A set of full duplex sub-band patterns, which each define downlink or uplink full duplex frequency sub-band resources during a TDD radio timing unit, are configured to RANs that are neighbors to one another. A RAN determines a traffic load, selects a full duplex sub-band pattern to accommodate the traffic load, and transmits an index associated with the selected pattern to neighboring RANs over a backhaul link. Selecting the pattern may be based on potential CLI. A neighboring RAN may adopt the selected pattern for downlink transmission. A RAN may select a compression subspace plan from among configured subspace plans and transmit, via a backhaul link, an index associated with the compression plan to neighboring RANs for use thereby in performing downlink transmission to minimize CLI. A RAN may transmit, via a backhaul link, an index associated with configured aggressor RAN action based on an uplink traffic or channel type.
