Abstract

An access node may monitor for uplink and downlink resource release indications signaled by a parent access node and a child access node prior to scheduling a released resource. In some cases (e.g., when the child node is capable of half-duplex communications), the parent access node may determine to release a resource, and the child access node may determine to release a hard resource (e.g., a child node controlled resource). Receiving uplink and downlink resource release indications may enable the access node to schedule communication with the child node via a soft resource (e.g., a parent node controlled resource). Other aspects of the described techniques are directed to feedback support for a slot format indicator (SFI). The feedback from the access node may accept or reject the SFI based on an impact the SFI has on scheduling via a child link established with a child node of the access node.

First claim

What is claimed is:

1 . A method for wireless communication by an access node, comprising:
monitoring for a downlink indication indicating a resource release of a parent node controlled resource, wherein the resource release indicates availability of the parent node controlled resource for a link configured between the access node and a child access node; monitoring for an uplink indication indicating a resource release of a child access node controlled resource that is at least partially overlapping in time with the parent node controlled resource, wherein the resource release of the child access node controlled resource indicates availability of the child access node controlled resource for the link configured between the access node and the child access node; and scheduling the parent node controlled resource for the link configured between the access node and the child access node based at least in part on reception of both the downlink indication and the uplink indication.

2 . The method of claim 1 , further comprising:
monitoring for a second downlink indication and a second uplink indication; determining that one or both of the second downlink indication and the second uplink indication have not been received, and not scheduling the parent node controlled resource based on the determination that the one or both of the second downlink indication and the second uplink indication have not been received.

3 . The method of claim 1 , further comprising:
scheduling a transmission with the child access node via the parent node controlled resource; and transmitting or receiving the transmission via the parent node controlled resource of the link based at least in part on the scheduling.

4 . The method of claim 1 , wherein monitoring for the downlink indication further comprises:
monitoring for a physical downlink control channel message or a downlink medium access control message comprising the downlink indication.

5 . The method of claim 1 , wherein monitoring for the uplink indication further comprises:
monitoring for a physical uplink control channel message or an uplink medium access control message comprising the uplink indication.

6 . The method of claim 1 , wherein monitoring for the downlink indication further comprises:
determining whether the downlink indication is detected based at least in part on an on-off signaling scheme.

7 . The method of claim 1 , wherein monitoring for the uplink indication further comprises:
determining whether the uplink indication is detected based at least in part on an on-off signaling scheme.

8 . The method of claim 1 , wherein monitoring for the downlink indication further comprises:
identifying a multiplexing mode, wherein the multiplexing mode comprises a time division multiplexing (TDM) mode, a spatial division multiplexing (SDM) mode, or a frequency division multiplexing (FDM) mode; and monitoring for the downlink indication and the uplink indication based at least in part on the multiplexing mode.

9 . The method of claim 1 , wherein the downlink indication comprises a message including a bit, field, or flag indicating the parent node controlled resource.

10 . The method of claim 1 , wherein the uplink indication comprises a message including a bit, field, or flag indicating the child access node controlled resource.

11 . An apparatus for wireless communication by an access node, comprising:
a processor, memory in electronic communication with the processor; and instructions stored in the memory and executable by the processor to cause the apparatus to:
monitor for a downlink indication indicating a resource release of a parent node controlled resource, wherein the resource release indicates availability of the parent node controlled resource for a link configured between the access node and a child access node;
monitor for an uplink indication indicating a resource release of a child access node controlled resource that is at least partially overlapping in time with the parent node controlled resource, wherein the resource release of the child access node controlled resource indicates availability of the child access node controlled resource for the link configured between the access node and the child access node; and
schedule the parent node controlled resource for the link configured between the access node and the child access node based at least in part on reception of both the downlink indication and the uplink indication.

12 . The apparatus of claim 11 , wherein the instructions are executable by the processor to cause the apparatus to:
monitor for a second downlink indication and a second uplink indication; determine that one or both of the second downlink indication and the second uplink indication have not been received, and determine to not schedule the parent node controlled resource based on the determination that the one or both of the second downlink indication and the second uplink indication have not been received.

13 . The apparatus of claim 11 , wherein the instructions are further executable by the processor to cause the apparatus to:
schedule a transmission with the child access node via the parent node controlled resource; and transmit or receive the transmission via the parent node controlled resource of the link based at least in part on the scheduling.

14 . The apparatus of claim 11 , wherein the instructions to monitor for the downlink indication further are executable by the processor to cause the apparatus to:
monitor for a physical downlink control channel message or a downlink medium access control message comprising the downlink indication.

15 . The apparatus of claim 11 , wherein the instructions to monitor for the uplink indication further are executable by the processor to cause the apparatus to:
monitor for a physical uplink control channel message or an uplink medium access control message comprising the uplink indication.

16 . The apparatus of claim 11 , wherein the instructions to monitor for the downlink indication further are executable by the processor to cause the apparatus to:
determine whether the downlink indication is detected based at least in part on an on-off signaling scheme.

17 . The apparatus of claim 11 , wherein the instructions to monitor for the uplink indication further are executable by the processor to cause the apparatus to:
determine whether the uplink indication is detected based at least in part on an on-off signaling scheme.

18 . The apparatus of claim 11 , wherein the instructions to monitor for the downlink indication further are executable by the processor to cause the apparatus to:
identify a multiplexing mode, wherein the multiplexing mode comprises a time division multiplexing (TDM) mode, a spatial division multiplexing (SDM) mode, or a frequency division multiplexing (FDM) mode; and monitor for the downlink indication and the uplink indication based at least in part on the multiplexing mode.

19 . The apparatus of claim 11 , wherein the downlink indication comprises a message including a bit, field, or flag indicating the parent node controlled resource.

20 . The apparatus of claim 11 , wherein the uplink indication comprises a message including a bit, field, or flag indicating the child access node controlled resource.

21 . An apparatus for wireless communication by an access node, comprising:
means for monitoring for a downlink indication indicating a resource release of a parent node controlle
