## Abstract

One or more methods for an integrated access and backhaul (IAB) wireless network. At least one of the methods includes determining, by an IAB node including a mobile termination (MT) block and a co-located distributed unit (DU) block, two slot format indications (SFIs) by configuring the co-located DU block, the two SFIs indications including a first SFI that indicates a resource availability for communicating with a parent node and a second SFI that indicates a soft resource availability for communicating with a child node, in which each of the two SFIs include at least one RRCconfigured slot formats; and transmitting the two SFI indications to a second DU block.

## Claims

### Claim 1

A method for an integrated access and backhaul (IAB) wireless network, comprising:
determining, by an IAB node comprising a mobile termination (MT) block and a co-located distributed unit (DU) block, two slot format indications (SFIs) by configuring the co-located DU block, the two SFIs indications comprising a first SFI that indicates a resource availability for communicating with a parent node and a second SFI that indicates a soft resource availability for communicating with a child node, wherein each of the two SFIs comprise at least one RRC-configured slot formats; and
transmitting the two SFI indications to a second DU block;
the method further comprising configuring a first DU block of the IAB wireless network with a plurality of slot format lists, each list of the plurality of slot format lists corresponding to one child link of the first DU;
wherein each child link is configured with a slot format combination based on a multi-slot scheduling mechanism.

### Claim 2 (depends on 1)

The method of claim 1, wherein configuring the co-located DU block comprises configuring the co-located DU block with a different SFI Radio Network Temporary Identity (RNTI) than the MT block.

### Claim 3 (depends on 1)

The method of claim 1, wherein, configuring the co-located DU block comprises configuring the co-located DU block with RRC-configured slot formats that are the same as RRC-configured slot formats as the MT block.

### Claim 4 (depends on 1)

The method of claim 1, wherein configuring the co-located DU block comprises configuring the co-located DU block with RRC configured slot formats that are different than RRC-configured slot formats of the MT block.

### Claim 5 (depends on 1)

The method of claim 1, wherein configuring the co-located DU block comprises configuring the co-located DU block with a different control resource set (CORESET) than a CORESET of the MT block.

### Claim 6 (depends on 1)

The method of claim 1, wherein configuring the co-located DU block comprises configuring the co-located DU block with a different search space than a search space of the MT block.

### Claim 7

A non-transitory computer-readable media comprising instructions to cause an electronic device, upon execution of the instructions by one or more processors of the electronic device, to perform:
determining, by an IAB node comprising a mobile termination (MT) block and a co-located distributed unit (DU) block of an integrated access and backhaul (IAB) wireless network, two slot format indications (SFIs) by configuring the co-located DU block, the two SFIs indications comprising a first SFI that indicates a resource availability for communicating with a parent node and a second SFI that indicates a soft resource availability for communicating with a child node, wherein each of the two SFIs comprise at least one RRC-configured slot formats; and
transmitting the two SFI indications to a second DU block;
wherein the instructions cause the electronic device, upon execution of the instructions, to perform configuring a first DU block of the IAB wireless network with a plurality of slot format lists, each list of the plurality of slot format lists corresponding to one child link of the first DU;
wherein each child link is configured with a slot format combination based on a multi-slot scheduling mechanism.

### Claim 8

An apparatus comprising:
one or more processors; and
one or more computer-readable media comprising instructions that, when executed by the one or more processors, cause the one or more processors to perform operations comprising:
determining, by an IAB node comprising a mobile termination (MT) block and a co-located distributed unit (DU) block of an integrated access and backhaul (IAB) wireless network, two slot format indications (SFIs) by configuring the co-located DU block, the two SFIs indications comprising a first SFI that indicates a resource availability for communicating with a parent node and a second SFI that indicates a soft resource availability for communicating with a child node, wherein each of the two SFIs comprise at least one RRC-configured slot formats; and
transmitting the two SFI indications to a second DU block;
wherein the operations further comprise configuring a first DU block of the IAB wireless network with a plurality of slot format lists, each list of the plurality of slot format lists corresponding to one child link of the first DU; and
wherein each child link is configured with a slot format combination based on a multi-slot scheduling mechanism.
