Some demonstrative embodiments include devices, systems and/or methods of Time-Division Duplexing (TDD) Uplink-Downlink (UL-DL) configuration management. For example, a node may communicate a message including a cell identifier identifying a first cell controlled by the node, and a TDD configuration update to update at least one other node, which controls at least one second cell, with a TDD UL-DL configuration allocated by the node for communication within the first cell.
