Dynamic resource management
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.
