Time division duplexing downlink-uplink configuration signaling

A first wireless node for wireless communication, comprising:

• a memory;
• and
• one or more processors, coupled to the memory, configured to cause the first wireless node to:
• receive, from a second wireless node and in an F1 setup message or a configuration update message, an intended time division duplexing (TDD) downlink-uplink (DL-UL) configuration of one or more cells of the second wireless node, wherein:
• the intended TDD DL-UL configuration identifies a slot format for a slot,
• the first wireless node is a central unit, and
• the second wireless node is a distributed unit;
• and
• communicate with one or more third wireless nodes in the slot in accordance with the slot format indicated by the second wireless node.
