Techniques for updating resource types

Abstract

A parent access node may establish a first link with a child access node. In some cases, the parent access node may determine to release a resource of the first. The parent access node may transmit downlink signaling indicating release of the resource. As such, the child node may schedule a child link resource (e.g., a parent-controlled resource) corresponding to the released resource. The child node may then communicate with a child node of its own in accordance with the scheduling of the child link resource. In some cases, the resource release indication may be associated with a one-time resource release, or may be associated with a semi-persistent release (e.g., until the parent node reclaims the released resources). In some examples, the child node may transmit an uplink message to request resources from the parent node (e.g., and the resource release may be based on the request).

What is claimed is: 
     
         1 . 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:

 schedule a parent-controlled resource corresponding to the resource of a second link configured between the access node and a child access node based at least in part on the downlink signaling and the timing information; and 
 communicate with the child access node via the parent-controlled resource based at least in part on the scheduling. 
   
     
     
         2 . The apparatus of  claim 1 , wherein the instructions to receive the downlink signaling further are executable by the processor to cause the apparatus to:
 receive the downlink signaling indicating the timing information that indicates a single time period for the resource release.   
     
     
         3 . The apparatus of  claim 1 , wherein the instructions to receive the downlink signaling further are executable by the processor to cause the apparatus to:

         4 . The apparatus of  claim 1 , wherein the instructions are further executable by the processor to cause the apparatus to:
 receive second downlink signaling indicating that at least a portion of a resource corresponding to the resource release is being reclaimed; and   update scheduling of the parent-controlled resource based at least in part on the second downlink signaling.   
     
     
         5 . The apparatus of  claim 1 , wherein the instructions are further executable by the processor to cause the apparatus to:
 transmit an uplink message indicating that at least a portion of a resource corresponding to the resource release is not being used.   
     
     
         6 . The apparatus of  claim 5 , wherein the uplink message is a physical uplink control channel message or an uplink medium access control message. 
     
     
         7 . 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:
 indicate a request to use a parent-controlled resource; 
 receive downlink signaling indicating a resource release for a resource of a first link configured between a parent access node and the access node based at least in part on the request; 
 schedule the parent-controlled resource corresponding to the resource of a second link configured between the access node and a child access node based at least in part on the downlink signaling; and 
 communicate with the child access node via the parent-controlled resource based at least in part on the scheduling. 
   
     
     
         8 . The apparatus of  claim 7 , wherein the instructions to indicate the request further are executable by the processor to cause the apparatus to:
 transmit the request as a physical uplink control channel message, an uplink medium access control message, or a radio resource control message.   
     
     
         9 . The apparatus of  claim 7 , wherein the instructions to indicate the request further are executable by the processor to cause the apparatus to:
 transmit at least one of a traffic load indicator or a resource utilization indicator to indicate the request.   
     
     
         10 . The apparatus of  claim 7 , wherein the instructions to schedule the parent-controlled resource further are executable by the processor to cause the apparatus to:
 schedule a plurality of distributed units of the access node based at least in part on the downlink signaling.   
     
     
         11 . The apparatus of  claim 7 , wherein the instructions to schedule the parent-controlled resource further are executable by the processor to cause the apparatus to:
 identify a subset of a plurality of distributed units of the access node to which the downlink signaling corresponds; and   schedule the subset of the plurality of distributed units of the access node based at least in part on the downlink signaling.   
     
     
         12 . An apparatus for wireless communication by a parent 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:
 establish a first link between the parent access node and a child access node; 
 determine to release a resource of the first link that corresponds to a parent-controlled resource of the child access node; and
