more RB sets corresponding to that resource pattern, or
a resource directionality pattern that indicates at least one of uplink resources, downlink resources, or flexible resources for the one or more RB sets corresponding to that resource pattern; and

apply one or more resource patterns, of the multiple resource patterns, based at least in part on the configuration.

15. The control node of claim 14 , wherein a first resource pattern, of the multiple resource patterns, includes a first resource availability pattern that indicates at least one of hard resources, soft resources, or not available resources for one or more first RB sets corresponding to the first resource pattern; and
wherein a second resource pattern, of the multiple resource patterns, includes a second resource availability pattern that indicates at least one of hard resources, soft resources, or not available resources for one or more second RB sets corresponding to the second resource pattern.

16. The control node of claim 14 , wherein a first resource pattern, of the multiple resource patterns, includes a first resource directionality pattern that indicates at least one of uplink resources, downlink resources, or flexible resources for one or more first RB sets corresponding to the first resource pattern; and
wherein a second resource pattern, of the multiple resource patterns, includes a second resource directionality pattern that indicates at least one of uplink resources, downlink resources, or flexible resources for one or more second RB sets corresponding to the second resource pattern.

17. The control node of claim 14 , wherein the multiple resource patterns are multiple slot configuration items indicated in a slot configuration list.

18. The control node of claim 14 , wherein each of the multiple resource patterns is indicated in a separate cell resource configuration of a configuration message.

19. The control node of claim 14 , wherein the multiple resource patterns include different resource patterns per child node or per backhaul link.

20. The control node of claim 14 , wherein each RB set, of the one or more RB sets within the one or more slots and within the same component carrier, includes a group of contiguous RBs.

21. The control node of claim 14 , wherein each RB set, of the one or more RB sets within the one or more slots and within the same component carrier, is a same size except for at most
