1. A first base station central unit (CU) for wireless communication, comprising:
a memory; and
one or more processors, coupled to the memory, configured to:
receive, from a second base station CU, inter-CU signaling that includes information related to cross-link interference (CLI) experienced by or to be measured by one or more victim downstream nodes associated with the second base station CU, the inter-CU signaling indicating time and/or frequency resources that the one or more victim downstream nodes are configured to use to measure CLI; and
configure one or more aggressor downstream nodes associated with the first base station CU to transmit one or more signals for CLI measurements by the one or more victim downstream nodes based at least in part on the time and/or frequency resources indicated by the inter-CU signaling received from the second base station CU.
