## Abstract

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless node may receive an indication of a first periodic resource associated with the wireless node, wherein the first periodic resource is associated with one or more parameters for coordinating periodic resources or a priority flag that indicates that the first periodic resource is available to the wireless node irrespective of a resource type associated with the first periodic resource. The wireless node may communicate, with a child node or another wireless node, a message using a modified first periodic resource, wherein the modified first periodic resource includes a modified resource allocation associated with the first periodic resource or a modified resource type associated with first periodic resource. Numerous other aspects are provided.
