1. A method for wireless communication at a parent wireless node, comprising:
determining that low latency communications having a latency below a threshold are to be performed with a child wireless node;
overriding, autonomously by at least one of a first communication link interface of the parent wireless node, or a second communication link interface of the parent wireless node that is different from the first communication link interface, or a combination thereof, a previously configured resource type for the first communication link interface based at least in part on the low latency communications, wherein the previously configured resource type comprises an unavailable resource type for time and frequency resources where the time and frequency resources are restricted for use by the first communication link interface to an available resource type where the time and frequency resources are available for use by the first communication link interface, and wherein the previously configured resource type comprises at least one of a not available resource type, or a soft resource type indicated as not available, or a combination thereof;
transmitting, from the first communication link interface of the parent wireless node, a grant to the child wireless node indicating that the low latency communications are to be performed; and
communicating, from the first communication link interface of the parent wireless node, the low latency communications with the child wireless node using resources identified in the grant, wherein the resources identified in the grant comprises at least a portion of the time and frequency resources of the overridden previously configured resource type.
